US Treasury Yields Hit 17-Year High as Oil Prices Fuel Inflation Fears

The benchmark yield retreated from its morning peak to close at 4.97% according to official Treasury par-yield data, yet the brief breach of the 5% threshold intensified market anxiety. Pressure on bonds intensified as Brent crude prices climbed toward $110 a barrel following supply concerns linked to attacks on Saudi Arabian infrastructure. The resulting energy price volatility has left analysts questioning if current inflationary pressures will force a more aggressive stance from the Federal Reserve during its two-day policy meeting concluding Wednesday.

Equity markets reacted sharply to the dual headwinds of rising yields and cooling sentiment toward artificial intelligence. While the Nasdaq Composite slipped 0.56%, the Philadelphia Semiconductor Index faced a steeper 5.9% decline. This selloff in AI-linked stocks, including Nvidia and Broadcom, followed cautionary comments from industry leaders regarding the pace of advanced system development. As the Federal Reserve prepares its policy statement, market participants remain focused on whether the current 3.50%–3.75% federal funds range will be hiked by 25 basis points, a move currently priced in by approximately 93% of market participants according to CME FedWatch data.
