Forex reserves were up by $7.02 billion to touch an all-time high of $681 billion as of August 23, as per data released by the Reserve Bank of India on Friday.

Earlier, reserves expanded by $4.54 billion to $674.66 billion for the week ending on August 16.

According to the Weekly Statistical Supplement released by the RBI, Foreign currency assets (FCAs) grew by $5.98 billion to $597.55 billion. Expressed in dollar terms, the FCAs include the effect of appreciation or depreciation of non-US units like the euro, pound and yen held in the foreign exchange reserves.

Gold reserves saw a surge of $893 million to $60.9 billion. Meanwhile, SDRs for the above mentioned week were up by $118 million to stand at $18.45 billion.

The RBI, from time to time, intervenes in the market through liquidity management, including through the selling of dollars, with a view to preventing a steep depreciation in the rupee.

The RBI closely monitors the foreign exchange markets and intervenes only to maintain orderly market conditions by containing excessive volatility in the exchange rate, without reference to any pre-determined target level or band.
