Before the conflict erupted in late February 2026, roughly 17 million barrels per day (mb/d) of oil transited the Strait of Hormuz, representing about 20% of global supply . The effective blockade of the strait from March through May cut flows dramatically. By June, Asia's imports of U.S. crude had surged to a record 63.56 million barrels in May, but this was still insufficient to compensate for the loss of Middle Eastern shipments . The EIA estimated production shut-ins peaked at roughly 6.7 mb/d .
By mid-July, S&P Global reported that Gulf oil flows were still 50% below pre-war levels . The escalation in July — including the U.S. naval blockade of Iran's entire coastline announced July 13 — pushed Brent to a one-month high . Asian refiners' plans to ramp up output in August were directly threatened .
The ceasefire was never durable: each truce was quickly broken, and Gulf oil flows never recovered to pre-war levels during July.
July saw extreme intra-month volatility:
Brent closed July up roughly 20% for the month, despite the late-month pullback . The EIA's July Short-Term Energy Outlook forecast Brent averaging $96/barrel for full-year 2026 and $76 in 2027 .
Analysts revised oil price forecasts sharply higher through 2026:
By late May, a Reuters poll of 33 economists and analysts projected Brent averaging $84.44/barrel for 2026 and WTI at $84.63 . The EIA's April outlook assumed Brent at $103/barrel in March 2026 .
Japan's big five trading houses were major beneficiaries of the supply disruption:
The path to normalization remained deeply uncertain as of late July 2026:
In short, July 2026 was a month of whiplash — a brief return to pre-war pricing, a dramatic spike to $100, and a late-month pullback — but with no lasting resolution. Asian import volumes recovered only fractionally from crisis lows, and the Strait of Hormuz ceasefire proved a temporary reprieve, not a turning point. Japan's trading houses posted record profit guidance from elevated energy prices, while the broader outlook hinged entirely on whether U.S.-Iran diplomacy could produce a durable reopening of the strait — a prospect that remained out of reach.
