The move against the US dollar was led by those currencies that one often associates with robust risk appetites, namely the Antipodean and Scandinavian currencies.  They all appreciated by more than 1%.  The dollar fell against most emerging market currencies, though the South African rand (-2.3%), the Chilean peso (-1.7%), and the Mexican peso (-0.3) were notable exceptions.  The dollar fell 0.4% against the Chinese yuan.  It was the fourth consecutive weekly decline.  Ahead of the weekend, the PBOC leaned against further yuan appreciation.
