An economic calendar not only lists daily events, but the volatility levels attached to them. A volatility level refers to the likelihood that a specific event will impact the markets. Economic calendars usually have a three-scale volatility gauge. If an event has a level one volatility, it is not expected to significantly affect the markets. An event with a volatility level of two is expected to impact the markets moderately, depending on other factors (e.g. other market-moving events, political factors, news items, etc.). An event with a volatility level of three is expected to have a significant impact on the markets. Highly volatile events are often the most closely monitored. Below are some examples of level one, level two and level three events:
Volatility Level One • Current Account • Foreign Portfolio Investments • Bill Auction
Volatility Level Two • Purchasing Managers’ Index • Retail Sales • Industrial Production
Volatility Level Three • Monetary Policy Announcement • Consumer Price Index • Employment data (job growth, unemployment rate) Investors should also note that large, economically powerful countries usually have the biggest impact on the markets. In this case, an economic indicator released by a smaller country may not have the same impact as one released by a bigger country. For example, the
consumer price index of
Greece is unlikely to impact the markets, and some calendars will have it listed as a level one event. By contrast, consumer price index data from the United States or
Eurozone will have the biggest impact on the markets. Countries and economic regions that tend to impact the markets the most are the United States, Eurozone, Japan and the United Kingdom.
