BUENOS AIRES, March 31 (Reuters) - The International Monetary Fund (IMF) approved Argentina's fourth review under its $44 billion loan program on Friday, unlocking the disbursement of $5.4 billion to the indebted country, the lender said in a short statement. The country's central bank foreign reserves jumped by $2.5 billion on Friday versus a day earlier, data from the bank showed. That reflected the new IMF funds minus $2.7 billion of repayments Argentina had to make to the lender on Friday. A central bank source told Reuters the funds had arrived and been reflected in reserve levels.
