# Dubai backwardation unwinds and Asian buyers walk away from Saudi crude
> The Dubai M1–M3 spread collapses from ~$37 to ~$8/bbl as the war premium fades, but Aramco's lagging formula left July differentials high enough to push China's Saudi intake toward ~600,000 bpd

## Summary

The [Dubai](/en/entity/dubai-crude) benchmark's wartime distortion is unwinding fast. The M1–M3 spread
, the near-vs-deferred gap that drives Gulf OSP differentials, 
collapsed from ~$37/bbl in March to ~$13 in April and ~$8 in May as the
[Hormuz](/en/n/hormuz-oil-supply-shock) tightness drained out. Because [Aramco's](/en/entity/saudi-arabia)
formula lags the spread, its Arab Light differential ballooned to ~$20/bbl in April and was
still ~$16 in May, pricing Saudi crude out of Asia precisely as cheaper grades returned.
[Chinese](/en/entity/china) refiners cut Saudi intake from ~1.6m bpd in February toward a projected
~600,000 bpd in June. The mechanism now points the other way: a flatter Dubai curve should
drag the July–August differential back toward $7–8, but the buyers have already substituted.

## By the numbers

- ~$37 → ~$8/bbl, Dubai M1–M3 spread, March to May 2026.
- ~$20 → ~$16/bbl, Aramco Arab Light differential, April to May (formula lag).
- ~1.6m → ~600,000 bpd, China's Saudi crude intake, February to projected June.
- ~$7–8/bbl, where the differential should reset as the curve flattens.

## Why it matters

Aramco's formula, built for slow-moving markets, amplified the war shock: it kept prices high
into a collapsing spread and handed market share to rival grades. Rebuilding Asian demand at
lower differentials takes time, compounding the revenue squeeze on a kingdom already running a
[record deficit](/en/n/saudi-q1-record-deficit) as [OPEC+ adds
volume](/en/n/opec-plus-august-acceleration).

## What to watch

- Aramco's August Arab Light OSP as the formula catches down to the flatter curve.
- Whether Chinese intake rebounds or stays with substituted grades.
- The Brent–Dubai (EFS) arbitrage steering buyers between Atlantic and Gulf barrels.
