A battle has broken out in bond markets, pitting investors’ fears of inflation against their concerns about slowing growth. The result is heightened volatility and a cloudy outlook for other investments.

In just one 15-hour stretch on Thursday, the yield on the benchmark 10-year U.S. Treasury note started at around 3.2%, climbed to roughly 3.5% and then fell to 3.18%, charting a gain and a loss that in a different time could each have taken weeks. Yields rise when bond prices fall.
