Oil prices have significantly dropped, with Brent crude falling below $75 per barrel for the first time since the Iran war began in late February. This decline is largely attributed to a notable increase in tanker traffic through the Strait of Hormuz, indicating growing confidence among shipowners and traders in the safety of this critical waterway. On Tuesday alone, 31 verified crossings, including crude, chemicals, container, bulk, and cargo vessels, were observed. Seven tankers, including two fully-laden non-Iranian supertankers, were broadcasting their locations as they transited the strait.

This uptick in traffic follows reported progress in peace talks between the United States and Iran, aiming to de-escalate the conflict and fully reopen the Strait of Hormuz. US Vice President JD Vance confirmed "good progress" had been made in initial negotiations for a lasting peace and the strait's complete reopening. The International Maritime Organization also announced receiving safety guarantees, allowing hundreds of ships to exit the Persian Gulf, further bolstering confidence. The United Arab Emirates, a key oil producer, is already exporting oil at nearly 85% of its pre-war levels.

The increased traffic and peace talk developments have led to a collapse in prices for physical crude. Brent crude, the global benchmark, was down by 4.03% to trade at $73.97 a barrel, while West Texas Intermediate (WTI) was trading 3.89% lower at $70.36 a barrel, briefly touching the $69 level. Iranian crude exports, which had plummeted to 329,000 barrels per day in May (an 85% drop from February's 2.2 million bpd), are now expected to surge following a reprieve from the US Treasury, further contributing to downward pressure on oil prices.

Despite the overall trend of falling prices due to increased supply, some markets show signs of tightness. The American Petroleum Institute (API) reported a 1 million barrel drop in crude inventories at the Cushing, Oklahoma, storage hub last week. If confirmed by official data, this would push stockpiles below the 20 million barrel minimum operating level. However, this has not offset the broader market sentiment driven by the re-opening of the Strait of Hormuz, with the US Senate also voting to end the war, highlighting a lack of domestic support for continued conflict.
