A ninety-day pause is not a deal. It is a temporary ceasefire.
A ninety-day pause in the U.S.-China trade war brought measured relief to Asian markets on Wednesday, with most regional indexes rising modestly even as Japan's Nikkei declined — a reminder that a ceasefire is not a peace. Across the Pacific, unexpectedly cooling American inflation offered its own quiet reassurance, nudging the S&P 500 higher and easing fears of stagflation. Yet beneath the surface optimism, markets understood what they were really trading on: borrowed time, and the hope that something more durable might emerge before it runs out.
- A 90-day U.S.-China trade truce triggered cautious gains across most Asian markets, but the relief was tempered — South Korea and Hong Kong rose 1.1% while Japan's Nikkei slipped 0.8%, signaling that not everyone believed the ceasefire would hold.
- The truce's fragility is its own source of tension: economists and forecasters know that tariff rates remain unresolved, and the damage already done to supply chains and business confidence has no expiration date.
- U.S. inflation slowing to 2.3% in April gave American markets a more concrete foothold, pushing the S&P 500 up 0.7% and pulling the economy back from the edge of the stagflation scenario that had been quietly alarming investors.
- Nvidia surged 5.6% on news of an 18,000-chip deal tied to a Saudi Arabian data center, becoming the single largest driver of S&P 500 gains and underscoring how AI investment continues to cut through broader market anxiety.
- The Federal Reserve remains in a deliberate holding pattern, unwilling to move on interest rates until the trade and inflation picture clarifies — meaning markets will keep swinging on every headline that emerges from the negotiating table.
When Washington and Beijing agreed to pause their trade war for ninety days, Asian markets exhaled — but only slightly. South Korea's Kospi and Hong Kong's Hang Seng each climbed 1.1%, Shanghai edged up a modest 0.1%, and Australia's index dipped 0.1%. Japan's Nikkei, the region's largest market, actually fell 0.8%, closing at 37,874.59. The divergence was telling: some markets were willing to trust the truce, others were not.
The skepticism had a rational foundation. A ninety-day pause is a ceasefire, not a resolution. The deeper questions — where tariffs would ultimately land, and what economic harm the existing ones had already inflicted — remained entirely open. Fitch Ratings' chief economist Brian Coulton noted that without a lasting agreement, tariff uncertainty would continue to cloud forecasts for months ahead.
American markets found firmer ground in a separate piece of news: U.S. inflation had slowed unexpectedly to 2.3% in April, down from 2.4% in March. That single data point was enough to push the S&P 500 up 0.7% to 5,886.55 and send the Nasdaq surging 1.6% to 19,010.08. The number mattered because it moved the economy away from stagflation — the grim combination of stalled growth and rising prices that the Federal Reserve has no clean tool to address.
The S&P 500 had fallen nearly 20% below its record high just last month. Its recent recovery rested largely on the hope that the trade war would not escalate into recession. The inflation data gave that hope a small but meaningful boost, even as economists cautioned that businesses had been front-loading imports ahead of tariffs — a behavior that temporarily suppressed prices but could reverse once those goods arrived and tariff costs kicked in.
Nvidia was the day's standout performer, rising 5.6% after announcing a deal to ship 18,000 chips to power a Saudi Arabian data center backed by the kingdom's sovereign wealth fund. In bond markets, the ten-year Treasury yield ticked up to 4.48%, while oil prices slipped — U.S. crude fell to $63.23 a barrel. Currency moves were small but pointed: the dollar softened slightly against the yen, and the euro gained a touch against the dollar, reflecting investors quietly repositioning as they waited to see what the next ninety days would actually produce.
The news that Washington and Beijing had agreed to pause their trade war for ninety days rippled through Asian markets on Wednesday, lifting most regional indexes but not by much. The mood was one of relief, yes, but the kind of relief you feel when a headache subsides slightly—you're grateful, but you know it might return. South Korea's Kospi and Hong Kong's Hang Seng both climbed 1.1%, while Shanghai's composite index inched up 0.1%. Japan's Nikkei 225, the region's largest market, actually fell 0.8% to close at 37,874.59. Australia's index shed another 0.1%. The pattern was telling: some markets were buying into the truce, others were not convinced it would hold.
The caution made sense. A ninety-day pause is not a deal. It is a temporary ceasefire, and everyone in the market knew it. The real question—where tariffs would settle once those ninety days expired, and what damage the existing ones had already done—remained unanswered. Brian Coulton, chief economist at Fitch Ratings, put it plainly: without a lasting agreement, uncertainty over tariff rates and their economic impact would continue to shape how forecasters thought about the months ahead. That uncertainty was the invisible weight pressing down on otherwise positive sentiment.
Across the Pacific, American markets found more concrete reasons to move higher. A report released overnight showed that U.S. inflation had unexpectedly slowed to 2.3% in April, down from 2.4% in March. That single data point was enough to push the S&P 500 up 0.7% to 5,886.55. The Nasdaq composite, where technology stocks trade, surged 1.6% to 19,010.08. The Dow Jones Industrial Average fell 0.6% to 42,140.43, a rare moment when the broad market moved in a different direction than the blue-chip index. The inflation number mattered because it moved the economy away from a nightmare scenario economists call stagflation—an economy that stops growing while prices keep rising, a combination the Federal Reserve has no clean way to fix.
The S&P 500 had fallen nearly 20% below its record high just last month, a decline that had spooked investors and raised questions about whether the market's long run was over. But in recent weeks, as hopes grew that President Trump might ease his tariff threats before they triggered a recession, the index had recovered. It now sat within 4.2% of its all-time high from February and was positive for the year so far. Much of that recovery rested on the assumption that the trade war would not spiral into something worse. The inflation data gave that assumption a small boost.
Yet even economists who welcomed the slower inflation numbers acknowledged that tariffs posed a real risk to prices in the months ahead. Many businesses had rushed to import goods before tariffs could raise their costs, a behavior that had temporarily suppressed inflation. Once those imports arrived and tariffs took effect, prices could climb again. The Federal Reserve, watching all of this unfold, faced its own dilemma: it had signaled it would not move on interest rates for now, waiting instead to see how the trade situation and inflation evolved. That waiting game meant markets would likely remain volatile, swinging on each new headline about trade negotiations.
On Wall Street, artificial intelligence stocks were the day's strongest performers. Nvidia, the chipmaker that has become central to the AI boom, rose 5.6% and was the single biggest force pushing the S&P 500 higher. The company had announced a partnership to ship 18,000 chips to the Middle East to power a new data center project backed by Saudi Arabia's sovereign wealth fund. In the bond market, Treasury yields ticked higher as investors grew slightly more optimistic about the economy. The ten-year yield rose to 4.48% from 4.45%, while the two-year yield climbed to 4.01% from 3.98%. Oil prices moved in the opposite direction: U.S. crude fell 44 cents to $63.23 a barrel, and Brent crude declined 46 cents to $66.17.
The dollar weakened slightly against the yen, falling to 147.16 from 147.21, while the euro strengthened to $1.1192 from $1.1188. These small shifts in currency markets reflected the broader uncertainty: investors were repositioning themselves based on shifting expectations about growth, inflation, and interest rates, none of which were yet settled. The ninety-day trade pause had bought time, but time alone would not resolve the fundamental question of whether the U.S. and China could find a lasting way forward. Until they did, markets would remain in a state of cautious waiting, ready to move sharply in either direction depending on what came next.

In the absence of a lasting deal, uncertainty over where tariff rates will settle and the impact of those already implemented will remain key factors in our macroeconomic forecasts.— Brian Coulton, chief economist at Fitch Ratings
La Conversación del Hearth Otra perspectiva de la historia
Why did Japan's market fall when most of Asia was rising? That seems like it's telling us something.
Japan is the most exposed to trade disruption in the region. Its manufacturers depend heavily on global supply chains, and tariff uncertainty hits them harder than it hits, say, South Korea's tech sector in the short term. A pause is good news, but it doesn't erase the damage already done or guarantee what comes next.
The inflation number seems like the real story here. Why did that matter more than the trade truce itself?
Because inflation is what the Fed actually controls. A trade pause is political theater—it might last, it might not. But if inflation is genuinely slowing, that changes what the Fed can do with interest rates, which changes everything for investors. It's the difference between hope and data.
So the market is really just waiting for the Fed to move?
Not just waiting. The Fed is waiting too. They're watching to see if tariffs will push inflation back up. Markets are watching the Fed watch the tariffs. It's a chain of uncertainty, and everyone's frozen until someone moves.
What about those AI stocks? Why did Nvidia jump so much?
Because AI is the one sector that doesn't care about tariffs or trade wars. A company shipping chips to Saudi Arabia is making money regardless of what happens between Washington and Beijing. It's a safe harbor in an uncertain market.
Is this truce actually going to hold?
Nobody knows. The fact that markets are only cautiously optimistic tells you what traders really think. A ninety-day pause is not a deal. It's a timeout. When it ends, all the same tensions come back unless something fundamental has changed.
