Oil Crashes From US$119 to US$91 in 48 Hours: Should You Sell Woodside and Santos Now?

Oil just delivered one of its most dramatic reversals in years. Brent crude surged to an intraday high of US$119.50 on March 9 as US and Israeli strikes on Iran triggered fears of a prolonged Strait of Hormuz shutdown. Within 48 hours, prices had pulled back to around US$91 after President Trump signalled the Iran campaign would end soon. Woodside (ASX: WDS) had surged 33% in 2026 before retreating. Santos (ASX: STO) had climbed roughly 25%. Now both are sliding. For investors sitting on strong gains, the question is simple: stay or sell?

Why Oil Fell So Fast

The surge to US$119.50 was never built on a permanent supply shift. It was fear pricing. Traders rushed to price in the worst case: a full Strait of Hormuz blockade cutting off roughly 20% of global daily oil supply. The moment Trump suggested the US was considering taking over the Strait to restore shipping access, that fear premium evaporated almost instantly.

This is a pattern worth understanding. War-driven oil rallies unwind just as fast as they form because they are built on uncertainty, not actual lasting supply destruction. Two additional headwinds are now adding pressure. OPEC+ confirmed it will increase production by 206,000 barrels per day from April. The G7 is also discussing a coordinated release of strategic petroleum reserves. The US Energy Information Administration now forecasts Brent could fall below US$80 in the third quarter of 2026 if tensions ease. That is a sobering baseline for a sector that just had its best run in years.

Woodside, Santos and Karoon: Where Each Stock Stands Now

Woodside (ASX: WDS) is the safest place to be right now. The company posted record production in 2025, carries a dividend yield above 5%, and has the balance sheet strength to absorb an oil price pullback without breaking a sweat. Its LNG contracts also provide some pricing protection that pure oil producers do not have. We believe Woodside holders can stay put with confidence. This is the most resilient energy stock on the ASX in a falling oil environment.

Santos (ASX: STO) is a hold, but with more moving parts. The company shipped its first LNG cargo from the Barossa project in January 2026, and production is expected to rise around 30% by 2027 as Barossa and the Pikka project in Alaska ramp up. That production growth story is genuinely exciting. The concern is that recent share price gains are tightly linked to the oil price spike, and if crude drifts back towards the mid-US$60s, the earnings tailwind weakens quickly. Watch the Barossa ramp closely.

Karoon Energy (ASX: KAR) carries the most risk of the three. Its smaller size makes it far more sensitive to oil price swings in both directions. When oil rises, Karoon moves fast. When oil falls, it falls just as hard. With peace signals growing louder and structural oil forecasts pointing lower, this is where we would be most cautious. It is not a sell, but new investors should wait for oil to find a clear floor before adding exposure.

The Investor’s Takeaway

If Brent settles in the US$85 to US$95 range, Woodside and Santos can still generate solid cash flows and maintain dividends. The risk is a faster-than-expected resolution pushing oil back towards the low US$60s, exactly where forecasts sat before the Iran conflict began.

In our view, Woodside is the clear hold. Santos is a hold for patient investors who believe in the production growth story. Karoon is where caution is warranted. For anyone not yet in the sector, waiting for oil to find its footing before committing looks like the more disciplined approach right now.
