Oil settles 5% lower as investors await updates on US-Iran peace deal talks

Oil Prices Drop Amid Uncertainty Over US-Iran Negotiations

By Arathy Somasekhar

LONDON, May 27 (Reuters) - Oil prices fell 5% to their lowest level in over a month on Wednesday as investors awaited updates on a framework of a U.S.-Iran deal to end their conflict and reopen the Strait of Hormuz.

Market Performance and Price Movements

Brent crude futures settled down $5.29, or 5.31%, at $94.29 a barrel, while U.S. West Texas Intermediate crude lost $5.21, or 5.55%, to $88.68.

Both benchmarks touched their lowest in a month earlier in the session and settled at their lowest since April 17. The losses more than erased Brent's gains from Tuesday. 

Investor Sentiment and Negotiation Updates

 U.S. Secretary of State Marco Rubio said there has been some progress in negotiations with Iran toward a deal. However, President Donald Trump said the U.S. and Iran still have issues to resolve in peace talks, while Iran's Fars News has said unresolved issues remain. 

Washington also dismissed an Iranian state television report of a framework deal to restore shipping through the Strait of Hormuz within a month and to lift a U.S. naval blockade on Iranian ships. The U.S. will withdraw military forces from the vicinity of Iran and lift its naval blockade, Iranian state TV said, adding that the management of ship traffic through the Strait of Hormuz will be handled by Iran in cooperation with Oman.

Expert Opinions and Market Reactions

"A leader from the Iranian military stated that the possibility of returning to war is low, which has many traders believing a peace deal is getting closer ... It seems the extremely tight global supplies that had been factored into crude are beginning to lessen," said Dennis Kissler, senior vice president of trading at BOK Financial.

Strait of Hormuz: Shipping Activity and Geopolitical Impact

Traffic through the Strait of Hormuz also continued with an oil products tanker operated by Chinese shipping group COSCO in the process of crossing the chokepoint on Wednesday, after two crude tankers sailed in the past day, although oil traffic overall was still limited, shipping data showed.

"The increase in shipping activity is reinforcing expectations that the critical waterway could gradually reopen, potentially restoring disrupted global energy flows and reducing near-term supply risk premiums," said Mark Schaefer, a director at brokerage Liquidity Energy. 

Recent Developments and Regional Tensions

July Brent futures had risen 3.6% in the previous session after the U.S. carried out new strikes in Iran, hurting hopes that had risen over the weekend that Washington and Tehran would reach a peace deal. Israel ramped up bombing in Lebanon on Tuesday, further straining peace efforts.

After an April ceasefire in the three-month-long conflict, both sides indicated they had made progress in talks toward reopening the strait.

Supply Impact and Demand Signals

Iran's effective closure of the Strait of Hormuz has taken more than 14 million barrels per day of Middle East oil supply offline, according to the International Energy Agency. 

In a sign of demand weakening, India's two largest airlines sharply cut planned domestic flights for June and July, sources familiar with the matter said.

US Oil Inventories and Market Data

In the U.S.,crude oil inventories fell by 2.8 million barrels last week, the sixth straight week of declines, according to market sources citing American Petroleum Institute data. Gasoline inventories fell by 3.2 million barrels, while distillate inventories rose by 1.1 million barrels compared with a week earlier, the sources said.

Key Takeaways

  • Brent crude dropped about 1.4% to $98.16 and WTI fell 1.8% to $92.23 as traders seek clarity on U.S.–Iran talks and war escalation reversed prior gains.
  • Shipping data shows a cautious uptick in LNG and crude tanker transits through the Strait of Hormuz, signaling a partial easing of the blockade, but volumes remain far below pre-conflict levels.
  • Analysts caution that reopening the strait requires de‑mining and confidence among vessel operators; full normalization may take months even if a deal is reached.
