U.S. stocks swung as oil prices kept climbing because of uncertainty about when the war with Iran could end. The S&P 500 fell 0.4% Monday and deepened its loss since the war began to pull 9.1% below its record.

The Dow Jones Industrial Average rose 0.1%, and the Nasdaq composite fell 0.7%. Caution was prevalent throughout markets. After jumping to an initial gain of 0.9%, the S&P 500 quickly erased nearly all of it before seesawing lower. Indexes rose in Europe but fell sharply in some Asian markets, while the price of U.S. oil topped $100 per barrel.

Kosovo struggles as Iran war drives up fuel prices

Kosovo is one of the Europe’s poorest countries and struggles with a steep rise in fuel prices caused by the Iran war. A company that produces potato chips and other snacks for domestic consumption and export says a price hike affects both planting and distribution.

Neighbors like Serbia, Hungary and Romania have imposed measures to mitigate effects of the crisis, but Kosovo’s government is yet to act. Kosovo’s economy has struggled since the country declared independence from Serbia in 2008 after a war.

Powell says Fed limited as energy prices spike

Federal Reserve Chair Jerome Powell says it’s important to closely monitor inflation amid a spike in energy prices from the Iran war as the average price for for gasoline nears $4 a gallon in the U.S. But he also said Monday, addressing students at Harvard University, that there isn’t a lot Fed policymakers could do.

New York Times accuses Pentagon of flouting order

A New York Times attorney claims the Pentagon has flouted a court order blocking it from enforcing a policy limiting news reporters’ access to the Defense Department’s headquarters.

U.S. District Judge Paul Friedman didn’t immediately rule from the bench on Monday after hearing a second round of arguments from lawyers for the newspaper and the government. The Times claims Pentagon officials implemented a revised press policy that circumvents a prior ruling by Friedman. The newspaper urged the judge to compel the government’s compliance with his March 20 order. In that ruling, Friedman said the Pentagon’s new credential policy violated journalists’ constitutional rights to free speech and due process.

Air Canada CEO to retire this year after criticism

Air Canada says CEO Michael Rousseau plans to retire. Rousseau had faced criticism over an English-only condolence message after a deadly crash this month at New York’s LaGuardia Airport.

The airline based in French-speaking Quebec said Monday that Rousseau told the board he will retire by the end of the third quarter. Two pilots died after an Air Canada Jazz flight from Montreal hit a fire truck on the runway. One pilot was a French-speaking Quebecer. Prime Minister Mark Carney and Quebec Premier Francois Legault criticized the airline CEO’s English-only message. Hundreds have complained to Canada’s language watchdog.
