PBOC to inject 500bn yuan via 3-month outright reverse repos

This move signals the PBOC's preference for medium-term liquidity tools over shorter-duration operations, potentially flattening the yield curve at the front end. It affects interbank funding costs and banks' ability to lend, with implications for broader credit conditions. The open question is whether this is a one-off or the start of a shift in the central bank's liquidity management framework.
