US Federal Reserve chief Ben Bernanke says policymakers are mindful of the sliding US dollar.
Mr Bernanke says he's attentive to the decline in the currency and is working to "help ensure that the dollar is strong", the BBC reports.
But he also signalled that interest rates will be kept at a record low, a factor in the dollar's steep drop.
The US currency has dropped 13% against the pound and 6.4% versus the euro so far this year.
The comments are unusual, as the Fed rarely talks about the value of the US dollar.
