The US dollar was weaker against the euro but slightly firmer against the yen in afternoon trading here, having found little little momentum to extend its surge in the Asian morning session, dealers said At 3.10 pm (0710 GMT) here, the dollar was at 112.14 yen, up from 112.08 yen in Tokyo nearly four hours earlier. The euro was at 1.2824 usd, up from 1.2791 usd in Tokyo Dealers said risk-averse sentiment and expectations of higher US interest rates had fueled a sharp rise in the dollar from its level in late New York trading overnight, and that this trend continued in Asia in the morning But the dollar failed to really make the most of its early gains, with Asian players clearly unwilling to follow through on the dollar's sporadic spikes in thin liquidity conditions, dealers said "Asian traders weren't too eager to push further," said one dealer. "Common knowledge is that decent sell orders are stacked up beyond 112.50 yen and they thicken near 112.90 yen for the 113.00 yen-barrier defense." Euro-dollar was equally volatile, oscillating between 1.2765 usd and 1.2826 usd Analysts said today's movements in the dollar were an indication of short-term flows, with the dollar being sought as a "safe-haven" instrument, rather than a reversal of the recent weak dollar sentiment
