US stock market jumps after Trump's TACO moment
Wall Street has joined the global relief rally after Donald Trump postponed attacks on Iran’s power plants, sending a surge of optimism though trading floors.
In New York, the Dow Jones industrial average has jumped by 2% or 928 points to 46,505 points.
Construction equipment firm Caterpillar (+4.4%), manufacturing conglomerate 3M (+3.7%) and DIY chain Home Depot (+3.65%) are leading the risers.
The broader S&P 500 share index has rallied too, it’s up 1.9%.
Investors are relieved that Donald Trump has extended by five days his deadline to “hit and obliterate” Iran’s power stations and energy infrastructure if Tehran does not allow shipping to move freely through the strait of Hormuz, claiming that the US and Iran have held “very good and productive conversations” on an end to the three-week-old war.
With the markets so volatile today, George Lagarias, chief economist at Forvis Mazars has warned investors to respond only to verified facts.
Lagarias says:
“The volatility of asset prices faithfully mirrors the volatility of events in the Middle East, including competing, and conflicting, statements from Washington and Tehran. Despite the initial jump in risk assets, it’s becoming evident that the situation remains uniquely fluid. De-escalation is as much on the table as re-escalation.
Investors should remain calm and respond only to verified facts and agreed upon deals. At the heart of the market volatility is free movement in and out of the Straits of Hormuz, a very important global trade chokepoint. Until investors get assurance of at least a medium-term resolution that would ensure the resumption of normal trade in the Persian Gulf, they would do well to remain reserved.”

Most European stock markets posted gains today.

AJ Bell: Uncertainties remain despite 'handbrake turn' in markets
Today saw the market perform “a handbrake turn with juddering speed after President Trump suggested the US and Iran were close to ‘total resolution’ on their weeks-long conflict,” says AJ Bell head of markets Dan Coatsworth.
He adds, though, that there are “significant uncertainties remain for investors to pick through”, saying:
The Iranian regime has refuted the idea of dialogue with the US and, even assuming a deal can be agreed, questions of how and when the Strait of Hormuz will be unblocked and how quickly shipments through this strategically important body of water can get back to pre-war levels will remain.
“There will be a lot of focus in the coming days on whether the Trump administration’s position holds, whether talks can de-escalate the situation and whether the market can build on its new-found momentum. Hints of some renewed tetchiness as European markets headed for the close were a reminder that much is still to be resolved.
“If nothing else, today’s trading highlighted that markets can turn on a sixpence and that’s why time in the market rather than attempting to time the market is the best approach for most long-term investors.”
Back on Wall Street, the Dow Jones industrial average has dipped back from its earlier highs, but is still up 1.44% or 655 points at 46,233 points.
FTSE 100 closes after a remarkable day
Back in London, the FTSE 100 share index has closed down 24 points at 9,894 points, a drop of 0.24% today.
But that doesn’t capture the scale of today’s action at all!
The morning started with heavy selling, which drove the ‘Footsie’ down by almost 250 points at one stage to its lowest level since early December, adding to last week’s losses.
But there was then a resounding rebound, which put the index up more than 100 points today – back over the 10,000-point mark – after Donald Trump extended by five days his deadline to “hit and obliterate” Iran’s power stations.
Stocks then slipped back, though, as investors digested denials from Iran that constructive talks had taken place, as Trump claimed.

Gambling firm Entain (+8.2%) ended the day as the top riser, after reports of legislation in the US which would block betting on sports events on prediction market platforms.
It was followed by copper producer Antofagasta (+7.3%), with airlines and housebuilders also in the top risers.
But hopes of de-escalation in the Middle East hit shares in defence company BAE System (-4.9%), and BP (-4.2%).
Eurozone consumer confidence slides as Iran war drive up energy costs
Eurozone consumer confidence has fallen to its lowest level since late 2023 this month, a European Commission survey shows.
In a sign of the economic damage caused by the Iran war, eurozone consumer confidence fell to -16.3 this month from a revised -12.3 in February.
Eurozone consumer confidence took a big hit in March. Unsurprisingly surging petrol and diesel prices are a much bigger and immediate concern than the abstract economic hit from US tariffs, that was softened by partial TACOs and tariff front-running. pic.twitter.com/cIzhbq2hPY
— Oliver Rakau (@OliverRakau) March 23, 2026Andrew Kenningham at Capital Economics said.
“The four-point drop in March is one of the largest falls on record other than at the start of the pandemic and the Ukraine conflict.”
“Based on our current working assumptions about oil and gas prices, we think household spending will decline and cause GDP to stagnate over the next two quarters.”
The financial markets are now only pricing in two hikes in UK interest rates this year – down from four hikes early this morning.
The European Central Bank is also expected to raise eurozone borrowing costs twice by December.
Recessions can often be preceded by oil price spikes that prompt central bankers to tighten monetary policy., even though higher energy costs are a tax on consumers.
Kit Juckes, chief FX strategist at French bank Société Générale, explains:
Orthodox macro-economic models argue in favour of tightening monetary policy, even though the man or woman in the street wonders why the pain of higher energy, travel and food prices should be compounded by making money more expensive, too.
Market participants know that this is what happens and are pricing in ECB and BOE hikes by June, with a second hike by September. The rates market doesn’t currently price in a Fed hike, so the longer the price of oil stays elevated, the greater the probability of higher rates in Europe, outright and relative to the US, while the European despite Europe’s economic outlook deteriorating modes

Trump has also told reporters in Washington that his Middle East envoy Steve Witkoff and close aide and son-in-law Jared Kushner talked to the Iranians on Sunday and that discussions would continue on Monday.
Speaking before departing Florida to travel to Memphis, Trump said:
“We have had very, very strong talks. We’ll see where they lead. We have points, major points of agreement, I would say, almost all points of agreement... we’ve had very strong talks, Mr. Witkoff and Mr. Kushner had them.
“All I’m saying is, we are in the throes of a real possibility of making a deal.”
Aberdeen: We need to see than words
Asset manager Aberdeen is cautiously putting its toe into the UK government debt market, after Donald Trump calmed markets (for the moment….) today.
Matthew Amis, investment director at Aberdeen, says Trump’s statement is the circuit breaker that markets needed, adding:
The selling has stopped for the time being after a very weak start to the week. European sovereign markets, as you would expect, are reacting positively to the Trump headlines, despite the Iranian pushback.
However, to materially unwind the moves of the last few weeks, we would need to see more than words and clear action: namely ships moving through the Straits of Hormuz. Markets still have aggressive hikes priced for the UK and Eurozone in 2026. Although we don’t agree with the level, for those to be removed we would need to see energy prices fall a lot further.
Although this is merely a 5 day postponement, we believe today’s headlines at least show that de-escalation is possible. UK gilts have been beaten up over the last few weeks, with yields surpassing 5% on Friday we are therefore very tentatively buying UK Gilts.”
Sky News: Take Trump's announcement with 'grain of salt', says Israeli source
An Israeli source has told Sky News to take Donald Trump’s announcement “cautiously, with a grain of salt”.
They added:
“It’s early Monday morning in the US, the start of the trading week.
“Markets opened higher, largely as expected following the weekend reports on the negotiations and the latest statement by Donald Trump.
“That said, I wouldn’t view this move as a final step. We saw a similar pattern last week.”
US stock market's 'fear index' drops
Wall Streets ‘fear index’ has dropped sharply today, another sign that investors are more optimistic.
The Chicago Board Options Exchange’s CBOE Volatility Index, commonly known as VIX, has dropped by 10% today to 24 points.
It had earlier traded over 30 points just before Donald Trump postponed attacks on Iranian energy infrastructure following “constructive” talks.
Shorter-dated US and UK government bonds are both rallying today, as fears of an inflationary spike from the Middle East conflict ease.
The yield (or interest rate) on two-year US Treasury bills are down 6 basis points (0.06 percentage points) today, at 3.84%.
There’s a bigger fall in UK two-year gilt yields – down 20 basis points at 4.363%. That’s a sharp move – following days in which UK bond yields rose by more than other advanced economies, due to concerns over Britain’s fiscal position in the face of an energy shock.
Donald Trump has been insisting that the US and Iran were in discussions about ending the war, telling reporters there were “major points of agreement” between the two.
The US president said the US is talking to a “top person” within the Iranian regime to try to end the war, but not the new supreme leader, Ayatollah Mojtaba Khamanei.
Speaking after Iranian media denied that talks were happening, Trump declared:
“I didn’t call, they called – and they wanted to make a deal.”
When asked by CNN’s chief White House correspondent Kaitlin Collins who the US is talking to in Iran, Trump was quoted as having said:
A top person. Don’t forget: We’ve wiped out the leadership phase one, phase two and largely phase three.
But we’re dealing with a man who I believe is the most respected and the leader, you know it’s a little tough, they’ve wiped out – we’ve wiped out everybody.
Asked whether the US was talking to Khamenei, Trump said: “No, not the supreme leader.”
Back in London, two round numbers are attracting attention in the City.
The FTSE 100 is bobbing around the 10,000-point mark, which it tumbled through last week.
And Brent crude oil is hovering just above $100 a barrel.
US crude oil down almost 10%
US oil prices have dropped to their lowest level in over a week, on hopes of de-escalation in the Middle East.
The cost of a barrel of West Texas Intermediate (WTI) has fallen by 9.7% today, to $88.72 per barrel, on relief that Donald Trump has delayed any attacks on Iran’s energy infrastructure for at least five days.

European rally picks up pace
There’s no end to the volatility in the markets today.
The UK’s FTSE 100 share index is now up 63 points, or 0.64% today, at 9,983 points, despite the share prices of oil companies and weapons makers falling (BAE Systems are down 2.8%).
Tom Stevenson, investment director at Fidelity International, sums up the drama:
“A dramatic U-turn by President Trump has once again triggered gyrations in global financial markets. After heavy falls across bonds, shares and precious metals early on Monday, markets quickly regained their composure after threats to attack Iran’s power networks were abruptly withdrawn via a Presidential post on Truth Social.
“With the White House’s change of direction happening after Asian markets closed but before the US opened, the shift in sentiment played out most clearly in European markets. Having been as much as 2.5% lower, the FTSE 100 bounced back into positive territory within minutes of the US suspending its escalation threat.
“As the week’s trading began, investors had been looking in vain for safe havens as global markets eyed President Trump’s deadline for Iran to re-open the Strait of Hormuz. With Iran threatening retaliation if a promised attack on its power networks materialises, investors were concerned that the conflict has entered a newly dangerous phase.
“Despite a shaky start to the week, the impact on global markets remains relatively contained, as investors rightly price in the ever-present possibility that the US President might change tack. Investors are reluctant to give up on a market which continues to be supported by strong earnings growth and where an early resolution of the conflict could lead to a rebound in prices.
“As well as sharp recoveries in stock markets, bond prices rallied hard on the news. Gilts, where yields had risen above 5%, rose as the yield on the 10-year government bond dipped to 4.9%. That reflected a rapid drop in the price of oil, with the Brent contract falling 10% to $101 a barrel.
Today’s drama in the markets shows that the Bank of England should “sit tight” rather than react rapidly to events in the Middle East, says Professor Costas Milas, of the University of Liverpool’s management school.
Prof Milas tells us:
Trump’s predictably unpredictable post is puzzling. Having repeatedly stated that there is nobody to negotiate with, now Trump reveals that negotiations have taken place. All this creates large swings in financial markets and notably so in market expectations of UK interest rates. At the start of the war, money markets predicted no interest rate changes.
Earlier today, financial markets “concluded” that the BoE will raise interest rates from 3.75% to 4.75% before the end of the year. Now financial markets are thinking about more moderate interest rate rises and will have to wait for Trump’s next social post in order to change their mind yet again.
The point is that the sudden and constant change in market expectations of interest rates, almost entirely driven by Trump’s geopolitical actions and social media posts, demonstrates that the Bank of England’s policymakers should sit tight rather than rushing into any action!
Donald Trump just triggered “one of the most extraordinary market turnarounds in recent history,” says David Morrison, senior market analyst at financial services provider Trade Nation.
Morrison says US stock index futures “turned on a sixpence and roared higher” after Trump posted his (disputed claim) of productive talks with Iran.
He explains:
At around 10:45 GMT the S&P 500 had been trading near the low of the day, below 6,440 [points], and at its worst level since early September. Just twenty minutes later it was within sight of 6,700, jumping close to 4%.
The surge came after President Trump declared that: ‘... the US and Iran, have had, over the last two days, very good and productive conversations regarding a complete and total resolution of our hostilities in the Middle East.’ Crude oil prices cratered, while gold and silver, which had both sold off dramatically overnight, roared back to life tacking on 9% and 14% respectively from their session lows.
Iranian media deny that negotiations have taken place... it takes two to TACO
Iran’s Fars news agency has quoted a source as saying there has been “no direct or indirect connection” between Iran and Donald Trump, in contradiction to the US president’s statement.
Citing an unnamed source, Fars said Trump had retreated after hearing that Iran would respond by attacking all power plants in the region.
This has punctured some of the optimism in the markets.
Oil is now trading at $106.75 a barrel, still down 4.8% today, having ended last week around $112 a barrel.
European stock markets have slipped back a little too, but have still clawed back all this morning’s early heavy losses.
Germany’s DAX, for example, is still up 1%.
Neil Wilson, Saxo UK Investor Strategist, says:
Stocks have staged a monster rally off the lows after President Trump signalled the US and Iran have had “very good and productive conversations” over “total resolution” of hostilities, and that the US would postpone all military strikes against Iranian power plans and energy infrastructure for five days.
He posted on Truth Social but I would treat this with caution and it seems to already be refuted by Iran...it takes two to TACO remember.
