Moody's Investors Service on Monday downgraded the long-term debt and deposit ratings for 28 Spanish banks and two issuer ratings, following on the heels of a cut to Spain's sovereign rating to just above junk status earlier this month.
The banks have several links to the sovereign, Moody's said in a statement, and so Spain's reduced creditworthiness "implies a weaker credit profile for Spanish banks."
The banks' exposure to commercial real estate was another factor in the cuts, Moody's said, because higher losses are likely, "which might increase the likelihood that these banks will require external support."
Among the downgrades was a cut to Banco Santander's
Still, Monday's move kept Santander one notch above the sovereign rating of Baa3, the Moody's release noted, because of the bank's geographic diversity and manageable exposure to Spanish sovereign debt.
Santander has considerable operations throughout Latin America, including Brazil, the region's largest economy. Its exposure in emerging markets, many of which are growing, helps offset stagnation in developed economies.
The rating agency also cut Banco Bilbao Vizcaya Argentaria SA
Spain formally requested European aid for its indebted banks earlier on Monday, but the lack of details rekindled investor doubts about the financial sector.
Analysts say the euro zone's fourth largest economy, which has become the focus of the debt crisis, will struggle to get out of recession unless the banking problems are solved.
