PBOC Governor China says the open market overnight reverse repo rate will correspondingly become the main policy rate; will pilot further facilitation of RMB purchases and sales by overseas financial institutions in the onshore foreign exchange market.

Elevating the overnight reverse repo rate to anchor status continues the PBoC's multi-year effort to simplify a framework that has long run several reference points in parallel, with the medium-term lending facility rate having served as the de facto policy signal and loan prime rate benchmark. The established sequence in transitions of this kind is that the legacy instrument is first de-emphasised as a signal, then its volumes shrink, and the short rate plus the standing facility corridor around it takes over the transmission work; money market rates are left to trade more tightly around the anchor while the curve beyond the front end prices off expectations of where the anchor goes. The practical tells are how the lending facility's role is wound down, whether the corridor is narrowed or adjusted, and how the loan prime rate is re-anchored, since that is the channel through which policy reaches bank lending. On the currency side, letting overseas institutions deal more freely in onshore FX is incremental internationalisation plumbing of a kind the PBoC has rolled out in pilot form before: it widens CNY liquidity provision and narrows the onshore-offshore basis rather than signalling anything about the desired level of the exchange rate. Worth watching is the follow-through in official communiqués and the central bank's daily fixing and open market operations, which remain the clearest read on intent. This is framework plumbing rather than a shift in the policy stance; the signal is about how policy is transmitted, not where rates are headed.
