Although no US strikes were launched from Friday night into Saturday morning and the Gulf region remained quiet early Sunday, anticipation surrounding President Trump's next move is keeping energy traders and Gulf governments on edge. "Tonight from 9:36 PM to 9:37 PM the S&P 500 price on Hyperliquid spiked bigly, and I couldn't figure out why... ...then Trump posted his TACO @ 10:05 PM. A second source with knowledge of the call said MBS urged Trump to de-escalate and refrain from launching the strikes. Why the MBS-Trump conversation matters is that Saudi Arabia remains one of Washington's top Gulf region allies. Riyadh has heavily influenced Trump's Iran policy at previous inflection points and appears to have exerted similar influence in delaying or narrowing the next phase of US military action.
