RBOB (Reformulated Blendstock for Oxygenate Blending) is the US benchmark gasoline commodity, traded as a futures contract on NYMEX (CME Group) and the primary settlement reference for US wholesale gasoline prices. The blendstock specification means RBOB is assessed before the mandatory ethanol splash; refiners sell RBOB to blenders who ADD ethanol at the terminal to meet EPA reformulated-fuel requirements in major urban markets.
In the European oil market context, RBOB functions as the A-leg of the transatlantic gasoline arbitrage, with EBOB (Eurobob oxy, the ARA barge benchmark) as the E-leg. When RBOB is priced high relative to EBOB plus TC2 freight cost and applicable duties, the arbitrage is open, incentivising European gasoline exports to the US Atlantic Coast via MR tankers and draining ARA barge stocks.
RBOB is also a mechanical component of NYMEX crack spreads, particularly the 3-2-1 crack (three barrels WTI cracked into two barrels RBOB plus one barrel heating oil), making it a direct proxy for US refining margins. CFTC Commitments of Traders data on RBOB positioning is watched as a leading indicator of speculative conviction in seasonal demand.
RBOB longs built into driving season
Managed-money net long on RBOB reached +71,095 contracts in the week to 23 June 2026, reported alongside crude's own positioning data on 27 June, as speculators built gasoline length into the US summer driving-season peak . By the following week, US petrol stocks had fallen 2.3 million barrels to 7% below the five-year average, the opposite of the same week's diesel build, with the RBOB long holding near that level .
For RBOB, that combination of a heavy speculative long riding a genuine stock draw is the setup a crack-compression trade needs: if crude falls before the position unwinds, the gasoline leg is exposed to amplify the drop rather than cushion it.
