The dollar hit a five-year high against the yen on Monday, as traders braced for the U.S. Federal Reserve to begin hiking rates, while reckoning the Bank of Japan remains dovish.
Commodities and commodity currencies eased amid hopes for progress in Russia-Ukraine peace talks. Cryptocurrencies rose after Tesla boss Elon Musk said on Twitter that he owns and won't sell ether, bitcoin and dogecoin.

"The Ukraine conflict is not expected to prevent the BoE and Fed from raising rates in the week ahead while the BOJ stands pat," said analysts at Japan's MUFG Bank.
"Unless there is a significant de-escalation in the Ukraine conflict, the dollar should remain stronger."
Futures are pricing in between six and seven U.S. rate hikes of 25 basis points each this year, and six in Britain as the war in Ukraine adds to global inflationary pressures.
