NEW YORK (Reuters) — As U.S. inflation worries grow, some investors are preparing for the 10-year U.S. Treasury yield to breach a 16-year high of 5% hit last October. Bond yields, which move inversely to prices, have climbed in recent weeks as signs of persistent inflation erode expectations for how deeply the Federal Reserve will be able to cut interest rates without further fueling consumer prices. The yield on the benchmark 10-year note is up 80 basis points this year and last stood at 4.70%, a five-month high. Many investors are betting further weakness lies ahead for bonds.
