The Producer Price Index or PPI is a closely watched fundamental economic indicator that helps forex traders assess how inflationary pressures are faring at the wholesale or producer level for goods. The release of PPI data and its revisions can result in significant forex market volatility.

The changes in the PPI will often be used by fundamental traders and professional economists to quantify fluctuations in the amount of inflation building up in a country's economy.

Specifically, changes seen in the PPI relate to variations in the input costs experienced by a typical producer or provider of consumer goods that then passes these cost changes on to their wholesale customers.

Sometimes also known as "Wholesale Prices" or "Finished Goods PPI", the PPI data is widely considered a leading indicator of inflationary pressures within an economy. As a result, it is often used by central banks as a justification for adjusting interest rates or taking other appropriate monetary policy measures.

Furthermore, since rising inflation generally results in a reduction in the purchasing power of money in an economy, central banks usually have controlling inflation within acceptable levels as one of their primary tasks. Central banks often do this by increasing interest rates to fight rising inflation and by reducing interest rates in a low inflation or deflationary environment.

These factors help make the PPI data especially significant for forex traders because the number can result in shifts in the monetary policy for a nation, especially when changes in the PPI show a significant deviation from normal levels.

What the PPI Indicator is and Measures

The Producer Price Index is a weighted average of the price changes observed in physical goods measured at the wholesale or producer level.

Furthermore, Core PPI in the United States excludes the more volatile price changes often seen in food and energy commodities since their price fluctuations can obscure the underlying trend in wholesale inflation.

These volatile components make up around 40% of overall PPI, so both the Federal Reserve Bank and forex traders tend to focus on the more comprehensive PPI number to assess overall wholesale inflationary pressures within the U.S. economy.

How the PPI Data Affects the Forex Market

The PPI and Core PPI are some of the most closely observed of all of the fundamental indicators for an economy since it acts as a leading indicator for consumer inflation. Essentially, when producers start charging more, the greater costs generally get passed on to consumers.

The forex market also tends to looks more closely at PPI data when it is released before the Consumer Price Index or CPI data since these two key inflation indicators are quite closely correlated.

Furthermore, forex traders tend to focus more on the PPI data itself than on the core PPI number since it is a broader based assessment of the underlying trend in wholesale inflation because it includes the important food and energy elements.

Basically, if the PPI or Core PPI number for a country comes out above the market's expectations, then that tends to increase the value of that country's currency relative to other currencies.

On the other hand, if the PPI or Core PPI comes out below the market's expectations, then that will tend to reduce the value of that country's currency relative to others.

In addition to deviations of the most recent PPI number from expectations causing forex market volatility, revisions to previous numbers can also have a significant market impact.
