The dollar's rapid ascent against the euro has ground to a standstill this morning as investors exercise some caution ahead of upcoming US economic data. Analysts said US retail sales and producer price data may come in on the soft side, and are acting as a catalyst for investors to take some profits. A combination of dollar supporting factors pushed the euro down to 1.2036 usd yesterday, its lowest level since September 8. As recently as the end of April, it was trading as high as 1.30 usd. Michael Klawitter, currency strategist at WestLB, said investors may exercise some caution ahead of today's retail sales and tomorrow's TIC (US Treasury capital inflows) data. "The upward (dollar) move should come to a temporary halt," he said. He added that the rise in oil prices to their highest levels since the beginning of April may also limit the near-term upside in the dollar index. Analysts do not expect the euro rebound to last as all the fundamental factors that have boosted the dollar in recent days and weeks remain in place.
