What is cpi in forex?
As we covered in the previous lesson, central banks must maintain a tricky balancing act. Most have a dual mandate of maintaining high employment while keeping prices stable – and to keep prices stable you need to manage inflation.
Inflation is the term for when prices rise over time in an economy. It gets its name because prices are being inflated higher each year, just like blowing up a balloon.
While rising prices might seem like a bad thing, they are part of a growing economy. Most economists today believe that a low and stable inflation rate can help reduce the severity of economic downturns by providing a cushion against falling prices, which can be difficult to manage if they become entrenched.
For this reason, central banks will try to keep inflation within acceptable parameters. The Bank of England, for example, has a target of 2%. This means that prices overall should increase by 2% each year.
If inflation drops below 2%, it may consider lowering interest rates to boost the economy and get it back on track. If it goes too high, they could raise rates to slow the economy. Otherwise, they run the risk of hyperinflation.
Hyperinflation occurs when inflation gets out of control. Prices get too high, and the value of currency plummets. Classic examples include Germany before WW2, Russia after the fall of the Soviet Union and Zimbabwe in the mid-2000s.
Usually, hyperinflation leads to a total loss of confidence in an economy and its currency, so central banks are constantly on the watch to avoid it. Some analysts argue that the rise in unconventional monetary measures – such as quantitative easing – in the 2010s could lead to hyperinflation by flooding the market with capital.
Deflation arises when prices are declining – so inflation is below 0%.
To the average person on the street, deflation might seem like a good thing. Who wouldn’t want the things they buy every day to get cheaper?
Well, manufacturers and producers, for one. Deflation means that the margin they make from sales would go down, which hurts their bottom line and may lead to layoffs. As unemployment rises, demand falls, and companies are hurt even more. And what does this lead to? Even more job losses.
This is called a deflation spiral.
To avoid this spiral, central banks may consider easing monetary policy when inflation falls.
These describe changes in the inflation rate:
In the 1990s and 2000s, the Bank of Japan struggled to reverse a stubborn disinflation trend. During this period, inflation remained low and the economy stagnated in a period known as the ‘lost decades’.
As 0% interest rates failed to kickstart consumerism or business activity, with the BoJ eventually turning to quantitative easing, in which a central bank buys bonds and asset-backed securities to increase money supply and introduce inflation.
“Zinflation” is the term we are using for when interest rates stay the same over a period of time. Back in the 1990s the idea of zinflation was something that was debated as being the ultimate goal of central banks and even Federal Reserve Chairman Alan Greenspan expressed a desire to achieve it. Since then, the experience of Japan in the Lost Decades has served to make zinflation less desirable, as it would be likely synonymous with lack of growth for an economy as well. Therefore, the model of low inflation near the 2%-3% level has become the preferred model to begin the 21st century.
The Consumer Price Index (CPI) is an economic indicator that tracks the cost of goods and services and serves as an important statistic for identifying inflation or deflation. Known also as headline inflation, it is a major influencer of interest rate changes based on the inflation targets set by central banks.
The CPI figure is calculated by weighting the average price of a basket of products across goods and services such as groceries, transport costs, and healthcare, and measuring their change in price over time.
When the amount of the currency needed to buy the market basket increases, this is inflation, and when the amount of currency needed to buy the market basket decreases, this constitutes deflation.
The core CPI figure is slightly different as while it still measures the change in price of goods and services, it does not include energy and food prices. These are omitted for this measure as such prices have the tendency to be highly volatile and therefore capable of creating a misleading impression of inflationary pressures.
In the US, the CPI is released monthly by the US Bureau of Labor Statistics and has been reported since 1913. However, in countries such as Australia, the data is released on a quarterly basis, and in Germany, an annual report is issued.
Higher inflation in the form of a higher CPI naturally makes an individual unit of currency worth less, as there are more units of that currency needed to buy a given item.
But more importantly, as with the NFP and GDP, when the CPI changes, central bank monetary policy may follow suit.
High CPI may inspire interest rate hikes by a central bank in an attempt to control the inflationary trend. When a country’s interest rates are higher, it is likely that its currency will strengthen as demand for it increases.
Conversely, lower inflation may lead to decreased interest rates and weaker demand for a country’s currency, prompting consumers to spend, putting more money into circulation, and generally stimulating a slower economy.
So given this information, it’s no surprise that when CPI data is released, forex swings can happen in kind. Sometimes it can create volatile conditions with extreme movement, creating potential for large profits, as well as proportionate risks.
The Consumer Price Index can move forex, which means there are numerous strategies for trading it.
To trade the CPI, you’ll need to be aware of the expectations the market holds for inflation and the likely outcomes for the currency if these expectations are met or missed.
Sometimes, an environment for increased inflation will be welcomed (for example, when deflation is rife), while in more inflationary conditions an increased rate of inflation may be considered bad for the economy.

Analyst expectations for inflation are released on a monthly basis, with their judgments based on supply and demand dynamics, currency prices, and key commodity prices, as well as fiscal and structural measures.
After the CPI release and surrounding analysis, you might want to bring in technical elements to your approach, examining if the price is reacting to key support and resistance levels. Technical indicators may help to give some insight into the short-term strength of the move, for more informed trading decisions.
However, as with other news releases, timing is everything. It may, therefore, be unwise to open a position shortly before an announcement, as forex spreads may widen substantially immediately before and after the report.
In the below chart, US inflation statistics are shown as a percentage of change since the same point 12 months ago. So, for the March 2021 figure, consumer prices were 2.6% higher than at the same point the previous year.
For US traders, the US Dollar Index (USDX), which shows the performance of USD against a basket of other currencies, can be a useful way of exploring the effects of CPI data. If the latest release is divorced from analyst expectations, traders may watch for USDX to move accordingly.
On the March 2021 CPI figures (which were released the following month), USD briefly spiked as the mark was slightly above analyst expectations. However, as it became clearer that interest rate hikes were likely off the agenda for 2021, the USDX fell, a slump aided by languishing US treasury yields.
It is an index that measures the change in the price of a representative basket of goods and services such as food, energy, housing, clothing, transportation, medical care, entertainment, and education.
The CPI is the measurement used by economists for tracking price changes in a typical “basket” of goods and services that consumers purchase.
The Bureau of Labor Statistics (BLS) computes the CPI by taking the average weighted cost of a basket of goods in a given month and dividing it by the weighted cost of the same basket the previous month.
Then, it multiplies this percentage by 100 to get the number for the index.
The CPI measures inflation (a sustained rise in prices in an economy) as experienced by consumers in their day-to-day living expenses
The increase in the CPI is what most people think of as the “inflation rate.”
It is used by retailers in predicting future price increases, by employers in calculating salaries, and by the government in determining cost-of-living increases for Social Security.
Signs of inflation mean the central bank has to raise interest rates. The most widely used indicator of inflation is CPI.
If CPI is increasing, then it gives a central bank such as the Fed the necessary supportive data to hike rates. Higher interest rates are bullish for the country’s currency.
The CPI is a measure of the change over time in the prices paid by consumers for a market basket of goods and services.
These goods and services include food, clothing, shelter, and used cars. Items on which the average consumer spends a great deal of money, such as food, are given more weight, or importance, in computing the index than items such as toothpaste and movie tickets, on which the average consumer spends comparatively less.
The CPI does not include investment items, such as stocks, bonds, real estate, and life insurance. These items relate to savings and not to day-to-day consumption expenses.
Each month, data collectors from the Bureau of Labor Statistics (BLS) called economic assistants visit or call thousands of retail stores, service establishments, rental units, and doctors’ offices, all over the United States to obtain price information on thousands of items used to track and measure price change in the CPI.
These economic assistants record the prices of about 80,000 items each month. These 80,000 prices represent a scientifically selected sample of the prices paid by consumers for the goods and services purchased.
During each call or visit, the economic assistant collects price data on a specific good or service that was precisely defined during an earlier visit.
If the selected item is available, the economic assistant records its price. If the selected item is no longer available, or if there have been changes in the quality or quantity (for example, eggs sold in packages of 8 when previously they had been sold by the dozen) of the good or service since the last time prices had been collected, the economic assistant selects a new item or records the quality change in the current item.
The recorded information is sent to the national office of BLS where commodity specialists, who have detailed knowledge about the particular goods or services priced, review the data.
These specialists check the data for accuracy and consistency and make any necessary corrections or adjustments. These can range from an adjustment for a change in the size or quantity of a packaged item to more complex adjustments based on a statistical analysis of the value of an item’s features or quality.

The Consumer Price Index or CPI as it is more commonly known is also sometimes referred to as the ”Retail Price Index” and is often considered the most widely used and most accurate measure of inflation and tends to also be regarded as an indicator of the effectiveness of the current government policies.
Essentially, the CPI is a “basket” of various consumer goods and services that have been purchased by the wage earners of certain urban areas and which have been tracked from month to month.
The CPI is a fixed quantity price index and also a form of cost of living index and is considered one of the most useful tools in financial circles as it can provide clues as to movements in inflation.
When inflation rises, our purchasing power subsequently falls into decline meaning that every dollar earned is capable of buying a lesser percentage of a good or service. While it is typical for The federal reserve to battle rising inflation by increasing short-term interest rates this is often frowned upon by investors because the cost of borrowing increases.
Close attention needs to be paid to the “core rate” as this rate excludes volatile energy and food prices to give a more strict measurement of general prices.
Ideally, within the financial markets, you would generally be looking for the CPI to rise at an annual rate of just 1-2%, as any amount over this would indicate a warning about growing levels of inflation.
CPI can be greatly influenced in any given month by a movement in volatile food and energy prices. Therefore, it is important to look at CPI excluding food and energy, commonly called the “core” CPI
Within the core CPI, some of the more volatile and closely watched components are apparel, tobacco, airfares, and new cars. In addition to tracking the m/m changes in core CPI, the y/y change in core CPI is seen by most economists as the best measure of the underlying inflation rate.
When the CPI report is released, it’s essential to consider the current market conditions and the broader economic context.
It is a key indicator of inflation, and central banks like the Federal Reserve closely monitor it to make monetary policy decisions.
Here are some factors to consider when interpreting the CPI report:
The Consumer Price Index (CPI) is a critical indicator of pricing pressures in an economy and provides a gauge of inflation. Forex traders monitor the CPI, as it can lead to changes in monetary policy by the central bank that will either strengthen or weaken the currency against rivals in the markets.
When we are caught up in the rush of performing our daily tasks and responsibilities, we miss the small details in life. One of these major details is our regular expenses like housing, transportation, and food. Although we often don’t account for our everyday spending, it is the largest item which drains our livelihood. When the prices in our regular shopping list go up, the amount of free cash in our hand goes down. The increase in prices usually happen in subtle ways, and we are usually unaware of it. This is known as inflation. Basic expenses are mostly the same for everyone, and by monitoring the changes in their prices, we can measure how costly life is getting over time.
Consumer Price Index (CPI) is the main economic indicator that is used to track the inflation rate and the cost of living in a country. It comprises a basket of goods and services and calculates the basket price as a weighted average of the constituent items’ retail prices. CPI is released on a monthly basis, but quarterly and yearly reports are also common. Periodic release of CPI reports allows us to analyse the change in the prices of the individual items as well as the whole basket over time. The rate which the basket price changes over time is also known as the inflation rate. CPI was first created during World War I when an abnormal surge in prices led to the creation of an index to calculate the cost of living adjustments. In 1984, a baseline of 100 was set for CPI figures in the actual report.
If the CPI figure is 140, it would mean that the inflation is 40% higher than the 1984 figure. Nowadays, CPI serves as the main indicator of inflation and helps the national central bank to adjust its monetary policy in accordance with their inflation targets. A consistent level of inflation (i.e., 2%) is considered healthy for a steady economic growth. CPI, like any inflation indicators, it is a lagging indicator in the sense that it informs about the change in a past period. When a country publishes a CPI report, the results are expressed as the percentage of change compared to the previous issue.
If the result is positive, the consumer prices have increased, and the inflation rate is rising. In the opposite scenario, the consumers would be paying less, and inflation would be decreasing. The reaction of markets would depend on the economic conditions of the country. For example, under normal economic conditions, an increasing CPI would encourage the central bank to raise interest rates, which would add value to the currency and attract traders to buy more. However, if the current inflation is too high or the economy is in recession, the stagnant income level of citizens wouldn’t match the rising cost of living and eventually reduce consumer spending over time. Thus, it can create the opposite effect and repel investors away.
Consumer Price Index measures the inflation rate of the consumer prices in an economy by creating a basket of basic goods and services. Generally, CPI baskets include 80 sub-indices from 8 categories, ranging from food and clothing to housing and transportation. Methodologies to comprise the basket and formulas to calculate price indices can differ slightly in each country and region.
There are three different CPI formulas to calculate the price index: Laspeyres, Paasche and Fischer. In the formulas below, the legend is as follows:
Laspeyres Price Index: The items are weighted based on the quantity in the base period.
CPI(L) = Sum of [p(c) x q(b)] for each item / Sum of [p(b) x q(b)] for each item Paasche Price Index: The items are weighted based on the quantity in the current period.
CPI(P) = Sum of [p(c) x q(c)] for each item / Sum of [p(b) x q(c)] for each item Fischer Price Index:Calculates the geometric mean of Laspeyres and Paasche.
CPI(F) = √ [CPI(L) x CPI(P)]Each CPI calculation gives us the ratio between the basket prices of the current period and the base period. The ratio is then multiplied by 100 to express the change in percentages.
Because the inflation rate is measured as the percentage change of a price index (inflation definition), the value of the CPI is closely monitored. The inflation rate formula is as follow:
Inflation Rate = [CPI(c) – CPI(b)] / CPI(b)For the financial markets, the inflation rate indicates the path for future interest rate changes, with immediate implications on current prices. For example, if the CPI deviates abruptly from the central bank’s target, the markets would expect the central bank to step up and raise or cut the interest rate level. This expectation would lead the investors to either buy or sell the currency significantly more.
As the main economic indicator of inflation, Consumer Price Index plays an important role in a central bank’s monetary policy decisions. The central bank of each country is responsible of creating a monetary policy to facilitate economic health and growth. Along with GDP and unemployment rate, inflation is an important aspect of economic growth and the inflation target is usually set between 2% and 3%. Using interest rates as a tool, the central bank can manipulate and control the inflation rate. Interest rate decisions always top the list of most influential economic events and have a powerful impact on the value of the national currency. Since central banks decide on raising or cutting the interest rates based on the performance of the inflation rate, CPI reports are followed closely by investors and analysts and strongly influence the market sentiment towards the currency. The release of CPI report is usually bound to create large-scale volatility in the financial markets, especially in the Forex currency pairs.
There are two ways to look at the CPI release. One is to compare the actual release with the forecast and the previous release. Another is to interpret it according to the central bank’s target. In either case, the outcome triggers volatility and leads to numerous short-term opportunities for news trading strategies. Let’s assume that the U.S. is expected to publish a monthly CPI report. The forecast is 1.3% and the previous result was 1.1% – so, the analysts are anticipating CPI to rise. When the report is released, the actual outcome is 1.5% and beats the forecasts positively. The expectations for the U.S. Federal Reserve to raise interest rates would build-up, and the traders would tend to buy USD. As a result, currency pairs like EUR/USD and USD/CAD move in favor of USD, while equities like Apple stocks and US_Tech100 index might lose value.
The CPI report has different names and different weights in countries around the world (inflation rate formula changes for developed and emerging economies). Some of them are Laspeyres indexes, some Fisher indexes– but they all have a strong impact on the financial markets.
The U.S. CPI covers only the urban area – hence, it is often called CPI-U. However, the Fed doesn’t focus on the classic CPI because it is a Laspeyres index and suffers from upward biases. Therefore, in 2000, the Fed switched to the Fischer-based PCE Index (Private Consumption Expenditure) which covers the complete range of consumer spending and not just a basket.
European Central Bank (ECB) collects individually calculated national CPI from each country and combines them into Harmonized Index of Consumer Prices (HICP) using weighted averaging.
Food weights are higher in the CPI formula for China as a greater proportion of income of the average consumer goes to food.
CPI figures affect the central banks’ decisions on interest rates – therefore, currency prices – directly. Monthly CPI reports are eagerly anticipated as the sudden increase in the trading activity translates into price volatility.

The CPI calculates the weighted average of prices of a basket of consumer goods and services, including costs of transportation, food, and energy. Economists use this CPI figure to assess price changes in individuals’ cost of living.
When inflation is too low, a central bank like the Federal Reserve may cut interest rates in order to spur economic activity. When inflation is too high, interest rates may be raised to stabilize prices. By increasing interest rates, a consumer may be more likely inclined to save money, rather than spend it, due to the return they may generate by keeping it in a bank.
In the foreign exchange (forex) markets, the monthly CPI measure is one of the most important indicators monitored by traders. In the case of the U.S. dollar, the release and revisions of the CPI figure by the Bureau of Labor Statistics can produce swings in the dollar’s value against other currencies around the world.
This article explains how CPI data affects the relationship between the dollar and its pairings with other currencies on the forex market.
Markets typically refer to the CPI indicator as “headline inflation.” This CPI data is critical in the currency markets because inflation dramatically impacts the decisions made by central banks regarding monetary policy.
Given that central banks typically have a mandate to control inflation at a suitable level (the Federal Reserve and the Bank of Japan have both targeted an inflation rate of 2.0% annually), policymakers raise or lower interest rates as a mechanism to reach these target levels. They may also introduce other policy prescriptions such as bond-purchasing agreements or the expansion of the money supply.
Should inflation levels deviate from target levels, it is a possible indicator that central banks like the Federal Reserve may alter interest rates. If inflation rises above that 2.0% target, the Fed may raise interest rates in order to cool down spending. That will strengthen the dollar against other currencies as a higher interest rate makes the greenback more desirable.
It is also a forward indicator of an economy’s performance. Should inflation rise sharply as it has in countries such as Brazil and Venezuela in recent years, consumers will be less inclined to save money as their purchasing power erodes.
Meanwhile, when a central bank hikes interest rates to combat inflation, borrowing, whether by individuals to purchase goods and services or by businesses for the purposes of expanding, will typically contract. This can impact the broader gross domestic product of a nation.
The Federal Reserve has a dual mandate that affects its actions on monetary policy. The central bank wants to bring the economy to full employment and it wants to ensure a healthy rate of inflation as the economy expands.
As a result, forex traders see both unemployment and inflation figures as figures that will dictate the central bank’s future decision on whether to cut, raise or maintain current interest rate levels. Given the impact of an interest rate on the strength or weakness of a currency, traders can anticipate the impact of the central bank’s actions and the impact on the dollar’s performance in currency pairs.
Forex traders consider the CPI and Core CPI figures to be two of the most fundamental indicators for the performance of an economy. Between the two, however, the Core CPI figure provides a better look under the hood by excluding costs in the energy and food sectors, which tend to experience greater price volatility over time.
In the United States, the Labor Department releases the CPI and Core CPI figures, which don't include the costs of energy or food in the measure. Should that number beat market expectations, the dollar typically sees a boost against other currencies. However, should these readings fall short of consensus expectations, the currency will fall relative to other pairings.
However, the impact is not limited to the monthly report. Like all government data figures, the CPI figure is subject to revisions by economists. Such changes can fuel significant volatility in a currency's value on the global market.
Consumer Price Index reveals the weighted average change in prices that consumers pay for a basket of goods and services, such as food, energy, housing, clothing, transportation, medical care, entertainment, and education. Changes in the CPI are used to measure price changes tied to the cost of living. An accurate gauge of changes in the cost of living is essential for different people and organizations such as central banks.
A basket of goods is a fixed group of consumer products and services the price of which is assessed regularly: often on a monthly or annual basis. The aim of creating this basket is to track inflation in a certain market or country. If the price of the basket of goods grows by 2% in a year, inflation can be said to equal 2% as well. The basket of goods is a sample that should represent the overall economy, that’s why some goods are replaced by others periodically to comply with consumer habits.
*The basket of goods consists of basic food and beverages such as milk and coffee. It also covers housing costs, furniture, transportation fees, health care costs, toys, and even tickets to museums. Education and communication costs are listed in the basket as well as other random products such as tobacco, haircuts, and funerals.
Consumer prices account for a majority of overall inflation, that’s why you can notice the term Inflation Rate instead of CPI in our economic calendar. Don’t be confused – they both show the same data.
There are two versions of the reports: Inflation Rate and Core Inflation Rate. The difference between them is simple: the core indicator excludes food and energy prices due to their volatility.
Besides, there are other indicators of inflation such as Producer Price Index (PPI), Wholesale Price Index (WPI), Retail Price Index (RPI). Still, CPI tends to be more impactful in terms of Forex trading.
As we said, the Consumer Price Index is the most common gauge of inflation. It shows to the government, businesses, and citizens how prices have changed in the economy over some period. Based on CPI, retailers predict future price increases, employers calculate salaries and the government defines cost-of-living increases.
When inflation rises, the purchasing power declines, which means that a consumer can buy fewer goods and services for every currency unit (let’s say, 1 dollar). Otherwise, when inflation falls, the purchasing power increases, which means that a consumer can buy more goods and services for every currency unit.
The most interesting thing for traders is that the central banks make policy decisions based on the Consumer Price Index data. Thus, not only the actual CPI data but even traders’ expectations for the CPI release increase volatility in the Forex market.
The release of the Consumer Price Index tends to cause massive movements in the Forex market. Pay attention that it refers only to the countries which currencies are liquid.
Based on liquidity, there are three currency categories in the global Forex trade: majors, minor currency pairs, and exotic currencies. Major currencies are the most popular and liquid. The major currencies include the US dollar, the British pound, the euro, the Japanese yen, the Australian dollar, and the Canadian dollar. Thus, pay closer attention to the CPI releases of the US, UK, Canada, EU, Japan, Australia, and New Zealand.
Traders compare the forecast with the actual CPI data, which you can check in the economic calendar.
It’s a good idea to check the time of the next CPI release before, open the charts with the currency of the country issuing CPI to be fully prepared once it’s out, and monitor the price movement.
What about stocks markets? Are they affected by CPI? Stock markets generally aren’t driven as much by CPI numbers, but sometimes they can be! Higher inflation and consequently higher interest rates can force economic activity to slow. Therefore, as a rule, stock markets favor a lower CPI that lets consumers keep spending, and businesses continue investing even more.
For instance, the Bureau of Labor Statistics revealed the US Consumer Price Index (Inflation Rate) on July 13. The CPI came out greater than expected. Look at the screenshot of the economic calendar below.
As a result, USD/JPY rocketed by 300 points in half an hour after the release! In the chart below, you can observe that huge movement.
Let’s discuss the example when Consumer Price Index fell short of analysts’ expectations. On July 28, Canada’s CPI (Inflation Rate) came out lower than anticipated: 0.3% vs the market estimate of 0.4%.
After the release, CAD/JPY has plunged by 140 points. Such a rapid fall only in 30 minutes! Indeed, economic indicators such as CPI tend to cause huge swings in the charts. Therefore, traders should follow economic releases and monitor the price movement during these events.
The CPI can sometimes be affected by an increase in the price of a certain commodity. For example, a hike in oil prices can impact transportation, food, utilities, and retail sales. The huge increase in the price of one commodity can cause a domino effect, which can make investors and traders change their strategies in the Forex market.
This is so similar to the current situation. Oil and gas prices have been sharply rising in September 2021. These commodities are used in essential activities such as fueling transportation and heating homes, which became even more important before the winter season. Rising commodity prices increase the costs of all these activities and thus push inflation up.
Speaking about the US dollar (the most traded currency in the Forex market), the higher US inflation should push the Federal Reserve to taper stimulus from November and hint at the rate hike earlier than initially thought. Investors expect this to happen and thus invest their capital in the USD. As a result, the USD hit a one-year high!
Other central banks experience high inflation as well these days. However, banks don’t rush to fight it. The Covid-19 crisis makes it harder for central banks to hike rates or reduce bond buys as the economic health of their countries is not good enough. Sooner or later, all of them will start increasing rates, which will push the currencies of these countries up. Therefore, the current CPI reports grab so much attention these days!
