PBOC sets yuan mid-point at 6.4495 vs 6.4358 prior
Friday's trading close was 6.4553 so the weaker fix is no surprise.
The fixing is a bit stronger than the close but there's nothing here to prevent USD/CNH from rising to the top of the band again today.
The Chinese currency is in focus because of the introduction of two new yuan indexes on Friday that are designed to measure it against a broader basket rather than just against the US dollar.
