Bonds Face Familiar Concerns
The exhibit below shows May returns for a sample of Morningstar analyst-rated ETFs that serve as proxies for major asset classes. Investors in a blended portfolio lost 0.93% last month, as U.S. bonds and foreign stocks weighed on returns.

Vanguard Total Bond Market ETF BND hampered the blended portfolio’s bond sleeve with a 1.16% loss in May. Against the backdrop of a then-unresolved U.S. debt ceiling, investors digested many of the same economic concerns that punished bonds in 2022. Initially, most market participants believed the interest-rate hike that the Federal Reserve greenlit in its May 3 meeting would mark the last for a while. But hotter-than-expected inflation and labor data emerged throughout the month, casting doubt on whether the Fed would pause rate hikes like it hinted it would.
