Oil prices eased in Asian trade and were on track for sharp weekly declines after an interim U.S.-Iran agreement and the reopening of the Strait of Hormuz reduced fears of prolonged supply disruption. Brent and WTI fell in late U.S. hours, while lingering regional strikes and a firmer dollar kept traders cautious about a swift return to pre-crisis flow levels.

Key Points

  • Brent and WTI declined in Asian trade and were set for nearly 10% weekly falls, trading near lows not seen since early March.
  • An interim U.S.-Iran accord and the reopening of the Strait of Hormuz prompted ships carrying stranded oil to begin exiting the waterway, reducing the geopolitical risk premium.
  • Macro factors - notably a hawkish Federal Reserve stance and a firmer U.S. dollar - added downward pressure on oil prices.

Oil prices slipped in Asian trading on Friday and were poised for steep weekly declines as market participants digested the implications of an interim U.S.-Iran accord and the gradual restart of navigation through the Strait of Hormuz.

As of 20:22 ET (00:22 GMT), Brent Oil Futures expiring in August fell 1.1% to $79.01 per barrel, while West Texas Intermediate (WTI) crude futures slipped 0.7% to $76.05 per barrel. Both benchmarks were set to decline nearly 10% this week and were trading near their lowest levels since early March - when the U.S.-Iran conflict had just started.

Investor sentiment improved after Washington and Tehran signed an interim agreement intended to halt hostilities and restore commercial navigation through the Strait of Hormuz, the critical chokepoint that typically carries about one-fifth of global oil shipments. The deal raised expectations that millions of barrels of crude that had been stranded could gradually flow back to international markets over coming weeks and months.

The U.S. said it lifted its blockade on Iran on Thursday as the interim deal took effect. According to reports, ships carrying stranded oil began making their way out of the waterway on Thursday, signaling the initial return of cargoes that had been held back during the period of heightened tensions.

That prospect of renewed exports has removed a large portion of the geopolitical risk premium that had pushed oil prices above $120 per barrel at the height of the crisis. However, the outlook is not uniformly optimistic.

Early on Thursday, Israeli forces launched fresh airstrikes, an action that introduced doubt about the durability of the interim settlement. Industry analysts have also warned that a full restoration of Gulf oil flows will not be immediate, noting logistical, contractual and operational constraints that could slow how quickly stranded barrels re-enter markets.

At the same time, broader macroeconomic forces were exerting downward pressure on oil. A hawkish tone from the U.S. Federal Reserve - including signals that interest rates could stay elevated for longer - helped strengthen the U.S. dollar, which in turn added to commodity market headwinds.


Market participants will be watching both on-the-ground developments in the Gulf and macroeconomic signals for guidance on how quickly supply and demand will rebalance.

Risks

  • Renewed regional military activity - Israeli airstrikes early on Thursday raised doubts about the stability of the interim agreement, affecting energy and shipping sectors.
  • A full recovery in Gulf oil flows is likely to be gradual, according to industry analysts, which could prolong volatility in energy markets and affect refining and trading firms.
  • A stronger dollar and indications that U.S. interest rates may remain elevated could weigh on commodity demand and impact broader financial markets, including currencies and risk assets.
