The euro fetched $1.3178 and 102.70 yen in Tokyo morning trade, compared with $1.3188 and 102.72 yen in New York late Monday. The dollar was flat against the Japanese currency, at 77.90 yen. The euro will likely test the downside following a plunge late Monday, said Osao Iizuka, head of foreign exchange trading at Sumitomo Trust and Banking. "The FX market has completely turned risk-off from Monday's European trade where stock markets tumbled," he said. European markets and the euro both fell Monday as Moody's Investors Services warned it would review EU nations' credit ratings. The agency said the debt talks had offered "few new measures" and that the crisis remains in a "critical and volatile stage." Fitch Ratings warned that "market tension remains high" and predicted a "significant" economic downturn in Europe, despite most EU countries agreeing to tighten budgetary coordination to tackle their fiscal woes. Iizuka said bearish sentiment on the euro would remain unless the European Central Bank abandons its reluctance to buy more eurozone sovereign debt. The euro may also lose ground if Germany's December ZEW Indicator of Economic Sentiment, due later Tuesday, registers a weak showing, said Sumino Kamei, senior analyst at Bank of Tokyo-Mitsubishi UFJ.
