Press conference of the BoJ.

The Bank of Japan Policy Board meets once a month for two days to discuss economic developments inside and outside of the country. The culmination of the meeting is the announcement of any adjustments to interest rates or other aspects of monetary policy.

Like any central bank, the BOJ is tasked with ensuring price stability while taking into account economic growth, employment, and recommendations from the elected government. With this goal in mind, a "Guideline for Money Market Operations" is established at each meeting. Changes in the rate have far-reaching consequences, affecting consumer loans, mortgages, bonds and the exchange rate of the Yen. The statement is the Bank of Japan's collective outlook on the economy as well as a source for clues on future monetary policy decisions. When it comes to interest rates, the future direction of rates is usually far more important than its current rate.

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 headline inflation gauge for New Zealand.

A comprehensive measure of a New Zealand 's overall production and consumption of goods and services. GDP serves as one of the primary measures of overall economic well-being. Economic expansion, indicated by a growing GDP, raises concerns about inflationary pressure.

GDP calculates the total market value of goods and services produced in New Zealand within a given period after deducting the cost of goods and services used up in the process of production. Therefore, GDP excludes intermediate goods and services and considers final aggregates only. It is calculated as:

GDP = C + I + G + (EX - IM)

where

C = private consumption
I = private investment
G = government expenditure
EX = exports of goods and services
IM = imports of goods and services

The headline figures for GDP are the percentage growth rate from the previous quarter and the annualized percentage change in GDP. These are the preliminary figures, and are usually revised every following month.

Comprehensive measure of how much consumers spend each month, counting expenditures on durable goods, consumer products, and services. Personal Consumption is a comprehensive measure of GDP; consequently the figure is watched as an indicator for economic trends. Spending also has direct affect on inflationary pressures.

A healthy Personal Spending figure means that consumers are buying goods and services, fueling the economy and spurring output growth. The report is particularly valued for forecasting inflationary pressures. Taken in excess these high levels of consumption and production may lead to an overall increase in prices. Indeed, the Fed uses a measure of inflation derived from the PCE as their primary gauge of inflation.

On the other hand, persistently low Personal Spending may result in decreasing levels of output and an economic downturn.

Because income is either spent or saved, Personal Spending (when reported as a percent of income rather than the headline percent change) has an inverse relationship to personal saving. Economists watch the growth of Personal Spending in relation to income and saving to determine if consumers are living beyond their means, which would influence levels of borrowing and future consumption.

The PCE figure is released in headlines as a percent change from the previous month.

Core Personal Consumption Expenditure
Volatile items like food and energy can fluctuate widely due to seasonal and non-systemic factors. In order to provide a less erratic picture of Personal Consumption, food and energy items are excluded in the PCE core report.

The headline figure of PCE is expressed in percentage change in spending for the quarter.

Note: The Personal Consumption Expenditure figure is reported with the Personal Income and Outlays figure.
