The dollar index held near its highest level in over four months on Wednesday, pinning the yen close to its lowest its decades, though the increased threat of currency intervention by Tokyo capped further declines in the Japanese currency.
The euro EUR=EBS was steady at $1.0766 as was the pound GBP=D3 at $1.2571, leaving the dollar index =USD , which tracks the unit against six peers, flat on the day at 104.82, having crept above 105 on Tuesday.
Euro zone inflation data is due later in the day, but with data from the biggest economies already released and broadly in line with expectations of a continuing slowdown, it is unlikely to have a major impact on the common currency.
The Japanese yen JPY=EBS was last at 151.7 per dollar, little recovered from last week's slump to 34-year lows of 151.975, as the Bank of Japan's historic policy shift only served to underscore its outlier status.
While the BOJ raised rates for the first time in 17 years, its policymakers' commitment to go slow on further increases have hammered the yen especially given the still-wide Japan-U.S. yield gap.
Japanese officials have carried on with their efforts to talk up the currency for days, with the threat of an intervention presenting stiff resistance for the U.S. dollar.
"It certainly seems like the market is very fearful of the 152 (yen per dollar) level," said Jane Foley, head of FX strategy at Rabobank.
She said she was also watching to see whether geopolitical tensions would have an impact.
"There is a feeling from gold and oil that there is a safe haven bid. But the question is why isn't it this affecting the dollar more, because the dollar was off against just about everything yesterday, and could this impact the yen or Swiss franc too?"
The three currencies typically benefit from a flight to safety, but the Swiss franc too is under pressure, trading at its weakest in several months against both the dollar and euro. CHF=EBS EURCHF=EBS
Gold is trading at record highs partly on geopolitical tensions, and oil is at its highest since October.
"Just because of the attraction of yields, I would say the dollar will be the more attractive safe haven currency," Foley added.

Manufacturing is growing for the first time in 1-1/2 years and in March, there was a greater-than-expected rebound in new orders for U.S.-manufactured goods, while the labour market stayed resilient.

Fed officials have also signalled that they are in no rush to ease rates.
The Chinese yuan, which has been shaken by a resurgent U.S. dollar, last stood at 7.2357 per dollar in the onshore market CNY=CFXS , languishing near a 4-1/2-month low hit on Tuesday, despite stronger Chinese manufacturing data, and Wednesday's service sector release.
Its offshore counterpart CNH=D3 softened to 7.2576 per dollar.
"Market participants will still try to push CNH (the offshore yuan) lower because of the economic headwinds facing the Chinese economy. Fundamentals still suggest that a weaker CNH is likely in the near term," said Carol Kong, a currency strategist at Commonwealth Bank of Australia.
The Australian and New Zealand dollars, which are often used as liquid proxies for the yuan, have come under pressure
The Aussie AUD=D3 was down 0.13% at $0.6509, while the kiwi NZD=D3 edged down a whisker to $0.596.
