Trump has spent the past year attacking Beijing on trade and is now, according to US News' September 20 report, preparing the diplomatic choreography of a state visit for Xi Jinping. The White House frames this as thaw. The People's Bank of China's open-market desk frames it as nothing yet, because the desk has not eased a single liquidity tool since Premier Li Qiang's economic working group signaled in March that monetary accommodation was contingent on a tariff resolution the diplomatic track has not delivered. Or, more precisely, the desk has held its overnight reverse repo rate flat through six months of summit preparation, which is the PBOC's way of telling Beijing's own negotiators that the ledger, not the seating chart, decides when the easing starts.

Mei Chen's brief today tracks the Taiwan arms sale Washington is weighing delaying to keep the summit alive. That is the security ledger. The finance ledger runs on a separate clock: the PBOC will not move until Premier Li's group certifies a tariff outcome, and a red carpet in Washington on September 24 does not certify anything the People's Bank recognizes as a document. Xi can attend the dinner without instructing the central bank to change course, and that is exactly the arrangement Beijing has built, a summit that costs Washington a arms-sale delay and costs the PBOC nothing at all. The open-market desk's next scheduled window to signal otherwise is the November reserve requirement review, and until then the flat rate is the only vote that counts.
