The US dollar slumped from its two-week high on Thursday as investors reduced their bets on an interest-rate increase. Although the U.S. House of Representatives had passed a bill to suspend the $31.4tn debt ceiling earlier in the week, the focus is now on how it will fare in the Democratic-led Senate. The dollar was mixed in Asia trade and hardly reacted to the vote. Markets currently believe that there is about a 26% chance that the US Federal Reserve will increase the rate 25 basis points at the meeting, down from the near 67% chance a day before.
