Pressure from the bond market hits a new level, and US stocks slide on worries about inflation

NEW YORK (AP) — Pressure from the U.S. bond market hit a new level on Wall Street Wednesday after a surprisingly strong report on the economy raised worries about inflation, while oil prices halted their slide. The squeeze caused U.S. stocks to sink.

The S&P 500 fell 0.8% after finishing the prior day just 0.4% below its record set last month. The Dow Jones Industrial Average dropped 352 points, or 0.7%, while the Nasdaq composite sank 1.1% from its own all-time high.

Stocks wilted after the yield on the 10-year Treasury jumped to 5.10% from 4.96% late Tuesday, which is a considerable move for the bond market. High yields undercut prices for stocks and other investments, while also slowing the economy by making it more expensive for everyone to borrow money.

Wednesday’s jump briefly sent the 10-year yield near 5.14%, back to where it was in 2007 before the global financial crisis caused yields to crater. Yields have been climbing since bottoming out in the COVID pandemic, and they’ve accelerated recently because of worries about high inflation, the U.S. government’s heavy debt and other concerns.

Worries about inflation got a jolt Wednesday morning after a preliminary report suggested growth in U.S. business activity surged to its strongest level in more than five years. That’s an encouraging signal, to be sure, but it indicates the economy may have plenty of fuel for more inflation.

The report also suggested costs for businesses are leaping at the fastest rate in four years, in part because of more expensive oil, according to Chris Williamson, chief business economist at S&P Global Market Intelligence. That could mean businesses will pass those higher costs onto their customers in coming months.

Oil prices are high because of worries that the war with Iran will keep oil bottled up in the Middle East for a long time.

The price for a barrel of Brent oil to be delivered in November rose 3.9% to $103.08 on Wednesday. That reversed a decline for Brent, which had been falling since it neared $110 last week. Talks are continuing with mediators between U.S. and Iranian officials, but nothing concrete has come from it yet.

Brent oil to be delivered in December, where most of the trading in the market has moved, rose 2.8% to $98.12 per barrel.

Even with its recent decline, the price for a barrel of Brent remains much higher than the roughly $72 it cost before the war with Iran began.

Inflation has remained so stubbornly high that the Federal Reserve raised its short-term interest rate last week for the first time in three years in hopes of slowing down increases in the cost of living.

Fed Gov. Michael Barr said in a speech on Wednesday that further hikes “are likely to be needed” to get inflation to the Fed’s 2% target. Traders now see better than a 50% probability that the Fed will hike its federal funds rate at each of its next two meetings, in October and December, according to data from CME Group.

So far, strong growth in profits for U.S. companies has helped support the U.S. stock market despite higher interest rates and more expensive oil.

KB Home became the latest to deliver a stronger profit for the latest quarter than analysts expected. But its stock nevertheless swung between losses and gains after the homebuilder’s executive chairman said conditions got even tougher for the industry over the last three months. It finished with a loss of 3%.

Potential customers are becoming more cautious because of higher mortgage rates caused by the rise in the 10-year Treasury yield. They also are feeling pressure from “geopolitical uncertainty and broader economic headwinds,” Jeffrey Mezger said.

General Mills likewise reported a stronger profit for the latest quarter than analysts expected. But the company behind the Cheerios and Progresso brands said it also expects growth this fiscal year to fall below its historical track record “driven by a continued challenging consumer backdrop,” and it did not raise its forecast for profit over the full fiscal year.

Its stock flipped between gains and losses before rising 1%.

All told, the S&P 500 fell 58.61 points to 7,706.03. The Dow dropped 352.10 to 51,511.59, and the Nasdaq composite sank 308.24 to 26,936.04.

In stock markets abroad, indexes slipped across much of Europe and Asia.

Stock indexes fell 1% in Hong Kong and 0.4% in Shanghai ahead of Chinese President Xi Jinping’s state visit to Washington, which is kicking off Wednesday.

The leaders are expected to attempt to steady fragile ties in their third meeting since Trump returned to the White House. That is despite the world’s two largest economies seeking the upper hand on artificial-intelligence developments and trade, while pushing for leverage in persistent hot spots like Iran and Taiwan.
