Federal Reserve Inflation Outlook Signals a Critical Warning for Investors

The Federal Reserve raised interest rates for the first time since July 2023 on Wednesday, and the S&P 500 (SNPINDEX: ^GSPC) immediately dropped. It rose again before the day was over, but it's been steadily declining over the past month since hitting a high in mid-August.

There are a number of reasons for the fall, and part of that has been the anticipation of rate hikes. The Fed's decision has a lot to do with the other reasons, including high inflation and rising oil prices, and none of these spell enthusiasm for the market. Here's how the inflation outlook and accompanying interest rates signal a warning for investors.

Why is there inflation?

The simple version is that rising oil prices increase production costs, leading to higher consumer prices. The artificial intelligence (AI) buildout is contributing as well; memory prices are skyrocketing as hyperscalers have an insatiable demand for scarce memory products, and Apple, for example, said it's going to raise some prices.

As inflation surges and prices go up, it's harder for shoppers to keep spending. The worry is that lower consumer spending will lead to sagging sales for many companies, and the market is pricing that in as the inflation outlook persists.

The resilient U.S. consumer

Inflation began to climb when the government provided stimulus payments early in the pandemic, and rate hikes brought it down. However, the annual inflation rate hasn't fallen to the target of 2%, which was the prevailing rate before the pandemic began. The Fed declined to raise rates in July, hoping the situation in Iran would resolve, but it hasn't, and inflation is creeping up again.

Part of the problem is the strong U.S. consumer, who's not backing down despite the higher prices. "There's been a pretty wide-ranging set of data, including the labor markets, that the economy has strengthened," Federal Reserve Chairman Kevin Warsh said at the Fed meeting on Wednesday. That gives the Fed more confidence that the economy can handle the rate hike without falling into a recession.

According to the latest dot plot, 16 of 18 participants penciled in another increase this year, with four expecting two more.

What to expect from the markets

Historically, the markets haven't performed well when inflation skyrockets and interest rates rise. Inflation impacts the economy as explained above, and high interest rates impact it separately. They make it harder for companies and individuals to borrow money, hindering economic growth.

As you can see in this chart, high interest rates coincided with the crashes in 2000, 2008, and 2020. This current bull market stands out as an exception -- so far.

Investors and economists alike had been hoping for lower rates before another crash. But take this as a warning for what might be coming next.
