PBoC is expected to set USD/CNY mid-point at 6.7170 (prev. 6.7828)

The daily fix is the PBoC's primary signalling instrument, and the established practice is to read the fix not on its level alone but against the consensus model estimate: a fix materially stronger than models imply has historically been the standard means of leaning against depreciation pressure, while a fix in line with models signals tolerance of the prevailing trend. A stronger fix than the previous session's, as flagged here, indicates the central bank is guiding the currency firmer or at least resisting the prior session's move, a pattern seen repeatedly in past episodes where authorities sought to slow one-way moves and deter speculative positioning. The transmission runs through the onshore trading band around the fix and through the CNH-CNY spread, which has tended to widen when offshore markets doubt the onshore signal. Worth noting is that model estimates of the fix incorporate the overnight dollar move and, where applicable, the countercyclical factor, so deviations from estimate carry the information. The follow-ons are the actual fix versus this expected print, the state of the CNH spread, and whether state bank dollar selling corroborates the signal in the onshore session.
