Onshore yuan closes at 6.6817 per dollar, up 51 pips

A 51-pip gain is a routine daily move, so the print itself carries little signal beyond confirming a firmer session. The detail worth noting is the small gap between the official close and the overnight close, which suggests the strengthening was not concentrated in late offshore-driven trading. With no driver cited in the item, whether this firmer tone extends into the next session, or fades as it has on similar modest moves, is the open question.
