The dollar index gives up further ground to hit new three-year lows on Tuesday morning in Asia amid sustained worries of possible implication of Trump imposed tariff’s on the US economy. Moreover, US president Donald Trump criticizing Fed Powell over delayed rate cuts and exploring ways to oust the Fed chief are further damaging sentiment for the American currency. The dollar index that measures the greenback against a basket of currencies is quoting at 97.91, down 0.14% on the day. The decline in dollar is boosting yen and gold prices. Among basket currencies, EURUSD and GBPUSD are staying supported around a three year high at $1.15 and $1.34 respectively. The dollar has dropped nearly 6% this month and close to 10% so far this year.
