The Reserve Bank of India RBI on Friday said that India's foreign exchange reserves contracted by USD 897 million to USD 572.978 billion in the week ending August 5. The reserves had gone up by USD 2.315 billion to USD 573.875 billion in the last week ending July 29. The decline in foreign exchange reserves can be attributed to a dip in the Foreign Currency Assets FCA, a major component of the overall reserves, as per the Weekly Statistical Supplement released by RBI on Friday. The data showed that the FCA declined from USD 1.611 billion to USD 509.646 billion. The effect of appreciation or depreciation of non-US units like the euro, pound and yen in foreign exchange reserves is expressed in dollar terms. In the week ending August 5, gold reserves increased from USD 671 million to USD 40.313 billion. The country's reserve position with the IMF fell from USD 3 million to USD 4.987 billion in the reporting week, according to the data. With inputs from agencies.
