Bessent's bond rescue fades, Walmart spooks Wall Street

US stocks had their worst day in three weeks, and the selling got heavier into the close. The Dow Jones Industrial Average finished down 703.84 points, or 1.3%, at 52,759.21, the S&P 500 fell 0.9% to 7,641.16, and the Nasdaq composite lost 1.0% to 26,067.17. Walmart, down about 9% after its earnings report, was the single biggest weight on all three.

Two separate stories drove the day, and both of them run through the bond market.

The first was the collapse of a rescue attempt. On Wednesday the Treasury Department said it would more than double its buybacks of 10, 20 and 30 year government debt, meaning it would go into the open market and purchase back bonds it had already issued. The logic is supply and demand. If there are fewer government bonds sloshing around, buyers do not have to be tempted with as high an interest rate, and that interest rate, called the yield, is the price the government pays to borrow. Stocks liked it for about a day. By Thursday the 30 year yield was back up to 5.26% and the 10 year to 4.71%, because investors concluded that buying back bonds does not touch the underlying problem, which is that the government is borrowing on an enormous scale and inflation has not gone away. The national debt passed $40 trillion this week.

The second push came from oil and, oddly, from good news. Brent crude, the international oil benchmark, rose 1.9% to $93.35 a barrel on worries that a confrontation with Iran could disrupt shipping through the Persian Gulf. At the same time, fewer Americans filed for unemployment benefits than economists expected and mid Atlantic factory activity came in stronger than forecast. Costlier energy feeds straight into inflation, and an economy that refuses to cool gives the Federal Reserve less reason to cut interest rates, so both readings pushed yields up rather than down. Rising yields hit stocks through a fairly mechanical channel: when perfectly safe government bonds pay 5%, investors demand more from riskier stocks to make the risk worth taking, and they place less value today on profits a company might earn many years from now. That math punishes expensive fast growing companies hardest, which is why the Nasdaq keeps getting caught in these moves.

Then there was Walmart, which is a story about the shopper rather than about bonds. Walmart beat expectations on both profit and revenue and raised its outlook for the year, and the stock fell anyway, because comparable sales at its US stores grew just 2.6% against the 3.7% analysts wanted, the slowest pace since 2020. The company's finance chief said gasoline above $4 a gallon has a psychological effect that pushes customers into making trade offs. Because Walmart sells to almost everyone, that comment gets read as a thermometer for the entire American consumer, so the drop was less about one retailer's quarter than about the market marking down its view of household spending. Advance Auto Parts fell 23.1% the same day, with its chief executive pointing to tighter household budgets, which is the same sentence in different words.
