US equities posted their strongest daily performance in six weeks Thursday. The rally followed a decline in crude oil prices and a reduction in Treasury yields.

The Standard & Poor’s 500 index rose 1.1% on Thursday. This marked the second positive session for the benchmark in the last nine trading days. The Dow Jones Industrial Average added 316 points, representing a 0.6% increase. The Nasdaq Composite climbed 1.7%, leading the broad market recovery.

Brent crude oil settled at $104.82 per barrel, down 1% from previous levels. This drop eased inflationary pressures that had weighed on equity valuations. The 10-year Treasury yield fell to 4.93% from 5.01% late Wednesday. Lower borrowing costs reduced the opportunity cost for holding stocks versus bonds.

Federal Reserve Hike Shapes Market Sentiment

The Federal Reserve raised the federal funds rate by 0.25% on Wednesday. This was the first increase in more than three years. Officials signaled a potential additional hike later this year to curb inflation. Chairman Kevin Warsh cited a strengthening economy and geopolitical risks, specifically the war in Iran, as drivers for the decision.

Market reaction to the rate hike was mixed initially. Stocks dipped sharply after the announcement before recovering gains by the close. Investors interpreted the move as a commitment to returning inflation to the 2% target. This stance was viewed as independent of political pressure for lower rates.

Sector Performance Driven by AI and Housing

Artificial intelligence stocks rebounded from a previous global slide. Nvidia shares increased by 2.5% during the session. Advanced Micro Devices rose 6.4%, outperforming the broader market. This recovery occurred despite new reports of safety concerns in AI models by OpenAI.

Homebuilder stocks also advanced despite weak new housing starts data. The sector had been pressured by the 10-year Treasury yield topping 5% earlier in the week. The drop in yields to 4.93% provided immediate relief to mortgage-sensitive equities. Economic indicators, including lower unemployment claims, suggested resilience against higher interest rates.

Oil Supply Risks Remain Elevated

Brent crude prices remain significantly above the $72 per barrel level seen earlier this summer. The current price reflects ongoing supply constraints from the conflict in the Middle East. Warsh noted that geopolitical instability could push prices higher, sustaining inflation risks. The market remains sensitive to any further disruptions in oil flows.

According to GN auto markets/bonds: bond yields, the decline in yields was a key factor in the equity rally. Higher yields typically reduce the net present value of future corporate earnings. The recent easing provided a necessary buffer for risk assets. Traders are now monitoring whether this trend sustains through the next Fed meeting.
