US President Trump Rejects Iran's Strait of Hormuz Reopening Proposal, Oil Prices Surge Amid Reports of Iranian Missile Fire

Iran's Mehr News Agency reports September oil sales hit a two-year high; PrimeXBT reports August crude loadings collapsed over 80%.

Here's exactly what each side is claiming.

The disagreement: Mehr News Agency and Iran's Plan and Budget Organisation claim Iran's oil sales exceeded $3 billion in September, a two-year high, despite the blockade. In contrast, PrimeXBT, citing vessel-tracking data, states Iranian crude and condensate loadings in August averaged 220,000-260,000 bpd, an over 80% collapse due to the US naval blockade, reaching six-year lows by mid-September.

The rejection of Iran's proposal to reopen the Strait of Hormuz, coupled with reports of Iranian missile attacks on tankers and increased US military presence, significantly elevates regional shipping and energy market risks. Oil prices have surged in response.
