Spain is ready to request a euro zone bailout for its public finances as early as next weekend but Germany has signaled that it should hold off, European officials said on Monday.

Spain's debt levels are set to rise next year, piling pressure on the government to apply for aid as it pours funds in to cash-strapped regions, an ailing banking system and rising refinancing costs, its budget showed on Saturday.

Spain's borrowing costs still don't reflect the country's economic and fiscal adjustment, despite their recent easing, Economy Minister Luis de Guindos said on Saturday.

Spain will analyse the conditions and modalities of the European Central Bank's bond-buying program carefully and at length before taking a decision on an aid request, Spain's Deputy Primer Minister Soraya Saenz de Santamaria said on Friday.

With Rafa Nadal still out recovering from a knee complaint, David Ferrer will lead holdersSpain in their Davis Cup semi-final at home to the United States, captain Alex Corretja said on Tuesday.

Spain will consider seeking extra aid from Europe on top of a 100 billion rescue of its financial sector but does not see any need for new conditions, Prime Minister Mariano Rajoy said in an interview published in European newspapers on Sunday.

RadioShack-Nissan, a fusion of Lance Armstrong's former team and Leopard-Trek, are focused on the Tour of Spain and had no comment on overnight developments that threaten the American's Tour de France wins.

Stocks rose on Friday on news that the European Central Bank is considering setting yield band targets in a new bond buying program that could help contain borrowing costs for Greece and Spain.

Spain is negotiating with euro zone partners over conditions for aid to bring down its borrowing costs, though the country has not made a final decision to request a bailout, three sources with knowledge of the matter said on Thursday.

The European Central Bank must take forceful and unlimited steps to buy sovereign debt to help Spain reduce its refinancing costs and eliminate doubts over the euro zone's future, Spain's economy minister said in comments published on Saturday.

Spanish goods exports extended a strong run of growth in June, but a reliance on European buyers and the slow pace of structural reform mean policymakers' hopes that a rapidly improving trade balance may rescue the economy look misplaced.
