The session in Asia-Pacific has been risk-on in tone, which has left the dollar lower against the euro and yen, and the G3 as a bloc down against various Asia and commodity-correlating currencies. The Indonesian rupiah, for instance, is registering its biggest three-day gain since 2008 on stock inflows, according to Bloomberg. The currency is up over 5% so far this week, and is a sign of improving sentiment to emerging markets in general.
