Recession Predictors and Indicators
There is no reliable way to predict how and when a recession will occur. But, according to many economists, there are some generally accepted predictors that. when they occur together, may point to a possible recession. First, asset prices will begin to decline. This includes home prices and other financial assets like stocks. Another possible predictor is unemployment; generally speaking, a three-month change in the unemployment rate and initial
jobless claims will point to a recession. An
inverted yield curve is also another predictor. When long-term yields fall below the short term ones (the 10-year vs. the 3-month Treasury securities), a recession will occur. Conversely, a positively sloped curve (in the opposite direction) will signal inflationary growth. Since 1970, all the recessions that have taken place in the United States up through 2017 have followed an inverted yield curve.
Aside from two consecutive quarters of GDP decline, economists assess several metrics to determine whether a recession is imminent or already taking place. These indicators are divided into two categories:
leading indicators and
lagging indicators. Leading indicators materialize before a recession is officially declared. Perhaps the most common leading indicator is contraction in the stock market. Declines in broad stock indices, such as the Dow Jones Industrial Average (DJIA) and Standard & Poor's (S&P) 500 index, often appear several months before a recession takes shape. This was the case in 2007 in the United States, when the market began declining in August, four months ahead of the official recession in December 2007.
Lagging indicators of a recession include the unemployment rate. Though the Great Recession began in December 2007, the unemployment rate still indicated full employment — a rate of 5 percent or lower — four months later. The unemployment rate began declining in May 2008 and did not recover until several months after the recession ended in June 2009.
