Xi-Trump summit May 12-14 to test durability of trade detente rally

China investors are positioning aggressively ahead of the Trump-Xi summit, betting that head-of-state diplomacy will preserve the trade détente that has underpinned the yuan's strength and equity inflows in May. China's central bank has noted that foreign central banks hit a two-year high in their use of PBOC swap lines in Q1, signaling rising international demand for the yuan under a risk-on backdrop. The summit presents a binary outcome for these flows: either continued pragmatic trade relations or escalation toward tariffs that would reverse the rally.

Trump has signaled he will discuss Taiwan arms sales directly with Xi, a move that risks undermining America's longstanding support for the island. Concurrently, US-Iran tensions remain elevated, with Trump rejecting multiple Iranian peace proposals. The timing matters because China's growth story has shifted toward robotics, green energy, and industrialization, according to KKR Head of Global Macro Henry McVey. This structural pivot is only viable in a stable trade and geopolitical environment.

Semiconductor exports loom as a key point of friction. US export controls on advanced chips have already impacted semiconductor design in China, but any new round of restrictions announced at the summit could trigger a sharp selloff in Chinese equities and tech names. Conversely, if Trump signals pragmatism on Taiwan or economic cooperation, cyclical Chinese exporters and financials would benefit sharply. Yuan appreciation has been orderly so far, but any deal announcement that locks in détente would likely push the currency higher, benefiting insurance and real estate sectors that need stable FX.

Skeptics note that Xi and Trump's relationship remains transactional rather than foundational. Earlier trade agreements have been ignored or modified unilaterally. If the summit produces only vague commitments with no specific tariff freezes or technology trade-offs, markets could rapidly reprice the détente as illusory. A breakdown would trigger sharp reversals in Chinese equities and emerging-market currencies.
