LONDON—The yen headed for a fourth weekly gain against the dollar on Friday, after its biggest rally in almost a year the day before, driven by a burst of optimism among traders that Japan’s ultra-low rates policy may soon end.
Activity overall across the market was muted ahead of the U.S. nonfarm payrolls report later on Friday.
The yen surged by as much as 1.2 percent earlier on, adding to Thursday’s 2 percent rally after Bank of Japan (BOJ) Governor Kazuo Ueda gave the clearest steer yet that the central bank is considering when to wrap up its negative rates policy.
The Japanese currency has vaulted to multi-month highs against a range of others in the last two days, although some of that strength dissipated over Friday’s European trading session.
The yen eased a touch, leaving the dollar up 0.2 percent at 144.46.
Thursday’s rally was the largest one-day jump for the yen since January. But without more impetus from the BOJ, it may not have much more scope for outsized gains, according to Fiona Cincotta, City Index market strategist.
“Without anything for the market to get their teeth into from the BOJ, the sell-off (in the dollar) has been done and, as far as the dollar is concerned, it’s almost as if it’s waiting for that next catalyst and that next catalyst is going to be today,” she said.
Yen on a TearThis week’s comments from the top of the BOJ has lit a fire under the Japanese currency.
The yen has fared best against higher yielding currencies, such as the pound.
Sterling fell to a two-month low against yen on Friday, but later recovered to rise 0.7 percent to 182, while the euro cut a nine-day stretch of losses, rising 0.2 percent to 155.87.
The BOJ meets later this month and the options markets shows traders are preparing for volatility around the event, even if the chances of an outright shift in policy are low, according to Ray Attrill, head of FX strategy at National Australia Bank.
“A lot of us have felt that we were going to have some sort of more meaningful policy change this year, and we’ve been disappointed. So I’m a bit reluctant to jump on the bandwagon and say that (a change) is going to happen on the 19th,” he said.
“But obviously, there’s no smoke without fire ... So I guess the market is understandably taking the view that the December meeting is live now.”
In the broader market, the dollar nudged up, although activity beyond the yen was subdued ahead of the jobs data.
The euro fell 0.1 percent to $1.0783, while the pound dropped 0.2 percent to $1.258, set for a 1 percent weekly fall.
Elsewhere, the Australian dollar rose 0.1 percent to $0.661, while the Chinese yuan was 0.1 percent weaker against the dollar in offshore trading at 7.171.
Data on Thursday showed China’s exports grew for the first time in six months in November, while imports shrank.
