The independence-minded region of Catalonia has asked the Spanish central government for an extra 9bn euros (£7.7bn) in bailout money, BBC News reported.
Catalonia's regional government said it needed the money to pay down debts and meet deficit reduction targets.
It adds to the 5bn euros the debt-stricken region initially requested from Spain in August last year.
The move comes just a month after Catalonia's new leaders pledged to hold a referendum on independence.
Catalonia is prosperous and accounts for around a fifth of Spain's GDP, but faces debt repayments totalling 13.6bn euros this year alone.
The regional government said it would spend 7.7bn euros to pay down debt and the rest on meeting deficit reduction targets set by the Spanish government.
