We're still going to get Japanese rates at zero for some time yet. The Fed continues to underpin the view that more rate hikes are highly probable, and yield premiums favor the dollar in the short term.
M&A activity is likely to prove supportive for sterling and with recent economic data suggesting there is no risk of lower rates any time soon, I think the backdrop remains fairly constructive.
At the same time we had Greenspan reinforcing that the U.S. growth backdrop and rate outlook are positive for the dollar.
