European stocks and Wall Street futures rebounded Wednesday as investors watched diplomatic efforts to end Russia's attack on Ukraine, while Asian markets sank after Chinese inflation accelerated. Already high oil prices added more than $1 per barrel following President Joe Biden's ban on imports of Russian crude. London and Frankfurt opened higher. Shanghai, Tokyo and Hong Kong declined amid enduring unease about the war's global impact.

On Monday, it closed 20% below its record high.

Brent crude, the basis for international oil prices, gained $2.42 to $130.40 per barrel in London. It advanced $4.77 the previous session to $127.98. Commodities markets have been roiled because Russia is the No. 2 oil exporter and the No. 3 supplier of nickel, which is used in electric car batteries, stainless steel and other products. Russia and Ukraine also are among the biggest global sellers of wheat.

The exchange said it did not expect to resume trading before Friday and was considering imposing limits on price fluctuations when it does. A major Chinese producer of nickel and stainless steel, Tsingshan Group, faces potential losses of billions of dollars on futures contracts, The Asian Wall Street Journal and Bloomberg News reported. A woman who answered the phone at Tsingshan's headquarters hung up when told a reporter was calling. On Tuesday, Biden announced the United States would block imports of Russian crude to punish Putin for attacking Ukraine. Biden said he acted in consultation with European allies but acknowledged they are more dependent on Russian oil and gas and might not be able to make similar moves immediately. Biden said he hopes to limit the pain for Americans but acknowledged the ban will push up gasoline prices. “Defending freedom is going to cost us as well,” he said. Before the invasion of Ukraine, financial markets already were uneasy about the global outlook as the Federal Reserve and other central banks prepare to try to cool inflation by withdrawing ultra-low interest rates and other stimulus. In currency markets, the dollar advanced to 115.79 yen from Tuesday's 115.74 yen. The euro gained to $1.0951 from $1.0908.
