The yield on U.S. inflation-adjusted government bonds has risen to its highest level in over a year, as a combination of rising oil prices and persistent economic strength has reignited market speculation that the Federal Reserve may begin raising interest rates in the coming months.

The yield on the 10-year Treasury Inflation-Protected Security (TIPS) climbed to approximately 2.3% on Wednesday, marking its highest point since April 2025. This increase in the so-called real yield enhances the appeal of the U.S. dollar while simultaneously raising the opportunity cost of holding non-yielding assets like gold and cryptocurrencies, thereby putting downward pressure on those assets.

This market movement reflects investor conviction that a resilient U.S. economy, bolstered by the artificial intelligence investment boom, will persuade Federal Reserve officials that the central bank can tighten monetary policy without derailing growth. Traders increased their bets on a Fed rate hike by October on Wednesday, as renewed escalation in U.S.-Iran tensions pushed oil prices higher and stoked inflation concerns.

Gennadiy Goldberg, head of U.S. rates strategy at TD Securities, commented, "The rise in real rates is being driven by solid growth expectations alongside market worries that the Fed may need to tighten policy further in the context of escalating Middle East conflict."
