Inflation forecasting is complex and risky, with short-term forecasts relying on historical data and technical analysis, while long-term forecasts consider global economic factors. The Consumer Price Index (CPI) is commonly used to measure inflation. Seasonal variations and unpredictable events make inflation forecasts uncertain.
Determining inflation forecasts is a complicated procedure on which not all economists agree. The Consumer Price Index (CPI) is often used as a measure of inflation. In general, forecasts are given in the short and long term. Short-term forecasts tend to depend on historical inflation rates, while long-term forecasts consider other economic factors. Inflation forecasts are inherently risky, as many events that affect the rate of inflation are essentially unpredictable.
Before forecasting inflation, a method for measuring inflation must be established. In the United States, the CPI is the most common measure used. The CPI works by tracking a variety of basic goods and services, such as food and medicine. Each item in the calculation is weighted based on its impact on the cost of living. In this way, the CPI can track how these costs change over time, a common definition of inflation.
The short term is often considered several months to a year, while the long term is ten years or more. In the short term, forecasts could largely focus on technical analysis techniques. Technical analysis uses past data, in this case past CPI inflation rate data, without much speculation about future events. More recent data, such as data from the past few months, is generally weighted more than data from the distant past.
Proponents of technical analysis as a means of determining inflation forecasts cite the unreliability of other methods. They claim that historical inflation forecasts that attempted to incorporate economic trends such as employment have missed their predictions. They argue that momentum in an economy can have a major effect in the short term, and that this momentum is best detected in the trend of inflation itself.
Inflation forecasts for more than a few months can benefit from adjusting for seasonal variations. Historically, inflation rates in the United States have been lower from May to July and from November to December than during other months of the year. This has been a very regular cycle, so economists are very confident that it will repeat itself in the future. Forecasts that take this into account are said to be seasonally adjusted.
Long-term inflation forecasts tend to use fundamental analysis methods. This involves broad consideration of factors in the global economy and geopolitical landscape. For example, the power of large central banks can be significant for inflation rates. Furthermore, inflation is highly dependent on the political stability of an economy.
There will always be uncertainty with inflation forecasts because certain events are beyond the predictive reach of economists. Natural disasters, for example, can cause the prices of basic building products to rise. Similarly, stock market crashes are virtually unpredictable. Finally, a large holder of foreign exchange reserves, such as China, can suddenly release money into the economy, which has the effect of expanding the money supply and increasing inflation. With these possibilities in mind, inflation forecasts are best viewed as practical guidelines in the event world events go as planned.
