The dollar loomed over major peers on Thursday as Treasury yields peaked at multi-year highs, while the yen tumbled to a fresh 32-year low and kept markets on high alert for any signs of an intervention.
The benchmark U.S. 10-year Treasury yield rose to 4.148%, its highest level since mid-2008, while the two-year Treasury yields touched a 15-year high of 4.58%.
The Japanese yen hit a fresh trough of 149.96 per dollar, and last bought 149.95.
"Given that Treasury yields have moved decisively above 4%, were it not for the threat of intervention, then I think dollar/yen would already be trading north of 150."
