The Nikkei's positive run today belies market sentiment in the region

Nikkei 17-05

Tokyo's main index mainly jumped as Sony announced a share buyback and new partnership with Microsoft, resulting in a 10% surge in its shares - helping to lift the mood among Japanese investors. If you look over to China, the Shanghai Composite index is down by 2% now and that's more indicative of the softer risk sentiment we're seeing so far.

US equity futures are also down by about 0.4% so that's continuing to put a drag on yen pairs, alongside weaker Treasury yields to start the day. USD/JPY holds at 109.64 currently, near session lows of 109.60 posted earlier.
