  • says the Chinese yuan remains basically stable, cross border capital flows basically stable amid higher expectations of monetary policy tightening at major economies
  • commercial banks purchased net $20.9 bln of forex in September vs net purchase of $13.6 bln in August

Those FX purchases would have, at the margin, slowed the appreciation of the yuan. Which may have been at least partially a goal of policy although I am having a guess.
