The PBOC's currency desk logged the Hormuz closure as a supply shock on June 26, not as a headline event: crude moving through the strait accounts for roughly 20 percent of global seaborne oil, and China's term contracts with Saudi Aramco, ADNOC, and the National Iranian Oil Company run through the same chokepoint, meaning the desk's settlement book for Q3 deliveries is exposed to force-majeure clauses that lawyers at CNPC's trading subsidiary began reviewing within hours of the first US strike package. The Xi purge -- six generals stripped since mid-June, following the 2023-2024 PLA Rocket Force removals -- lands, in this context, as a compounding variable on the PBOC's risk calendar rather than as a separate political story, or, more precisely, as a signal that the decision-making chain for any PLA response to Hormuz disruption is being rebuilt at the same moment the disruption is live: CMC-level authority has contracted, operational commanders are newer to their seats, and the window in which Beijing can project a credible deterrence posture in the strait -- without triggering the credit-default swap spreads on Chinese sovereign paper that GS Asia rates began marking wider on Friday morning -- is narrowing as the US Navy's Fifth Fleet posture hardens around Bahrain and the UAE.

The institutional implication runs through the HKMA's Exchange Fund, which holds approximately USD 460 billion in foreign reserves and manages SAR dollar stability against a backdrop where an extended Hormuz closure reprices both the energy import bill for mainland industry and the risk premium on renminbi-denominated commodity contracts settled in Shanghai; the Exchange Fund's Investment Office has a hard Q3 review window, and a sustained US-Iran exchange lasting beyond mid-July forces a rebalancing decision on the energy and MENA sovereign-debt allocations that the Investment Office's September board presentation will need to account for publicly.
