Yardeni Says Fed Cut Raises Odds of ‘Outright Melt-Up’ in Stocks

US stocks can soar to fresh highs thanks to the Federal Reserve’s aggressive half-point interest rate cut last week, but it also could cause inflation to resurface if central bankers don’t tread carefully, according to Wall Street strategist Ed Yardeni.

The latest policy decision lifted the odds of an “outright melt-up” in equity prices — like during the dot-com bubble when the S&P 500 Index roared 220% from 1995 to the end of the century — to 30% from 20%. He placed the chances of a bull market at 80%, while reserving a 20% probability for a 1970s-like scenario, when stock markets around the world were gripped by volatility due to inflation and geopolitical tensions.

But there’s a broader risk if things start running too hot.

“If they overheat the economy and create a bubble in the stock market, they’re creating some issues,” the founder of eponymous firm Yardeni Research Inc. said in an interview with Bloomberg Television Monday. He added that the Fed is ignoring the upcoming US presidential election, in which both candidates are proposing policies that could trigger inflation.
