Yuan Hits Strongest Since 2023 as Trump-Xi Summit Opens With Détente

Japan's Nikkei 225 rose for a third consecutive session to reach a record high, driven by technology sector momentum that drew additional fuel from the summit's de-escalation signal. The broader Topix slipped, indicating that the rally was concentrated in large-cap exporters and chip-related names that benefit directly from a stable U.S.-China trade relationship. South Korea's KOSPI extended its run to a second straight positive session, with Samsung Electronics touching record levels after the country's finance minister pledged action to avert a labour strike. The KOSPI had already closed at a record high the previous day, and the summit's early tone removed the geopolitical overhang that could have triggered profit-taking.

The equity moves are a textbook transmission of macro diplomacy into risk appetite. When the probability of a tariff shock or a technology-supply-chain disruption declines, the discount rate applied to future earnings in export-heavy indices falls. The Nikkei and KOSPI are among the most sensitive benchmarks to U.S.-China trade dynamics, and the record highs reflect a rapid repricing of that risk premium.

JGB Curve Steepens as Tokyo Weighs Fuel Subsidy Budget

A separate macro impulse came from Japan's fiscal policy. Kyodo News reported that the government is weighing a supplementary budget to cushion households from elevated fuel costs ahead of summer. The news pushed 30 and 40-year JGB yields higher on debt issuance concerns, steepening the yield curve even as the Bank of Japan maintains its yield curve control framework. Chief Cabinet Secretary Kihara pushed back on the reports, leaving the plan's status unclear. The market reaction, however, shows that any hint of additional supply is enough to move the long end, given the BoJ's already large footprint in the government bond market. A sustained rise in super-long yields would eventually feed into higher funding costs for Japanese banks and could strengthen the yen if the rate differential with the U.S. narrows, though that transmission is not yet active.

The next concrete marker is the summit's closing statement. A joint communiqué that codifies even a temporary truce on tariffs or technology restrictions would validate the early optimism and likely push the yuan and regional equities further. A statement that reverts to confrontational language would reintroduce the trade risk premium and reverse the yuan's appreciation. Until that text lands, the market is trading the tone, not the substance.
