LONDON—The Japanese yen jumped on Friday after the government and the central bank in a rare joint statement expressed concern about its recent slide to hit two-decade lows, while the dollar edged higher ahead of key U.S. inflation data.
After a meeting with his Bank of Japan (BOJ) counterpart, the country's top currency diplomat Masato Kanda told reporters that Tokyo will take appropriate action as needed, a sign Japan may be edging closer to intervening in the market in a bid to arrest the yen's declines.
The yen has been battered by traders wagering that the BOJ will stick with its ultra-accommodative policy stance just as the Federal Reserve and other central banks accelerate their tightening to tame soaring inflation.
"Generally if you look back at BOJ behaviour, if they say they will take appropriate action that is seen as the top level of intervention they go through before physical intervention. So, they have gone as far as they can go for now," Adam Cole, chief currency strategist at RBC Capital Markets, said.
The latest comments "should be a lid on dollar/yen in the short term," Cole added, but "in the long term, there's little that they can do as it flies in the face of the policy stance."
The yen rallied to as strong as 133.37 yen per dollar, up 0.7 percent on the session, before settling at 133.79. On Thursday it plumbed as weak as 134.56, levels last seen in early 2002.
The yen also rallied versus the euro, with the single currency last down 0.8 percent at 141.65 yen.
Elsewhere on Friday the dollar inched higher as traders braced for U.S. inflation data that should guide the Federal Reserve's policy tightening path.
U.S. core consumer price growth is expected to cool a fraction. This could give the Fed some wiggle room to raise rates less aggressively later in the year as it tries to rein in inflation without tipping the economy into recession.
Markets expect the Fed next week to announce the second of its three consecutive 50-basis-point interest rate hikes.
The dollar index, which measures the greenback against six peers, rose 0.2 percent to 103.52 but was still up this week as growth concerns encouraged investors to seek safety in the U.S. currency.
"For the U.S. dollar to become even more overvalued it will likely require some combination of intensifying global growth concerns and/or another significant hawkish repricing of Fed rate hike expectations," MUFG analyst Lee Hardman said.
The euro weakened, which followed a fall on Thursday after the European Central Bank meeting. The ECB said it would end quantitative easing on July 1, then raise interest rates by 25 basis points on July 21. It flagged a bigger rate increase in September.
The euro was last down 0.3 percent at $1.0587 having touched $1.0611 early in the session, its lowest since May 23.
The Norwegian crown gained, helped by the Norwegian statistics office reporting that the country's economy was growing faster than expected this year and inflation accelerating. The crown traded up 0.4 percent at 10.149 per euro.
The risk-sensitive Australian dollar climbed 0.4 percent to $0.7125 but was still down on the week, hurt by declines in equity markets. Sterling dropped 0.4 percent to $1.2441.
