The dollar was on the front foot on Wednesday, pinning the yen near its lowest its decades though the heightened threat of currency intervention by Tokyo capped further declines in the Japanese currency. The offshore yuan was little changed ahead of a key services sector survey due for release later in the morning, as investors look to see if it reinforces China's recent run of upbeat data for the month of March. The yen was last at 151.48 per dollar, languishing near last month's slump to 34-year lows of 151.975 in the wake of the Bank of Japan's historic policy shift. While the BOJ raised rates for the first time in 17 years, 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 jawboning efforts for days now in a bid to defend the currency, with the overhanging threat of an intervention serving as stiff resistance for the greenback at the 152 yen level, which some market participants see as a line in the sand. The greenback's charge higher this week has come on the back of yet another run of resilient U.S. economic data, which showed manufacturing growing for the first time in 1-1/2 years in March, a greater-than-expected rebound in new orders for U.S.-manufactured goods, as well as a still-resilient labour market. Fed officials have also signalled that they are in no rush to ease rates. The Chinese yuan, which has been shaken by a resurgent greenback, last stood at 7.2569 per dollar in the offshore market. Its onshore counterpart had fallen to a 4-1/2-month low on Tuesday. The yuan's slide has come despite some brighter manufacturing data at home. A private survey showed earlier this week that China's manufacturing activity expanded at the fastest pace in 13 months in March, which followed equally upbeat official readings released over the weekend. The general view among analysts is that it is still too early to celebrate positive data outcomes as a protracted property sector crisis remains a major drag on the world's second-largest economy and investor confidence.
