Even a modest easing of inflation can provide meaningful relief
When markets reopened in Tokyo after a holiday pause, traders found a world quietly rearranging itself — Washington and Tehran edging toward an accord, oil prices retreating from their heights, and semiconductor earnings affirming that technology's momentum had not stalled. The Nikkei 225 surged past 61,900, catching up with rallies already absorbed by Western exchanges, as Japan's investors weighed the possibility that two persistent anxieties — geopolitical instability and inflation — might, at last, be loosening their grip. Yet even in moments of collective relief, the market reminded itself that fortune is rarely undivided: a strengthening yen cast its familiar shadow over the export economy that underpins so much of Japan's prosperity.
- The Nikkei 225 leapt 4% to close above 61,900, breaking through a symbolic threshold as Tokyo caught up with rallies that had swept through American and European markets during Japan's holiday.
- Optimism over a potential US-Iran memorandum of understanding — one that could reopen the Strait of Hormuz and lift port blockades — sent oil prices stabilizing after a dramatic 7% single-session drop.
- Semiconductor and tech names drove the surge: Kioxia hit its daily trading limit, Renesas and Ibiden ranked among top Nikkei performers, and AMD's strong earnings rippled across the Pacific.
- Lower energy costs offered tangible relief to Japanese exporters watching their margins, with strategists at Nomura noting that even modest inflation easing could carry outsized significance.
- A yen that strengthened nearly 2% against the dollar introduced a countervailing tension, reviving talk of currency intervention and reminding investors that export competitiveness remains a fragile variable.
Tokyo's markets returned from a holiday to find the mood transformed. Reports that Washington and Tehran were approaching a formal agreement had already lifted American and European exchanges, and Japanese traders moved quickly to close the gap — the Nikkei 225 surging 4% to close above 61,900, while the broader Topix climbed 2.1%. Oil prices, which had fallen sharply in the prior session, steadied.
The rally drew on more than diplomatic hope. Japan's technology sector had been building momentum for weeks, with semiconductor makers and chipmakers posting earnings that reinforced investor confidence. The Nikkei had already crossed the 60,000 threshold the previous month. Now, with energy costs retreating and inflation pressures easing, the case for Japanese equities grew stronger still. Nomura strategist Takashi Ito pointed to semiconductor and fiber-optic firms as likely leaders, noting that even a modest reduction in energy costs could meaningfully protect corporate margins.
The contours of the potential US-Iran deal added structural weight to the optimism — a reported memorandum that would gradually reopen the Strait of Hormuz and lift port blockades, changes capable of reshaping global energy flows. In Tokyo, the effects were visible in specific names: Kioxia hit its daily trading limit, Renesas and Ibiden ranked among the session's top performers, and AMD's strong American results carried their momentum westward across the Pacific.
Yet the session was not without its complications. The yen had strengthened nearly 2% against the dollar, reviving familiar questions about currency intervention. For an export-dependent economy, a rising yen is a double-edged development — cheaper imports at home, but more expensive goods abroad. Markets watched closely for any signal that policymakers might move to temper the currency's climb, a reminder that even in moments of broad optimism, Japan's economic balance remains delicate.
Tokyo's markets opened Thursday to a world that looked different from the day before. While Japanese traders had been away for a holiday, global sentiment had shifted—word was spreading that Washington and Tehran were inching toward a deal that might finally ease the tensions roiling the Middle East. The Nikkei 225, Japan's flagship stock index, surged as much as 4 percent to close above 61,902, catching up with the rally that had already swept through American and European exchanges. The broader Topix Index climbed 2.1 percent to 3,806.81. Oil prices, which had plummeted 7 percent in the previous session, steadied.
The gains were not simply a matter of geopolitical relief. Japanese equities had been building momentum for weeks on the strength of their technology sector—semiconductor makers, fiber-optic companies, and chipmakers had been posting earnings that justified investor confidence. The Nikkei had already broken through the psychological barrier of 60,000 the month before. Now, with oil prices falling and inflation pressures easing, the case for holding Japanese stocks looked even stronger. Takashi Ito, a senior strategist at Nomura Securities, framed it plainly: semiconductor and fiber-optic firms would likely lead the way forward, and the drop in energy costs meant real relief for companies watching their margins. Even a modest dent in inflation, he suggested, could matter significantly.
The mechanics of the potential US-Iran agreement added another layer to the optimism. Washington had reportedly presented a memorandum of understanding that would gradually reopen the Strait of Hormuz and lift blockades on ports—the kind of structural change that could reshape energy markets and global trade flows. US stocks had already hit new highs on the news. In Tokyo, the ripple effects were visible in specific names. Advanced Micro Devices, the American chipmaker, had rallied on strong results, and that momentum carried across the Pacific. Kioxia, Japan's memory chip giant, was positioned to rise by its daily trading limit. Renesas Electronics and Ibiden, both semiconductor-adjacent companies, ranked among Thursday's top performers on the Nikkei.
But not every force was pushing in the same direction. The yen had strengthened as much as 1.8 percent against the dollar on Wednesday, a move that rekindled talk of currency intervention. A stronger yen is a mixed blessing for Japan's export-dependent economy—it makes Japanese goods more expensive for foreign buyers, which can crimp sales even as it makes imports cheaper at home. The market was watching to see whether authorities would step in to manage the currency's rise, a signal of how seriously policymakers viewed the threat to export competitiveness.

Why did Japanese stocks jump so sharply when their markets had been closed?
They were playing catch-up. While Tokyo was on holiday, global markets had already moved on news that the US and Iran were nearing a deal. When Japanese traders came back, they were responding to a world that had shifted overnight.
But couldn't that have gone the other way—couldn't there have been bad news while they were away?
Of course. But in this case, the news was good for risk appetite. Lower oil prices, the prospect of reopened shipping lanes, reduced geopolitical tension—all of that favors equities, especially in a country that imports most of its energy.
The article mentions semiconductor stocks specifically. Why are they the ones leading?
Two reasons converging. Japanese chipmakers had already been posting strong earnings before this week. Now add falling oil prices, which ease inflation and make the outlook for corporate profits clearer. Investors were already confident in the sector; this just gave them more reason to buy.
What's the yen problem, exactly?
A stronger yen makes Japanese exports more expensive abroad. If you're a company selling cars or electronics globally, a 1.8 percent jump in the currency overnight is a headwind. It can erase profit margins or force you to cut prices. That's why there's always talk of intervention—the government trying to keep the currency from rising too fast.
So the market is celebrating, but there's a catch.
There's always a catch. The geopolitical optimism and the oil price relief are real gains. But if the yen keeps strengthening, it could start to undo some of that benefit for the companies that actually export things. It's a tension the market will have to work through.
