NEW YORK >> Wall Street took another sharp swing today, this time back to rally mode, as stocks and Treasury yields rose even as oil prices continued to climb.

The S&P 500 rose 1.9%, putting it back into the green for the week, after Federal Reserve Chair Jerome Powell said he supports a more modest rise in interest rates this month than some investors had been fearing.

Other markets were also showing less fear from the prior day. Treasury yields recovered some of their sharp losses and gold receded. U.S. crude oil climbed to $110.60 per barrel, the highest level in more than a decade.

NEW YORK >> Wall Street took another sharp swing today, this time back to rally mode, as stocks and Treasury yields rose even as oil prices continued to climb.

The S&P 500 was up 2.1% in afternoon trading after Federal Reserve Chair Jerome Powell said he supports a more modest rise in interest rates this month than some investors had feared. He also said he still expects inflation, which is at its highest level in 40 years, to moderate through the year.

The comments helped gains for stocks from earlier in the morning to accelerate. Other areas of the market were also showing less fear from the prior day, when worries about Russia’s invasion of Ukraine sent the S&P 500 tumbling 1.5% and prices soaring for all kinds of commodities.

Treasury yields jumped to recover some of their steep losses from the past week. Gold receded, and a measure of nervousness among stock investors on Wall Street eased after swinging sharply in recent days.

“We’ve seen wild swings, but not major changes in the indexes,” said Jeff Kleintop, chief global investment strategist at Charles Schwab. “Geopolitical conflicts can be very unsettling, but you don’t tend to get bear markets from these, just periods of volatility.”

Markets have been spinning wildly as investors try, sometimes blindly, to gauge how high Russia’s attack on Ukraine will push prices for oil, wheat and other commodities where the region is a major producer. On top of that are worries about what upcoming hikes in interest rates by the Federal Reserve and other central banks around the world will do to the economy and inflation.

The Fed’s Powell said in testimony to Congress that his central bank is set to raise its key interest rate for the first time since 2018. But he also said the attack on Ukraine may have muddied conditions, with its impact on the U.S. economy “highly uncertain,” adding that “we’re never on autopilot.”

The Fed is balancing a tightrope where it needs to raise interest rates enough to rein in the highest inflation in generations but not so much that it pushes the economy into a recession. All the while, higher interest rates tend to put downward pressure on stocks and most other investments.

The yield on the 10-year Treasury leaped to 1.86% from 1.72% late Tuesday, while the two-year Treasury surged to 1.50% from 1.31%. Yields, though, remain well below where they were before Russia’s invasion. The 10-year yield was above 2% last month, before it plunged as investors plowed into investments seen as safer amid worries about war.

The price of U.S. oil jumped another 6.2% to $109.80 per barrel, though it moderated after climbing as high as $112.51 in the morning for the first time since 2014. Brent crude, the international standard, rose 6.3% to $111.54 per barrel.

Leaders of OPEC and other major oil-producing countries decided today to stick with their plan to gradually increase oil production. The OPEC+ coalition of oil producers, made up of OPEC members led by Saudi Arabia and non-cartel members led by Russia, chose to increase oil production by 400,000 barrels per day in April.

The move follows a perhaps less impactful decision by the United States and other major governments in the International Energy Agency to release 60 million barrels from strategic reserves to boost supplies.

“Markets dismissed the notion that 60 million barrels of strategic reserves released will be consequential to the risks of Russian supply jeopardized,” Tan Boon Heng of Mizuho Bank said in a report. “Russia pumps more than that in just six days.”

In the stock market, all the uncertainty about oil prices and inflation has led to big swings not only by the day but also by the hour. Through this afternoon, the S&P 500 swung between gains of 0.4% and 2.2%.

The Dow Jones Industrial Average was 687 points higher, or 2.1%, at 33,985, as of 2 p.m. Eastern time. The Nasdaq composite was 1.7% higher.

More than 90% of stocks in the S&P 500 rose, with technology, financial and health care companies accounting for much of the rally. Energy stocks helped lead the way as they rode higher energy prices, with those in the S&P 500 up 2.8%. Bank stocks also were big gainers as higher longer-term interest rates can mean bigger profits for them making loans.

Ross Stores climbed 6.6% after it reported stronger profit for its latst quarter than analysts expected.

Ford jumped 8.1% after it said it was accelerating its transformation into an electric-vehicle company and split its EV and internal combustion operations into two individual businesses.

Stock markets around the world were mixed. France’s CAC 40 rose 1.6%, Germany’s DAX returned 0.7% and Japan’s Nikkei 225 fell 1.7%.

Russia’s central bank said stock trading on the Moscow exchange would remain closed today for a third day, though trading of currencies and precious metals would resume for the first time this week.

Late Tuesday, President Joe Biden announced he was joining U.S. allies in closing the country’s air space to Russian aircraft, the latest in a set of sanctions and other measures meant to isolate Russia.

But Biden also said in his annual State of the Union speech that he would try to cushion Americans against the impact of higher oil prices. “I will use every tool at our disposal to protect American businesses and consumers,” Biden said.
