Benchmark 10-year Treasury yields hit the key psychological level of 5% on Monday for the first time since October 2023 ahead of this week’s Federal Reserve meeting, at which the U.S. central bank is widely expected to raise interest rates.The milestone is a threshold that analysts say could ripple through the U.S. economy and threaten the bull market in stocks by denting the relative appeal of U.S. equities. “It’s definitely a key psychological level. If you talk to investors, a lot of times they have those rounded numbers that they’re saying, ‘if we hit X level, that’s where I find it attractive, that’s where I buy the dip’,” said Molly Brooks, U.S. rates strategist at TD Securities
