Weekly report about natural gas storage change in the USA.

The actual inventories of crude oil, gasoline, and distillate, such as jet fuel, as reported on a weekly basis. The numbers are watched closely by the energy markets, and if the results differ greatly from the expected inventory levels, the market can react strongly. The inventory data can be skewed by holidays and seasonal factors. Weekly data can be unreliable and should be viewed as a part of longer-term trends, so a four-week moving average may be more useful.

National Consumer Price Index (CPI) is the key gauge for inflation in Japan. Simply put, inflation reflects a decline in the purchasing power of the Yen, where each Yen buys fewer goods and services. In terms of measuring inflation, CPI is the most obvious way to quantify changes in purchasing power. The report tracks changes in the price of a basket of goods and services that a typical Japanese household might purchase. An increase in the index indicates that it takes more Yen to purchase this same set of basic consumer items.

Markets will typically pay more attention to "CPI excluding Fresh Food," because it excludes volatile food prices that can distort overall CPI. The headline figure for CPI is the percentage change in the index on a month to month or year to year basis.

As the most important indicator of inflation, CPI figures are closely followed by the Bank of Japan. Rising Consumer Prices may prompt the BoJ to raise interest rates in order to manage inflation and slow economic growth. Higher interest rates make holding the Yen more attractive to foreign investors, and this higher level of demand will place upward pressure on the value of the Yen.

The difference between the total value of exports and the total value of imports. A positive figure indicates a trade surplus while a negative value represents a trade deficit. Because Japan 's economy is highly export-led, trade data can give critical insight into developments in Japan 's economy and changes into foreign exchange rates.

A surplus reflects capital flowing into Japan in exchange for Japanese exports, and a deficit means that capital is flowing out of Japan as imports are purchased in larger volumes by Japanese consumers. A trade surplus will act as an appreciating weight on the Yen, whereas a trade deficit will place downward pressure on the Yen's value.

Details in the Trade Balance report itself give useful insight into changing trends regarding Japanese trade. Such developments are especially important for the country, which is an export-oriented economy that has historically experienced large trade surpluses. Any affect on this could have dramatic affect on the domestic economy.

The headline figure for trade balance is expressed in millions of Yen and usually accompanied by a year-on-year percentage change figure.

Fixed asset investment, or FAI, is a measure of capital spending. It refers to any investment within the measurement period in physical assets, such as real estate infrastructure, machinery, etc. that are held for more than one year. FAI can be a good indicator for how much investment is occurring in a country or region, but it is not a direct contributor to GDP.

Gauge for goods sold at retail outlets in the past month. Retail Sales is a leading indicator for the economy. Rising consumer spending fuels economic growth, confirms signals from consumer confidence, and may spark inflationary pressures.

The headline figure is expressed as the percentage change from the same month last year.

The percentage of individuals in the labor force who are without a job but actively seeking one. A higher Unemployment Rate is generally a drain on the economy. Not only does it mean that resources are not being fully utilized, but it also results in lower consumer spending as there are fewer workers receiving paychecks.

Note: The unemployment rate generally moves slowly, so changes of only a few tenths of a percent are still considered significant. Also note that the unemployment rate does not account for discouraged workers. Therefore, in an economically depressed environment, such as that which occurred in Cold War era East Germany, the Unemployment Rate may not accurately reflect the extent of problems.
