Shares mostly rose in early Wednesday trading, echoing the rally on Wall Street that came as oil prices eased on hopes that the United States and Iran may resume talks.
European stocks were mostly steady on Wednesday as investors weighed signals from Washington that a diplomatic breakthrough in the Iran war could be imminent.
The pan-European Stoxx 600 had ticked down 0.1%, Germany's Dax edged 0.11% higher and the FTSE 100 climbed 0.11%. The CAC 40 in France fell by a slightly greater margin, at 0.65%.
US President Donald Trump said fresh talks between Washington and Tehran "could be happening over the next two days" in Islamabad, signalling a possible diplomatic breakthrough, and added that the war was "very close to over" — despite continued uncertainty over key sticking points in negotiations.
Asian markets were broadly higher.
Japan's Nikkei 225 gained 0.5%, South Korea's Kospi jumped 3.0% and Hong Kong's Hang Seng edged up 0.7%.
The Shanghai Composite added 0.2%, while Australia's S&P/ASX 200 was little changed, up less than 0.1%.
On Wall Street, the S&P 500 added 1.2% to its gains from the previous day, and the index at the heart of many 401(k) accounts is now just 0.2% below its record set in January.
The Dow Jones Industrial Average rose 317 points, or 0.7%, while the Nasdaq Composite climbed 2%.
On Wednesday, benchmark US crude inched up by 1 cent to $91.29 a barrel.
Brent crude added 48 cents to $95.27, or less than 1%, after falling 4.6% the previous day. While that is still above its roughly $70 level from before the war began in late February, it remains well below the peak of $119.
Lower oil prices help reduce costs for businesses across the economy. However, some analysts noted that the war is still ongoing, warning that the optimism may prove unfounded.
"The counterintuitive decline in crude appears driven by growing hopes that a second round of peace talks between Washington and Tehran could soon materialise, after the first attempt fizzled out," said Tim Waterer, chief market analyst at KCM Trade.
"Traders are clearly choosing to price in the possibility of de-escalation rather than the immediate reality of restricted flows," he added.
Asian nations depend on access to the Strait of Hormuz, a narrow waterway that is the main route for crude oil produced in the Persian Gulf to reach customers worldwide. Disruptions there have kept oil off the global market, driving up prices.
Global inflation this year is expected to accelerate to 4.4% from 4.1% in 2025, according to the International Monetary Fund, which had previously forecast a slowdown to 3.8%.
The IMF also downgraded its forecast for global economic growth to 3.1% this year, from 3.3% projected in January.
Overall, the S&P 500 rose 81.14 points to 6,967.38. The Dow Jones Industrial Average gained 317.74 points to 48,535.99, while the Nasdaq Composite climbed 455.35 points to 23,639.08.
In the bond market, Treasury yields eased as falling oil prices reduced inflationary pressure. The yield on the 10-year Treasury fell to 4.25% from 4.30% late Monday.
In currency trading, the US dollar edged up to 159.03 Japanese yen from 158.79 yen. The euro stood at $1.1780, down from $1.1797.
US stocks climbed to the brink of a record high on Tuesday, while oil prices eased as hopes grew that Washington and Tehran may resume talks to end their war.
The S&P 500 rose 1.2%, leaving it just 0.2% below its January peak. The Dow Jones Industrial Average gained 0.7%, while the Nasdaq Composite jumped 2%, tracking broader global market gains.
Investors are betting that renewed diplomacy could prevent a prolonged surge in oil prices and inflation, allowing focus to return to corporate earnings.
Brent crude for June delivery fell 4.6% to $94.79, down from recent highs, though still above pre-war levels.
However, volatility remains high, with markets sensitive to developments around the Strait of Hormuz, a key route for global oil supply.
