Stocks bounce back as oil and yields retreat

What happened

Stocks recovered on Thursday, one day after the Federal Reserve raised interest rates and knocked the market down. The S&P 500 closed up 1.1% at 7,637.76, the Nasdaq Composite rose 1.7% to 26,418.30, and the Dow Jones Industrial Average added 0.6%, or about 316 points, to 51,778.04. Crude oil fell 1.3% to roughly $101 a barrel and the 10 year Treasury yield, which is the interest rate the US government pays to borrow money for ten years, eased about six hundredths of a percentage point to 4.95%.

Why it happened

Start with Wednesday, because Thursday only makes sense against it. The Fed raised its benchmark rate by a quarter of a percentage point to a target range of 3.75% to 4%, its first increase since July 2023, and the vote was unanimous. More important than the hike itself was the guidance, which is the Fed's own forecast of what it will do next: 16 of the 18 officials who submit projections expect at least one more increase this year. Fed Chair Kevin Warsh put the reason plainly, saying that inflation is too high and has been for too long. Stocks fell hard on that news.

Thursday reversed part of it, and the reason was not the Fed at all. It was oil. Crude has been trading above $100 a barrel because the war involving Iran has restricted shipping through the Strait of Hormuz, the narrow waterway that a large share of the world's oil passes through, and because Saudi Arabia closed a major pipeline. Expensive oil is not just a gas station problem. It raises the cost of shipping, manufacturing, and farming, so it pushes up the price of almost everything, which is a large part of why inflation has stayed stubborn and why the Fed feels it has to keep raising rates. When oil fell on Thursday, investors read it as a small reduction in the pressure that forces the Fed's hand.

That shows up in bonds first. The 10 year Treasury yield fell below 5%, which looks backwards after a rate hike, but the two are measuring different things. The Fed sets a rate for overnight borrowing between banks. The 10 year yield reflects what investors expect inflation and growth to look like over the whole decade ahead, and a central bank that is visibly willing to raise rates makes runaway inflation over that stretch less likely. Falling yields then lift stocks through simple arithmetic. A company's share price is the value today of profits it will earn in future years, and a lower interest rate means those future profits are discounted less, so they are worth more now. Companies whose profits sit furthest in the future gain the most, which is why the Nasdaq, heavy with technology names, outran the Dow.

Individual names moved for their own reasons. Generac, which makes backup generators, jumped roughly 20% after announcing a long term supply agreement with Amazon tied to data centers. CoreWeave fell nearly 4% after disclosing a $3 billion convertible bond offering, a sign investors are getting choosier about technology firms borrowing heavily to build artificial intelligence infrastructure.

What it means for you

Mortgages take their cue from the 10 year Treasury yield rather than from the Fed directly, so Thursday's small decline is a rounding error. With the yield near 5%, mortgage rates stay expensive, and the pattern worth watching is that the Fed now expects to raise rates further, which is a genuine change of regime from the cutting cycle of the past two years. If you have been waiting for rates to fall before buying or refinancing, the Fed just told you that it is not planning to help you this year.

Savers get the better end of it. The Fed's rate is the anchor for what banks pay on savings accounts and certificates of deposit, so a rising benchmark means those payouts drift up rather than down. Large banks tend to pass this through slowly and online banks quickly, so the gap between a neglected checking account and a high yield savings account is currently wide enough to be worth one afternoon of paperwork.

At the pump and the grocery store, do not read too much into one day. Oil falling 1.3% from above $100 leaves it far above the roughly $72 a barrel it traded at in late February, and that gap is the thing showing up in your fuel and food costs. On retirement accounts, a 1.1% day is pleasant and means nothing on its own. The pattern to notice instead is that for the first time in years the Fed is tightening rather than easing, and periods of rising rates have historically been choppier for stocks and kinder to cash. That is an argument for checking that your contributions are automatic, not for rearranging anything.

Tomorrow brings August industrial production figures and a speech from Fed Governor Michelle Bowman, which is the first chance to hear how another official reads the inflation picture Warsh described.
