Where Is The Fed's Ammo?

Economies expand and contract as part of a natural economic cycle… growth, boom, slowdown, recession, recovery… repeat . The magnitude of the ups and downs changes, but not the cycle itself.

Since, and including, the Great Depression of 1929, the U.S. has been through a total of 14 economic recessions – defined by the National Bureau of Economic Research (NBER) as “a significant decline in economic activity spread across the economy, lasting more than two quarters which is 6 months, normally visible in real gross domestic product (GDP), real income, employment, industrial production, and wholesale-retail sales”.

The average gap between these economic contractions has been just under five years. The U.S. emerged from the last recession in the quarter ending December 31, 2009 – which is nearly eight years ago.

The NBER subsequently determined that the U.S. “trough” (that is, the lowest point) in business activity occurred in June 2009. This marked the end of the “Great Recession” that began nearly a decade ago in December 2007, and at 18 months in duration. It was the longest recession since World War II.

The average “trough to trough” of U.S. economic cycles, dating all the way back to 1919, is a little over 5.3 years. If we look at the post-World War II era, it’s around 5.8 years.

As per the chart below, some of the more recent periods of economic expansion have been longer, leading to bigger gaps between economic troughs. But even if you take the average of the last seven cycles (i.e., starting in 1970), the average is still less than seven years between troughs.
