BUENOS AIRES, May 28 (Reuters) - Argentina's economy ministry said on Wednesday the primary budget surplus jumped more than sevenfold on the year to 3.569 billion pesos ($446 million) in March, as an increase in revenue boosted by high inflation outpaced a rise in spending.
The primary budget balance, which reflects the government's finances before paying debts, rose from a surplus of 438.3 million pesos in March last year.
Argentina has been virtually shut out of global credit markets since a 2001/02 default and uses the central bank's international reserves to repay creditors.
