Oil Prices Drop as Trump Announces Fresh Iran Talks, Yen Rally Weighs on Asian Markets

Oil prices dropped sharply on August 3, 2026, after President Trump announced fresh talks with Iran. Brent crude fell as much as 7.3% to a session low of $81.55 a barrel. WTI crude sank nearly 8% in early Asian trading. A coordinated US-Japan yen intervention added further volatility, pushing USD/JPY below 156. 

Asian equities traded mixed, with Japan’s Nikkei and South Korea’s Kospi both sliding despite the easing Middle East tensions.

Why Oil Prices Fell So Sharply Monday

Trump said he had cancelled a planned strike on Iran, calling it potentially “the biggest attack since World War II.” Talks with Iran were set to begin Monday afternoon.

• Brent crude later steadied near $83.88, still down more than 4% on the session.
• WTI crude fell in tandem, tracking Brent’s sharp intraday decline closely.
• Negotiations will reportedly cover Strait of Hormuz transit rights and Iran’s nuclear program.

Iran was also reported nearing a separate deal with Oman over an alternate Hormuz shipping route. That combination of diplomatic signals drove oil prices down across every major benchmark Monday.

OPEC+ Added to the Pressure on Oil Prices

Beyond the geopolitical news, OPEC+ made its own contribution to Monday’s oil price decline. Saudi Arabia, Russia, and five other members agreed to raise output further.

• The group approved a production increase of 188,000 barrels per day starting in September.
• This marks another incremental supply boost layered onto an already de-escalating Iran narrative.
• Combined, these two forces pushed oil prices toward multi-week lows during Asian trading hours.

Not every signal pointed toward lasting calm, though. Unconfirmed reports described an Iranian cruise missile incident near a US tanker, and Britain’s Navy flagged a separate Hormuz incident Monday.

The Yen’s Rally Is Reshaping Asian Trading

A rare, coordinated currency intervention added a second major storyline to Monday’s market moves. US Treasury Secretary Scott Bessent and Japan’s Ministry of Finance confirmed joint yen-buying action.

• This marked the first coordinated US-Japan currency intervention since 1998.
• USD/JPY plunged below the 156 level during Monday’s session.
• The yen had touched a near 40-year low of 164 against the dollar just last week.

Japan’s top currency official, Atsushi Mimura, said further Bank of Japan coordination remains possible if needed. Bessent echoed that stance, saying officials “will not hesitate to participate in further joint intervention.”

Chipmakers Dragged Kospi and Nikkei Lower

Despite falling oil prices, Asian equities still struggled to hold onto recent gains Monday. Chipmaker weakness proved the dominant force across regional markets.

Oil fell roughly $4–$5 per barrel after President Trump postponed planned strikes and said a rapid Iran agreement was being pursued.

Then Iran’s Foreign Ministry said no current talks with the United States were taking place.

• South Korea’s Kospi widened its losses to 4.86%, falling to 6,274.74 points.
• SK Hynix and Samsung Electronics led the Kospi’s decline after Friday’s record-breaking rally.
• Japan’s Nikkei 225 fell 1.12% to 63,643.61, unable to benefit from cheaper oil imports.

US equity futures showed a far calmer response, with S&P 500 futures up 0.5% and Nasdaq futures gaining 0.8% ahead of Monday’s open.

Broader Market Signals Worth Watching

Monday’s moves rippled beyond currencies and oil into bonds and safe-haven assets as well. Treasuries and gold both rose alongside the yen’s advance.

• European equity futures traded 0.7% higher, tracking the improved geopolitical mood.
• Berkshire Hathaway’s B shares closed Friday at $511.54, still 5.2% below their May 2 record.
• StoneX analyst Matt Simpson said the yen has likely “troughed for the year” after Monday’s move.

Markets now face two open questions: whether US-Iran talks yield a lasting deal, and whether Japan backs its currency defense with tighter policy.

Trump Halts Iran Strike
*Smarter in a minute*

President Trump has called off a planned military strike on Iran after appeals from Middle East allies including Saudi Arabia.

Fresh negotiations are set to begin as both sides step back from the brink.

Bottom Line

Monday’s selloff in oil prices reflects genuine diplomatic progress, not just short-term sentiment. But unconfirmed Hormuz incidents and a still-fragile Iran situation mean this de-escalation remains unconfirmed and reversible in the days ahead.
