The machinery of optimism engaged. Then Iran's military spoke, and it ground to a halt.
On a Tuesday morning in Singapore, markets briefly exhaled as President Trump suggested the Middle East conflict might soon be over — a rare moment of geopolitical optimism that sent Asian stocks climbing and oil prices tumbling. But the reprieve was short-lived: Iran's military answered with renewed threats of missile strikes and oil blockades, reminding investors that words from Washington and realities on the ground remain two very different things. The episode speaks to a recurring tension in modern markets — the human longing for resolution, and the stubborn persistence of unresolved conflict.
- Trump's declaration that the Middle East war could end quickly unleashed a wave of relief buying, with the MSCI Asia-Pacific index surging 2.8% and Brent crude plunging as much as 11% within hours.
- Seoul's Kospi leapt so sharply — up 6.6% at its peak — that the Korea Exchange triggered an automatic trading halt, a rare mechanical brake on euphoria.
- Iran's Revolutionary Guards immediately shattered the mood, vowing to maintain an oil export blockade and threatening intensified missile strikes, while Trump countered with promises of overwhelming retaliation if the Strait of Hormuz was disrupted.
- Bond markets stayed unsettled, with stagflation fears lingering and traders pushing back their expectations for a Federal Reserve rate cut all the way to July.
- Analysts at BlackRock and ING urged caution, warning that the short-term panic had eased but the underlying conflict — and its inflationary pressures — remained very much alive.
Tuesday morning in Singapore delivered a familiar market paradox: a sudden surge of optimism, followed almost immediately by its undoing. President Trump declared the Middle East war could be resolved quickly, and for a few hours, traders chose to believe him. The MSCI Asia-Pacific index rose 2.8%, Brent crude fell as much as 11% before settling at a 6.6% decline, and Tokyo's Nikkei jumped 2.7%. In Seoul, gains were so dramatic that the Korea Exchange triggered an automatic trading halt. Even China's CSI 300 edged higher, buoyed by strong export data.
Then Iran's military responded. The Revolutionary Guards announced the oil blockade would hold until U.S. and Israeli attacks stopped. Hardliners rallied behind the new Supreme Leader. Threats of intensified missile strikes followed. Trump fired back on Truth Social, warning of overwhelming retaliation if the Strait of Hormuz was disrupted. The competing signals — peace rhetoric from Washington, defiance from Tehran — left traders uncertain which way to lean.
The bond market captured the unresolved anxiety. The U.S. 10-year Treasury yield dipped slightly, but stagflation fears from Monday's oil spike had not fully faded. Expectations for the Fed's first rate cut were pushed back to July. BlackRock analysts noted that markets were pricing in weeks of disruption — not days, not months — and warned that a stagflationary shock, while not inevitable, remained a real possibility. ING analysts added that any bond rally would likely be a temporary reversal trade rather than a structural shift.
The dollar ended the day flat, gold held steady, and cryptocurrencies drifted within the same narrow range they had occupied for weeks. Tuesday's relief, in the end, was genuine but fragile — a brief clearing in a storm whose end no one could yet see.
Tuesday morning in Singapore brought a familiar pattern to global markets: a sudden shift in sentiment, followed almost immediately by its reversal. U.S. President Donald Trump had declared that the Middle East war could be resolved quickly, and for a few hours, traders acted as though they believed him. Asian stocks climbed. Oil prices fell sharply. The machinery of optimism engaged.
Then Iran's military spoke, and the machinery ground to a halt.
The numbers told the story of that whipsaw. The MSCI index tracking Asia-Pacific shares outside Japan rose 2.8%, a meaningful rebound from losses that had accumulated since fighting began. Brent crude futures initially plunged as much as 11 percent, dropping below $88 per barrel before settling into a 6.6 percent decline. In Tokyo, the Nikkei 225 jumped 2.7 percent. Seoul's Kospi surged as much as 6.6 percent before moderating—gains large enough that the Korea Exchange triggered an automatic trading halt to slow the momentum. Even China's CSI 300 index climbed 1.1 percent, buoyed partly by customs data showing the country's export growth had accelerated in the January-February period, keeping it on track to exceed its record $1.2 trillion trade surplus for the year.
But beneath this surface relief lay a deeper tension. Iran's Revolutionary Guards immediately announced that an oil export blockade would remain in place until U.S. and Israeli attacks ceased. Hardliners rallied behind the new Supreme Leader, Mojtaba Khamenei. The military warned of intensified missile strikes. Trump responded on Truth Social with a threat: if Iran disrupted oil flow through the Strait of Hormuz, the United States would strike back twenty times harder than before. The competing signals—peace talk from Washington, defiance from Tehran—created the kind of volatility that leaves traders uncertain which direction to position themselves.
Tony Sycamore, a market analyst at IG in Sydney, captured the tension in his assessment. Trump's shift in rhetoric, from demanding full surrender to declaring the mission complete, represented a welcome toning down, he said. But reconciling that language with the actual state of the conflict remained difficult. The short-term panic had eased, but the underlying problem persisted.
The bond markets reflected this unresolved anxiety. The U.S. 10-year Treasury yield fell 2.1 basis points to 4.111 percent as traders reassessed inflation risks. Monday's spike in oil prices had triggered fears of stagflation—the toxic combination of stagnant growth and rising prices—and those concerns had not fully dissipated. Traders pushed back their expectations for the Federal Reserve's first rate cut, now not anticipated until July. BlackRock Investment Institute analysts noted that market pricing suggested weeks of disruption rather than days or months, and warned that while a stagflationary shock remained possible, it was not inevitable. They remained cautious on long-term Treasury bonds and favored U.S. stocks instead.
The dollar index, which measures the greenback against six major peers, finished the day flat at 98.84 after retracing all of the previous week's gains on Monday. Gold rose 0.8 percent to $5,177.96, holding within its recent trading range. Bitcoin climbed 1.4 percent to $69,976.73, while ether gained 0.9 percent to $2,043.86—cryptocurrencies remaining directionless, tracking the same narrow band they had occupied since early February.
Analysts from ING offered a sobering note: bond yields remained at troubling levels. A reversal trade might push nominal yields lower for a time, they wrote, but investors should not expect a dramatic structural rally in bonds. The economy was weakened but not broken. Clear inflation impulses remained to be overcome. The relief of Tuesday morning, in other words, was real but fragile—a temporary reprieve in a conflict whose end remained uncertain.
Notable Quotes
While all of this has helped ease some of the short-term panic, it's hard to reconcile the idea of the conflict being resolved when underlying tensions remain unaddressed.— Tony Sycamore, market analyst at IG in Sydney
Market pricing suggests weeks of disruptions, not days or months, and there's a risk of stagflationary shock but it's not a given.— BlackRock Investment Institute analysts
The Hearth Conversation Another angle on the story
Why did oil prices fall so sharply if the conflict is still unresolved?
Because markets price in expectations, not reality. Trump's statement created a narrative of resolution, and traders acted on that narrative immediately. The actual military situation didn't change—Iran's defiance proved that—but the psychological shift was enough to move billions in trading.
So the market was essentially betting on Trump's optimism?
Exactly. And when Iran responded with threats, the market had to recalibrate. That's what created the whipsaw. Traders had already committed capital based on one story, then had to adjust when a different story emerged.
What does it mean that the Fed rate cut got pushed to July?
It means traders are now expecting inflation to remain sticky longer than they thought on Monday. Oil spikes create inflation fears. If those fears persist, central banks stay cautious about lowering rates. It's a chain reaction.
The analysts said a stagflationary shock is possible but not certain. What's the difference?
Possible means it could happen if things deteriorate further. Not certain means the current data doesn't guarantee it. But the risk is real enough that serious investors are positioning defensively—favoring stocks over bonds, staying cautious on duration.
Why does the Strait of Hormuz matter so much?
Because roughly a third of the world's seaborne oil passes through it. If Iran blocks it, global oil supply contracts dramatically. That's not a market signal—that's a physical constraint on the world economy.
So Tuesday's rally might be temporary?
Almost certainly. The underlying conflict is unresolved. Markets got a moment of hope and acted on it. But hope and reality are different things.
