New York: The US dollar held onto gains against major currencies early on Wednesday, as investors awaited the Federal Reserve decision on interest rates later in the day. The dollar firmed as much as 0.1% against the yen to touch a one-week top, last standing at 145.21 yen.

According to Qatar News Agency, in early Asia trade, the Swiss franc was flat at 0.816 a dollar, while the euro saw a slight increase of 0.1% at $1.149. A broader index tracking the greenback against six other currencies remained mostly unchanged after experiencing a 0.6% jump in the previous trading session.

The dollar has gained support as a safe bid, firming roughly 1% against the Japanese yen, Swiss franc, and euro since Thursday, which has helped offset declines from earlier in the year. The dollar had previously lost more than 8% earlier this year due to trade tensions.
