Measures changes in the selling prices producers charge for goods and services, and well as tracks how prices feed through the production process. Because producers tend to pass on higher costs to consumers as higher retail prices, the PPI is valuable as an early indicator of inflation. Simply put, inflation reflects a decline in the purchasing power of the Dollar, where each dollar buys fewer goods and services. The report also gives insight into how higher prices from raw materials flow toward the final product.

A rise in PPI signals an increase in inflationary pressures. Given the economic instability associated with rising price levels, the Fed often will raise interest rates to check inflation. A low or falling PPI is indicative of declining prices, and may suggest an economic slowdown.

The headline figure is expressed in percentage change of producer price.

Notes: The PPI records prices at various stages of production: raw goods, intermediate goods and finished goods. Though intermediate and crude goods prices do provide insight for future inflationary pressure, it is the price of finished goods that generates most interest for market participants. The finished goods data is able to gauge price pressure before the goods reach the retail market.

A country's trade balance reflects the difference between exports and imports of goods and services. The trade balance is one of the biggest components of the Balance of Payment, giving valuable insight into pressures on country's currency.

Surpluses and Deficits
A positive Trade Balance (surplus) indicates that exports are greater than imports. When imports exceed exports, the country experiences a trade deficit. Because foreign goods are usually purchased using foreign currency, trade deficits usually reflect currency leaking out of the country. Such currency outflows may lead to a natural depreciation unless countered by comparable capital inflows (inflows in the form of investments, FDI - where foreigners investing in local equity, bond or real estates markets). At a bare minimum, deficits fundamentally weigh down the value of the currency.

Ramifications of Trade Balance on Markets
There are a number of factors that work to diminish the market impact of Trade Balance upon immediate release. The report is not very timely, coming some time after the reporting period. Developments in many of the figure's components are also typically anticipated well beforehand. Lastly, since the report reflects data for a specific reporting month or quarter, any significant changes in the Trade Balance should plausibly have already been felt during that period - and not during the release of data.

However, because of the overall significance of Trade Balance data in forecasting trends in the Forex Market, the release has historically been one of the most important reports out of the any country.
