The dollar headed for a second week of gains on Friday, with a slight rate hike in Japan unable to halt its rise and a surprise cut in Switzerland highlighting the gap in interest rate policy between the Federal Reserve and other central banks.
The week marked a shift in global monetary policy as the Swiss National Bank (SNB) and central banks in developing countries cut rates or indicated their intention to do so, with June the likely moment for the European Central Bank to move.
The dollar rose against all G-10 currencies except the yen, as the relatively strong U.S. economy and high interest rates draw investment flows. But the Swiss rate cut, the first by a major central bank in Europe, marked a definitive shift.
"We had a somewhat surprising cut from the SNB this week," said Shaun Osborne, chief FX strategist at Scotiabank in Toronto. "People have been extrapolating, certainly from a signaling point of view, what that might mean for other central banks in Europe."
The Fed left its overnight rate on hold between 5.25%-5.5% and stuck with projections for three cuts by year's end. But it also said it would not start moving until it had more confidence that inflation was sustainably falling toward its 2% target.
About 83 basis points of cuts are priced in for this year - much lower than the 160 or so at the start of the year.
The Swiss franc CHF=EBS , the best performing G10 currency of 2023, has lost about 1.5% in value against the dollar this week and about 6.6% so far this year.
The dollar index =USD , a measure of the U.S. currency against six major trading partners, rose 0.26% while the dollar weakened 0.26% against the Japanese yen at 151.22 per dollar.
The dollar is up about 1.4% this week versus the yen and neared levels that prompted Japanese intervention in 2022.
Euro/yen EURJPY= hit its highest since 2008 this week at 165.37 and the Aussie broke above 100 yen AUDJPY=R for the first time since 2014.
With the dollar in the ascendant, the euro EUR=EBS hit a three-week low. It was last trading down 0.3% at $1.0829.
The Bank of Japan announced an historic shift out of negative short-term rates and longer-run yield caps, but it was so well telegraphed that the yen JPY=EBS fell on the news and was last at 151.17 per dollar.
"The stand-out for me has probably been the reaction of the yen from the BOJ," City Index strategist Fiona Cincotta said. "Just on the fact that the market was expecting a bit more of the Bank of Japan, in setting off on a new cycle and has been quite disappointed."
Expectations for policy easing in China too have piled pressure on its currency, which dropped sharply in the onshore session, spooking equity investors and prompting state banks to step in.
It was last at 7.229 per dollar CNY=CFXS , while in offshore trading CNH=D3 the dollar headed for its largest one-day rise against the yuan in a year, up 0.7% to 7.2716.
Sterling GBP=D3 dropped 0.6% to one-month lows at $1.258, following Thursday's 1% fall after the Bank of England left interest rates unchanged, this time backed by the two hawkish committee members who had previously voted for a hike.
Bitcoin BTC= was set for its largest weekly drop since last August, with a roughly 6% fall, as crypto markets have taken a step back from a powerful rally this week - though it will trade through until Sunday.
It was last down 3.46% on the day at $63,192, having fallen by some 13% since a record high close to $74,000 last week.
