Stock futures slid in Asia on Monday as investors dug in for a protracted Gulf conflict that already has oil prices heading for a record monthly rise, bringing a spike in inflation and the risk of recession to much of the globe.
Pakistan said on Sunday it was preparing to host "meaningful talks" to end the conflict over Iran in coming days even though Tehran earlier accused Washington of preparing a land assault as the U.S. military sends more troops to the region.
Yemen's Iran-aligned Houthis also launched their first attacks on Israel since the start of the conflict.
"Iran's control of the Strait of Hormuz, capacity to disrupt global energy and food markets, and sustained missile and drone capabilities give it little incentive to concede, pressuring the U.S. to escalate," said Madison Cartwright, senior geo-economics analyst at CBA.
"We expect the war to run at least into June, with the risk tilted to a longer conflict."
The clampdown on the Strait has sent prices for oil, gas, fertiliser, plastic and aluminium surging, along with fuel for planes and shipping. Prices for food, pharmaceuticals and petrochemical products are all set to rise.
That is bad news for Asia, as much of the region is highly dependent on energy from the Middle East. Futures for Japan's Nikkei were trading down at 50,870, pointing to a steep fall from Friday's close of 53,373 (.N225).
S&P 500 futures lost another 0.6%, while Nasdaq futures fell 0.7%.
Brent crude rose 2.4% to $115.33 a barrel, bringing its gains for the month to 59% and topping the jump that followed Iraq's invasion of Kuwait in 1990. U.S. crude climbed 3.0% to $102.52, making a monthly rise of 53%.
"The longer the Strait remains closed, the sharper the drawdown in buffer supplies that could spark dramatic increases in the price of crude oil, natural gas and other commodities," warned Bruce Kasman, global head of economics at JPMorgan.
"A scenario in which the Strait remains closed for an additional month would be consistent with oil prices rising towards $150/bbl and constraints on industrial consumers of energy supply."
The inflationary threat has led investors to revise up the outlook for interest rates almost everywhere. Markets now imply 12 basis points of tightening by the Federal Reserve this year, compared with 50 basis points of cuts a month ago.
Fed Chair Jerome Powell will have a chance to air his own views at an event later on Monday, and the influential head of the New York Fed, John Williams, is also talking.
Data on U.S. retail sales, manufacturing and payrolls this week will provide an update on how the economy is travelling. Jobs are seen rising 55,000 in March, after February's shock 92,000 drop, keeping unemployment at 4.4%.
In the European Union, figures on Tuesday are forecast to show annual inflation leaped to 2.7% in March, from 1.9% the month before, though core prices should be steadier.
The coming energy shock, combined with pressure on fiscal budgets from higher borrowing costs and the need for more defence spending, has slugged sovereign bond markets.
Ten-year U.S. Treasury yields are up roughly 47 basis points for the month so far at 4.428%, while two-year yields have climbed 54 basis points.
Heightened volatility in markets has tended to benefit the U.S. dollar as the world's most liquid currency. The United States is also a net energy exporter, giving it a relative advantage over Europe and much of Asia.
The dollar was trading a touch firmer early on Monday at 160.42 yen , having last week crossed the 160 barrier for the first time since July 2024 when Japan last intervened to prop up the currency.
The euro was stuck at $1.1492 , not far from the March trough of $1.1409.
In commodity markets, gold was little changed at $4,487 an ounce , having drawn scant support as a safe haven or as a hedge against inflation risks.
