Oil dips below $80 as US-Iran deal nears, but Hormuz uncertainty lingers

Oil prices slipped again on Wednesday, June 17, holding just below $80 a barrel as investors weighed the prospect of an imminent deal to end the war between the United States and Iran against lingering uncertainty over how quickly the Strait of Hormuz might actually reopen. The move extended a multi-session slide that has pulled crude back toward levels last seen in early March, unwinding much of the war premium that had dominated energy markets for months.

The retreat gathered pace after Brent crude settled at $78.96 a barrel the previous day, falling 5% and dropping below $80 for the first time since March, while US West Texas Intermediate sank to around $76. The catalyst was a report that the United States would allow Iran to resume selling oil immediately once an agreement is signed, with sanctions relief taking effect straight away. The two sides have signaled they intend to sign a memorandum of understanding in Switzerland on Friday, an interim accord that would permit tankers to transit the strait and clear the way for Iranian and broader Gulf exports to return.

The prospect of restored supply has dramatically altered the calculus for traders. The effective closure of Hormuz since the war began had stranded a substantial share of regional crude, drawing down global inventories and, in the United States, pulling emergency reserves to their lowest level in more than four decades. With OPEC+ quotas higher and the UAE free to ramp up output after leaving the cartel, the market is now bracing for a wave of returning barrels that could quickly ease the shortage.

Yet the optimism remains tempered by significant uncertainty over implementation. Even with an agreement in hand, questions persist over shipping security in the strait, the operating conditions Iran might impose and whether the waterway would reopen fully or only partially. Both sides have yet to publish the details of the accord, and past episodes of apparent progress in the negotiations have repeatedly given way to renewed tension, leaving traders wary of declaring the crisis over.

Analysts have cautioned that the path back to normal could prove bumpy. Some bank strategists see the strait reopening by the end of June as their base case, forced by the mounting pressure on global oil stocks, but argue that the subsequent need to rebuild depleted inventories could keep Brent near $100 a barrel through the end of the year even after a deal. That view underscores how the physical tightness built up during the conflict may linger well after the diplomatic breakthrough.

The price action also unfolded against the backdrop of the Federal Reserve's interest rate decision due later in the day, which added a layer of caution across markets and gave traders another reason to hold back. A retreat in oil would, over time, help relieve the energy-driven inflation that has complicated the central bank's task, making the trajectory of crude a key variable for the monetary policy outlook.

For now, the oil market sits in an uneasy holding pattern, caught between the powerful bearish pull of an impending supply restoration and the residual risk that the deal could falter or that Hormuz might not reopen as smoothly as hoped. With the signing reportedly just days away, each headline out of the negotiations is likely to keep prices volatile, even as the broader trend points lower after one of the most turbulent stretches in the recent history of energy markets.
