Tokyo, Apr 28 (AP) Markets on Wall Street were mixed in early trading Tuesday, and oil prices soared as diplomatic efforts to end the Iran war appeared destined to stall again.

Futures for the S&P 500 slipped 0.6 per cent while futures for the Dow Jones Industrial Average gained 0.2 per cent. Nasdaq futures sank 1.1 per cent.

The Trump administration seemed unlikely to accept Iran's offer to end the war and reopen the Strait of Hormuz on the condition that the US lifts its blockade on the country's ports.

The proposal would postpone discussions on the Islamic Republic's nuclear program, something that US Secretary of State Marco Rubio appeared to rule out in a TV interview on Monday. The White House said US President Donald Trump's national security team discussed the offer and Trump would address it later.

The lack of progress to end the Middle East conflict has kept oil and gas prices elevated in recent months.

The price for a barrel of Brent crude to be delivered in July, the most heavily traded futures contract, rose USD 3.26 to USD 104.95 per barrel.

Brent prices were at about USD 70 per barrel before the war and have briefly shot to nearly USD 120. Benchmark US crude for delivery in July added USD 4.47 to USD 100.84 a barrel. Meanwhile, the average price of a gallon of gasoline in the US reached USD 4.18 on Tuesday, the most since 2022, according to the auto club AAA.

Rising oil prices have lifted energy companies since the onset of the Iran war in late February. On Tuesday, British energy giant BP reported that its profit more than doubled from a year ago, sending its shares up 3.2 per cent.

American oil companies ExxonMobil, ConocoPhillips and Chevron all rose by more than 2 per cent in premarket. All three of those companies report earnings this week.

The Federal Reserve meets on Wednesday to decide where to take interest rates. In light of the war in Iran and rising energy costs, most experts expect the Fed to stand pat, neither raising nor cutting its benchmark lending rate out of fear that it could exacerbate inflation.

Also, on Wednesday, the Senate Banking Committee will vote on whether to confirm Trump's nominee, Kevin Warsh, to succeed Fed Chair Jerome Powell. The committee is expected to approve Warsh, sending his nomination to the full Senate.

In Asia, Japan's benchmark Nikkei 225 fell 1.0 per cent to finish at 59,917.46 after the central bank opted to keep its key interest rate unchanged at 0.75 per cent.

The Bank of Japan said that while the economy was still growing moderately, it was expected to slow as the war pushes crude oil and other products higher. The vote by the monetary policy board at 6-3 was not unanimous. Pressures have been growing for Japan to gradually raise interest rates after keeping them near or below zero for years to combat deflation.

“There are various risks to the outlook," it said in a statement. “For the time being, it is necessary to pay particular attention to the impact of the future course of the situation in the Middle East.” Elsewhere in Asia, South Korea's Kospi edged up 0.4 per cent to 6,641.02.

Hong Kong's Hang Seng dipped nearly 1.0 per cent to 25,679.78, while the Shanghai Composite shed 0.2 per cent to 4,078.64.

Australia's S&P/ASX 200 lost 0.6 per cent to 8,710.70.

In Europe at midday, France's CAC 40 fell 0.3 per cent, while the German DAX lost 0.4 per cent. Britain's FTSE 100 was virtually unchanged. (AP) SKS SKS
