Heightened risk aversion was the key driver of foreign exchange moves in the Wednesday session. US equity bourses sold off heavily, while the dollar and yen benefited from safe haven flows. The greenback recovered against the euro toward the 1.4560-region while edging up to 1.95 versus the sterling. Meanwhile, the yen rallied to its highest level in 2 ½-years against the dollar to 104.98 and moved sharply versus the sterling and euro.
