Gulf Oil Flows Are Back. Prices Haven't Caught Up

The tankers are moving again, and the price on my screen has barely noticed. If you only watched headlines, you would think the Gulf was still shut. If you watch the ships, it is not.

The ships say recovery, with one barrel in thirteen still missing

Kpler satellite tracking, reported via ANZ Research and carried by Morningstar on October 1, put Persian Gulf crude shipments at 12.5 million barrels per day in the week ended September 27. That is about 1 million barrels per day below the pre-conflict baseline, which implies a baseline near 13.5 million barrels per day. I want to be precise about what that means: roughly 93 percent of normal Gulf flow is back, and roughly 7 percent is not.

Markets forgive a shortfall they can measure. A 1.0 million barrel gap is large, but it is a known gap. What spooks traders is not knowing whether tomorrow is 12.5, 8, or zero. That uncertainty is fading, which is why I see no panic buying even with prices elevated.

Yanbu matters because it gives Saudi crude a second door

Reuters reported on October 1 that Saudi Arabia restarted its East-West Pipeline and resumed tanker loadings at the Red Sea port of Yanbu after a drone-strike shutdown. I have learned to care less about any single terminal reopening and more about redundancy. A Gulf-only export system has one chokepoint. A Gulf-plus-Yanbu system has two doors, and the second door does not transit the Strait of Hormuz.

That geography is the whole story for me. When Yanbu loads, Saudi barrels can reach the Red Sea, transit Suez or round toward Asia without passing Hormuz at all. It does not replace Gulf loadings, and I would not pretend a single pipeline erases Hormuz risk. It does cap the worst case, and caps are exactly what insurance, freight, and futures curves price.

Reuters also noted on October 1 that Iran received a US response on reviving the collapsed Gulf ceasefire. I read that as a signal, not a settlement. Regional equities told the same cautious story the same day, with the Qatar index down 0.4 percent and Saudi TASI down 0.3 percent, per Reuters. Nobody is pricing peace. They are pricing a slightly lower chance of the worst week.

Prices eased a little. They did not declare the crisis over

Front-month Brent settled at $97.29 per barrel and WTI at $89.54 on October 1, based on ICE data via Morningstar and Dow Jones Newswires. NordFX Market Pulse the same morning had Brent down about 1.4 percent to near $96.7 and WTI near $88.9 intraday. I use both prints because they remind me this is a moving market, not a single magic number.

Why have prices not caught down? Flows measure last week. Prices measure fear about next month: whether the missing 1.0 million barrels returns, whether Yanbu stays open, and whether the US response to Tehran becomes a ceasefire. At $97, Brent is barrels today plus insurance for tomorrow. I do not find that irrational.

The macro tape is giving oil bulls less help than last month

US core PCE rose 0.2 percent month on month in August and 3.0 percent year on year. Market odds of an October Fed hike sat near 38 percent, down from 45 percent, per Reuters and NordFX on October 1, while the US 10-year yield stood at 5.28 percent, per NordFX. Falling hike odds mildly support crude, but a 5.28 percent 10-year keeps conditions tight. I read the backdrop as neutral-to-slightly soft: no reason to chase $110, no reason to assume $80.

Flows first, headlines second. Another week at or above 12.5 million barrels per day with Yanbu loading, and I expect Brent's insurance premium to bleed out gradually. If flows stall, $97 will look cheap. I would rather be roughly right about the ships than precisely wrong about the speeches.

FAQ

How much Gulf oil flow is still missing? About 1.0 million barrels per day. Kpler via ANZ Research put shipments at 12.5 mb/d in the week ended September 27 versus an implied pre-conflict baseline near 13.5 mb/d (Morningstar, Oct 1, 2026).

Why is Yanbu important if most Saudi oil still loads in the Gulf? Because it is a second export door that bypasses the Strait of Hormuz. Reuters reported October 1 that Saudi Arabia restarted the East-West Pipeline and resumed loadings at Yanbu, which caps the worst-case disruption even if Gulf loadings continue.

What were Brent and WTI prices on October 1, 2026? Front-month Brent was $97.29/bbl and WTI was $89.54/bbl on ICE data via Morningstar/Dow Jones Newswires. NordFX showed slightly lower intraday prints near $96.7 and $88.9 the same morning.

Are traders pricing in a new Gulf ceasefire? Not fully. Reuters reported Iran received a US response on reviving the collapsed ceasefire, but Qatar fell 0.4 percent and Saudi TASI fell 0.3 percent the same day, suggesting caution rather than relief.

What should I watch next to know if prices will fall? Watch sustained Kpler flow prints at or above 12.5 mb/d, continued Yanbu loadings, and whether the ceasefire channel produces verifiable shipping or inspection steps. One good week rarely moves Brent alone; two or three usually do.
