The Federal Reserve faces a pivotal decision on March 22, 2023: whether to continue its aggressive fight against inflation or put it on hold.

Making another big interest rate hike would risk exacerbating the global banking turmoil sparked by Silicon Valley Bank’s failure on March 10. Raising rates too little, or not at all as some are calling for, could not only lead to a resurgence in inflation, but it could cause investors to worry that the Fed believes the situation is even worse than they thought – resulting in more panic.

What’s a central banker to do?

As a finance scholar, I have studied the close link between Fed policy and financial markets. Let me just say I would not want to be a Fed policymaker right now.

When the Fed starts hiking rates, it typically keeps at it until something breaks.

The U.S. central bank began its rate-hiking campaign early last year as inflation began to surge. After initially mistakenly calling inflation “transitory,” the Fed kicked into high gear and raised rates eight times from just 0.25% in early 2022 to 4.75% in February 2023. This is the fastest pace of rate increases since the early 1980s – and the Fed is not done yet.

Consumer prices were up 6% in February from a year earlier. While that’s down from a peak annual rate of 9% in June 2022, it’s still significantly above the Fed’s 2% inflation target.

But then something broke. Seemingly out of nowhere, Silicon Valley Bank, followed by Signature Bank, collapsed virtually overnight. They had over US$300 billion in assets between them and became the second- and third-largest banks to fail in U.S. history.

Panic quickly spread to other regional lenders, such as First Republic, and upset markets globally, raising the prospect of even bigger and more widespread bank failures. Even a $30 billion rescue of First Republic by its much larger peers, including JPMorgan Chase and Bank of America, failed to stem the growing unease.

If the Fed lifts interest rates more than markets expect – currently a 0.25 percentage point increase – it could prompt further anxiety. My research shows that interest rate changes have a much bigger effect on the stock market in bear markets – when there’s a prolonged decline in stock prices, as the U.S. is experiencing now – than in good times.
