Price action was muted given the scale of the headlines, with Brent and WTI both essentially flat on the session, suggesting the market has already priced in a prolonged standoff rather than an imminent breakthrough. The surprise crude build capped early gains, but the bigger signal is structural: OPEC and the IEA both revising demand lower points to refiners, particularly in Asia, physically unable to secure enough crude while the Strait of Hormuz remains constrained, rather than a genuine drop in underlying appetite. The IEA’s widening deficit forecast for the third quarter argues the supply side stays the dominant driver, and with inventory buffers draining, any further escalation in shipping attacks carries outsized upside risk to price.

Crude is treading water on the surface, but a widening supply deficit forecast and draining inventory buffers suggest the underlying risk skews higher.
Summary:
- WTI and Brent both settled little changed on the day, trading in a range of around $82 to $84 and around $88 to $90 respectively
- An Iranian source told Reuters there is no discussion of extending the ceasefire, since Tehran views the existing deal as never having had a start date
- The US and Houthi forces reported separate attacks on shipping in the Strait of Hormuz and the Bab el-Mandeb Strait
- Vessel transits through the Strait of Hormuz fell to a one-week low of around eight on Tuesday, against a pre-war norm of roughly 125 to 140 a day
- OPEC trimmed its 2026 world oil demand growth forecast to around 580,000 barrels per day, while the IEA cut its demand projection and now expects a contraction of about 1.6 million barrels per day for the year
- The IEA also raised its third-quarter deficit forecast to around 1.8 million barrels per day, more than double its prior estimate of roughly 800,000 barrels per day, and flagged rapidly depleting inventory buffers
- US commercial crude stocks posted their largest weekly build since early 2023, rising by around 17 million barrels even as the SPR drew down by roughly 6 million barrels, for a net build of about 11 million barrels
- Pakistan’s Foreign Ministry said it continues to facilitate US-Iran diplomatic channels and that the ceasefire deadline, five days out, could still be extended
Oil prices were little changed on Wednesday, with Brent settling near $89 a barrel and WTI near $83, as traders weighed a stalled US-Iran ceasefire track and fresh attacks on Gulf shipping against a surprise build in US crude inventories and downgraded demand forecasts from both OPEC and the IEA. The session captured a market caught between competing signals: geopolitical risk that would normally argue for higher prices, and a swelling supply picture that kept gains in check.
The diplomatic backdrop deteriorated rather than improved. A senior Iranian source told Reuters there is currently no discussion between Tehran and Washington about extending their ceasefire, on the basis that the existing arrangement never had a defined start date and therefore nothing formally to extend. That contrasts with Pakistan’s Foreign Ministry, which said earlier in the session it continues to facilitate direct and indirect channels between the two sides and that the five-day ceasefire deadline could still be pushed back. Away from the diplomatic track, both the US and Houthi forces reported separate attacks on shipping in the Strait of Hormuz and the Bab el-Mandeb Strait, two of the region’s critical oil and gas export corridors alongside the Suez Canal. Vessel data showed transits through Hormuz falling to a one-week low of around eight on Tuesday, compared with a pre-war daily average in the range of 125 to 140.
On the supply and demand side, the picture turned more bearish. OPEC trimmed its 2026 global demand growth forecast to around 580,000 barrels a day in its latest monthly report, while the IEA cut its own demand outlook and now projects global oil demand will contract by roughly 1.6 million barrels a day this year. Analysts noted the demand downgrades likely reflect refiners, particularly across Asia, being physically unable to secure sufficient crude while Hormuz remains constrained and running plants below capacity as a result, rather than a genuine collapse in underlying consumption. The open question, as one portfolio manager put it, is how much of that lost demand returns once the conflict ends and how much represents permanent destruction. Working against that bearish demand read, the IEA simultaneously widened its third-quarter deficit forecast to around 1.8 million barrels a day, more than double its previous estimate of roughly 800,000 barrels a day, and warned that inventory buffers are being drawn down quickly, raising the stakes attached to any further delay in reopening the strait.
The week’s inventory data added a further bearish wrinkle. US commercial crude stocks recorded their largest weekly build since early 2023, rising by around 17 million barrels, even as the Strategic Petroleum Reserve was drawn down by roughly 6 million barrels, netting an overall build of about 11 million barrels. Analysts attributed the build mainly to unusually weak crude exports over the week combined with a jump in imports, rather than to any material easing in the underlying supply disruption. Gasoline and distillate stocks drew down by somewhat less than expected, while production held broadly steady at around 13.8 million barrels a day. Taken together, the session leaves oil markets positioned for continued two-way volatility, with the deficit and inventory-buffer story keeping a floor under prices even as diplomatic deadlock and shipping attacks argue against any near-term resolution.
