European equities edged higher on Wednesday as a sixth consecutive decline in oil prices eased some pressure on inflation, while renewed enthusiasm for artificial intelligence lifted technology stocks across global markets.
The gains came as investors weighed tentative signs of de-escalation in the conflict involving Iran against fresh threats from U.S. President Donald Trump, leaving markets cautious about treating the latest diplomatic developments as a durable turning point.
Sources told Reuters that Saudi Arabia had restarted operations at its East-West Pipeline and may already have resumed exports from the Red Sea port of Yanbu. The potential restoration of Saudi export capacity added to downward pressure on crude prices, with Brent futures falling 0.40% to $98.83 a barrel.

Trump said talks with Iran in New York had made progress, although he subsequently threatened to “annihilate” Iran if an agreement was not reached. The conflicting signals left investors assessing whether the latest diplomatic engagement could produce a sustained reduction in geopolitical risk or merely another temporary pause in hostilities.
“We’re probably nearing a point where it’s in both sides’ best interests to de-escalate the conflict and find a way to move forward,” said Brock Weimer, an investment strategy analyst at Edward Jones.
Iranian President Masoud Pezeshkian was scheduled to address the United Nations General Assembly later Wednesday, with markets watching for any indication that he could hold talks with Trump.
The possibility of a sustained recovery in oil flows through the Strait of Hormuz remains important for financial markets. The waterway is a critical channel for global energy supplies, meaning prolonged disruption could keep crude prices elevated, intensify inflationary pressures and complicate decisions by central banks on interest rates.
Investors, however, have seen optimism around a diplomatic breakthrough fade before.
“We’ve been through a series of starts and stops like this,” said Cole Smead, CEO and portfolio manager at Smead Capital Management.
The pan-European STOXX 600 rose 0.17% to 643.86 points. U.S. equity futures were also slightly higher, with contracts tracking the S&P 500 up 0.10% and Nasdaq-100 futures gaining 0.03%.
An MSCI gauge of global equities was broadly unchanged after four consecutive sessions of gains.
AI Optimism Broadens the Technology Rally
Technology shares provided another source of support for global equities as investors continued to respond to strong consumer interest in AI applications.
South Korea’s benchmark index gained 0.9%, with Samsung Electronics rising nearly 1%, while Taiwan’s benchmark advanced 0.8% toward record levels. Semiconductor and memory stocks have been among the strongest performers as investors look beyond AI infrastructure spending toward evidence of consumer adoption of AI-powered products.
The latest catalyst has been Meta’s Muse AI agent, which has topped U.S. app download charts over the past two weeks. Investors are now watching whether Alphabet’s Google Labs product, known as CC, can generate comparable consumer demand.
The importance of the response goes beyond individual applications. Sustained consumer adoption would provide another link between the enormous investment in AI infrastructure and eventual demand for AI services, potentially broadening the investment case for semiconductor, memory and data-center companies.
Memory stocks have increasingly taken leadership within the technology complex as semiconductor shares extended their gains.
“We expect a strong reopening in Japan tomorrow, with another move lower in crude, calm conditions in rates and Treasuries, and the Nasdaq cash and futures markets printing all-time highs,” said Chris Weston, head of research at broker Pepperstone.
“Memory stocks have taken the leadership baton, backed by another strong session for semis, which have recorded a sixth consecutive day of gains.”
Japan’s markets were closed for a holiday, although Nikkei futures traded at 66,775, around 1,760 points above the cash Nikkei’s Friday close.
The AI rally is also intersecting with corporate financing markets. SoftBank’s proposed debt offering of more than $10 billion has reportedly attracted over $20 billion in indications of interest, potentially making it one of the largest junk-bond transactions on record. Strong demand for the financing illustrates the willingness of investors to continue providing capital to companies positioned around the technology investment cycle, even as concerns over valuations and leverage remain.
Oil, Rates and The Dollar Remain Tightly Linked
The decline in crude prices also offered some relief to bond markets. Treasury futures edged higher, keeping the benchmark 10-year U.S. yield below the psychologically important 5% level.
That threshold has become closely watched because a sustained move above it could tighten financial conditions across equities, credit and currencies at a time when investors are already reassessing the path of interest rates.
Richmond Fed President Tom Barkin and Boston Fed President Susan Collins both supported last week’s interest-rate increase on Tuesday, citing concerns about inflation. Their comments reinforced the message that falling oil prices alone may not be enough to produce a rapid shift toward easier monetary policy if underlying inflation remains persistent.
The prospect of higher U.S. rates continued to support the dollar. The euro was trading around $1.1414, close to a two-month low, while the greenback also strengthened against sterling and the Canadian dollar.
The dollar was firmer against the yen at 157.76. Traders remained cautious about pushing the currency beyond 160 yen per dollar, a level that could heighten expectations of Japanese intervention to support the yen.
Currency markets are therefore caught between opposing forces. Higher U.S. rates support the dollar, while the risk of Japanese intervention limits how far the dollar-yen exchange rate can move. At the same time, lower oil prices could ease inflation in energy-importing economies and eventually reduce pressure on central banks to maintain restrictive monetary policy.
There is also a potential complication for Europe. Trump’s reported call to ban U.S. diesel exports could tighten fuel supplies in a region that relies heavily on American shipments. That means lower crude prices do not necessarily translate one-for-one into lower European inflation if refined-product markets remain constrained.
China added another layer of uncertainty to the global market backdrop. President Xi Jinping was due to arrive in Washington, with investors watching for signs that the existing U.S.-China trade truce could be extended and whether the two countries might find areas of cooperation on artificial intelligence.
For now, markets are balancing three competing forces: falling oil prices that could ease the inflation shock, renewed AI enthusiasm that is supporting technology and semiconductor shares, and geopolitical and monetary-policy risks that could quickly reverse the improvement in sentiment.
The immediate market response is seen as an indication that investors are willing to price in some reduction in the energy shock.
