Brent Drops Through $80 as Hormuz Reopens, and Petro Rabigh Takes the Hit on TASI
Brent traded through $80 a barrel on June 17 as a Strait of Hormuz reopening deal took shape, its lowest since before the crisis began. The drop hit Petro Rabigh hardest, down 4.15 percent, while TASI slipped just 0.3 percent to 11,115. At $80, Saudi Arabia sits near its fiscal breakeven, but a working Hormuz lets export volumes recover even as the per-barrel price falls.

Brent traded through $80 a barrel on June 17, its lowest since before the Strait of Hormuz crisis began, as a deal to fully reopen the strait took shape. The clearest casualty on TASI was Petro Rabigh, down 4.15 percent, while the index slipped just 0.3 percent to 11,115. The split tells you the oil move hit where it should and left the rest of the market largely alone.
The drop is steep. Brent has fallen roughly 29 percent in about a month, from near $113 to the high $70s intraday, as the war premium drains out and traders price in barrels returning through Hormuz. Goldman Sachs cut its fourth-quarter Brent call to $80 and its 2027 average to $75 on the back of the deal.
Where it lands and where it does not
Petro Rabigh is the obvious pressure point. It is a chronic loss-maker carrying heavy debt, so its margins are acutely sensitive to crude and feedstock swings, and a sharp move lower in oil hits it harder than peers. Aramco eased about 1 percent, a measured move for the heavyweight. The rest of TASI was calm, with healthcare, telecom, and utilities largely untouched, and the day's biggest gainers, including Gulf Insurance and ELM, were stock-specific rather than oil-driven.
The bigger question sits at the budget level. At $80 Brent, Saudi Arabia is around the IMF's estimated fiscal breakeven and well below the level that funds Vision 2030 spending without widening the deficit. Aramco's performance dividend, the variable top-up above the base payout, comes under pressure when crude sits below the mid-$80s. Lower feedstock should in theory help petrochemicals, but global overcapacity means cheaper inputs mostly show up as cheaper products rather than fatter margins.
The offsetting force
The reopening is not all downside for the Kingdom. Saudi crude output was throttled to about 6.6 million barrels a day during the crisis, far below capacity, so a working Hormuz means volumes can recover even as the per-barrel price falls. The net effect on oil receipts depends on how fast Aramco can ramp shipments once the strait clears. The signal to watch is whether $80 holds on a closing basis and how quickly loadings recover.
