Shares were mixed Tuesday in Asia after the U.S. military said it carried out what it called “self-defense” strikes in southern Iran, including on missile launch sites and boats placing mines.
The attacks came even as President Donald Trump said on social media that negotiations on ending the war were “proceeding nicely.”
U.S. futures jumped. Oil prices were mixed, with Brent crude trading below $95 a barrel.
The U.S. military said the strikes Monday were done “to protect our troops from threats posed by Iranian forces.” It said it used restraint due to the ceasefire with Iran, which gave no official response. Further details were not immediately available, including more specifics on threats from Iran and what this means for negotiations.
With the status of peace talks with Iran unclear, markets have been swayed by various developments and comments by Trump.
“Markets are behaving as though a full Iran breakthrough already exists, even though the hardest parts of the negotiation remain unresolved,” Stephen Innes of SPI Asset Management wrote in a commentary. “Washington continues to signal optimism, while Tehran insists no agreement is imminent.”
Tokyo’s Nikkei 225 lost 0.4% to 64,897.64, falling back from an all-time high close on Monday.
In Hong Kong, the Hang Seng index gained 0.3% to 25,668.55, while the Shanghai Composite index shed 0.7% to 4,122.87.
South Korea’s Kospi jumped 2.9% to 8,075.71, catching up after markets were closed Monday for a holiday.
The S&P/ASX 200 in Australia lost 0.4% to 8,653.80.
The futures for the S&P 500 and the Dow Jones Industrial Average surged 0.6% early Tuesday.
Benchmark U.S. crude oil declined $5.01 or more than 4%, to $91.59 a barrel. Brent crude, the international standard, gained $1.57 to $94.99 a barrel after falling nearly $5 on Monday.
U.S. markets were closed on Monday for the Memorial Day holiday, while European shares advanced.
France’s CAC 40 gained 1.1% and the German DAX rose 1.0%. Britain’s FTSE 100 added 0.2%. Trading will be closed in the U.S. for the Memorial Day holiday.
The gains followed signals of progress toward a peace deal. Regional officials said Sunday that the United States was close to reaching an agreement with Iran to end the war, reopen the Strait of Hormuz and see Iran give up its stockpile of highly enriched uranium,
Reopening the Strait of Hormuz will help decide the direction of oil prices. Its closure due to the war has prevented oil tankers from exiting the Persian Gulf and delivering crude to customers worldwide. Japan, for instance, imports almost all its oil, most of it through the strait.
In other dealings early Tuesday, the U.S. dollar rose to 158.94 Japanese yen from 158.91 yen. The euro cost $1.1634, down from $1.1645.
