Forget the war-spike narrative. TACO is back. Trump just paused the US military escort through the Strait of Hormuz, sending Brent crude tumbling from $115 to under $100 a barrel in two hours. The FTSE 100 jumped nearly 2%, Asian and European stocks rebounded, and the ‘Trump Always Chickens Out’ trade priced itself back into every macro book. The wartime $126 oil spike just hit reverse on a single Truth Social post.
How fast the market moved
The price action speaks for itself. Brent crude oil had been trading near $115 a barrel as Asian and European traders priced in another fortnight of escalation. Within two hours of Trump’s Truth Social post announcing the pause, the contract slipped under $100 a barrel — a move of roughly 13% on the headline price.
The FTSE 100 inched up by nearly 2% inside the first two hours of trading on the news. Asian and European indices rebounded in tandem. Currency desks logged sharp moves as the safe-haven bid unwound, and gilt yields softened as the imported-inflation outlook eased.
This is the textbook TACO trade in action: a maximalist threat from the White House drives oil and equity volatility wider, and the eventual climb-down hands traders one of the cleanest reverses in the macro calendar. Anyone who held short risk into the announcement and covered on the post — minted in two hours flat.
What Trump actually paused
Trump’s Truth Social post announced the pause of Project Freedom, the US military operation escorting commercial shipping through the Strait of Hormuz. Project Freedom had been the most visible American escalation of the past month — a direct response to Iranian threats against shipping in the chokepoint.
Two important footnotes. First, the blockade on Iranian ports remains in full force; only the escort operation has been paused. Second, US Secretary of State Marco Rubio confirmed that Operation Epic Fury — the broader offensive on Iran — has also ended as Washington pivots towards a negotiated agreement.
The trigger for the pause, per the post: the request of Pakistan and other countries, and what the White House calls “Great Progress” toward a “Complete and Final Agreement” with Iranian representatives. The French container line CMA CGM said one of its vessels was attacked in the Strait of Hormuz on Tuesday — a reminder that the chokepoint is still live, peace headlines or not.
TACO is the trade now
The TACO trade — short for “Trump Always Chickens Out” — has now priced itself in across multiple Iran-related cycles this year. Each cycle follows the same shape: maximalist threat, market spike, follow-up walkback, mean reversion. Today’s pause fits the pattern with such precision that traders are already trying to time the next iteration.
Neil Wilson, Saxo UK investor strategist, said: “There are three things certain in life — death, taxes and a TACO.”
The reality for any trader running an Iran-exposed book is that the volatility itself is the trade. Brent has whipsawed from war-spike highs of $126 back through war-pause lows below $100 multiple times this cycle. For UK-listed energy names, the same volatility has flowed straight through to share prices — Shell (LON: SHEL), BP (LON: BP), and the wider FTSE 100 have all priced the macro signal cleanly.
The risk: TACO works until it doesn’t. One escalation that doesn’t reverse changes the trade overnight, and the asymmetric downside on long-oil-shorts at that point is enormous.
What this means for the FTSE 100, gilts, and Reeves
For UK markets, the immediate read is straight-line positive. A drop in oil cools the imported-inflation pressure that has been driving petrol prices and headline CPI through the past month. Gilt yields softened on the news, easing the borrowing cost pressure on the Treasury. Sterling firmed modestly against the dollar.
For Reeves, every TACO swing is a small fiscal mood ride. Lower oil and lower borrowing costs are the friendly direction — but the volatility itself complicates Budget arithmetic. Forecasting next year’s borrowing requirement against a Brent price that swings from $90 lows to $126 wartime highs and back inside a month is hard work, even before the wider Iran-war fiscal hit is layered on.
UK energy stocks like Shell and BP sit on the other side of the trade — every oil-down move clips their FTSE earnings outlook, even as the index itself rises on rate-cut hopes.
For the FTSE 100, Wednesday’s 2% bounce is welcome but conditional. The same trade that lifted shares this morning could reverse on the next Truth Social post. Investors looking at the index right now are not pricing peace — they are pricing the option of peace.
The Bottom Line
TACO trades return until they don’t — and the next maximalist Trump threat is one Truth Social post away.
Don’t pretend this is the end of the Iran story. TACO trades return until they don’t — and the next maximalist Trump threat is one Truth Social post away. If you’re running oil-exposed books or FTSE 100 names through this cycle, the volatility itself is the asset class now. Watch the next escalation closely. The peace dividend is provisional until the deal is signed.

FAQ
Why is this called the TACO trade?
TACO stands for “Trump Always Chickens Out” — coined by market analysts who noticed that Trump’s most maximalist threats are usually walked back days or hours later. The pattern lets traders run the same playbook each cycle: short risk into the threat, cover the position when the climb-down arrives.
What is Project Freedom and why did it matter?
Project Freedom was the US military operation escorting commercial shipping through the Strait of Hormuz — the chokepoint pushing Brent to wartime highs when it launched. Pausing it has reversed that move; the blockade on Iranian ports stays in full force.
Why did the FTSE 100 specifically rebound on the news?
A drop in oil eases the imported-inflation pressure driving UK headline CPI through the past month — softer gilt yields, lower borrowing costs, supportive for FTSE 100 valuations across cyclical, financial, and consumer-facing sectors. The index’s 2% bounce reflects exactly that mechanism.
