The single biggest reason markets dropped so hard last year — interest rates

I recently wrote how the two biggest factors controlling the stock market are earnings and interest rates. I want to focus this article on interest rates because they played a very important role in the extreme market movements we saw over the past five months.

Many people are still wondering why the market dropped so hard in the fourth quarter of 2018. There were many factors involved such as the slowing earnings picture, the US/China trade war, hedge fund redemptions, and of course, interest rates. Looking back, I think the biggest reason was interest rates because the market was clearly telling us it could not handle the series of rate hikes that were coming.

How rate hikes can cripple an economy

In early October 2018, Federal Reserve Chairman Jerome Powell said he would be raising rates three times in the upcoming year. One has to step back and consider how this can really cripple an economy. Higher interest rates affect many areas such as corporate debt, business lending, auto loans, credit card payments, student loans, and of course the housing market via mortgage rates. You might not think it’s a big deal if one of these payments increases by $17 a month, but multiply that by hundreds of millions of people, and you can really see the domino effect. After all, consumer spending is 70% of the economy and higher rates takes away an enormous amount of money that would otherwise flow back into the system.

Let’s look back as to why Chairman Powell wanted to raise rates. The academic reason is that he was trying to fight inflation. In my view, this was a mistake because there was very little inflation out there proven by the fact that the December Consumer Price Index (CPI) actually went negative.

The “not so popular” reason is that the stock market has been rising steadily for years and gave us a cushion for higher rates. Very few people want to talk about this because they actually believe the Fed only looks at economic data and makes rate decisions independent of the stock market. If you believe this, then you don’t belong in this business. Of course, the Fed mostly looks at economic data when the stock market is stable, but if the market starts to tank, they throw all that out the window. Nevertheless, the stock market clearly told us in the fall of 2018 that it could not handle several rate hikes and we were on the verge of a Fed-induced recession.

The role of hedge funds

Another factor that very few people discuss is the amount of deleveraging that was done by hedge funds. Yes, they partially had to sell because of redemptions, but many of them took risk off to adjust for higher rates. For example, a $10 billion hedge fund might actually be working with two to four times that amount because they can borrow cheaply to increase both long and short exposure. Again, multiply that by the thousands of hedge funds that use this same strategy and you have another reason for the decline in late 2018. You can see proof of this in the 13F filings that came out in mid-February 2019. Almost every hedge fund I looked up reduced equity exposure, and many by more than 50%.
