(ANSAmed) — MADRID, AUGUST 29 — The announced pact between the PSOE and PP to introduce a clause into the Constitution that limits the public deficit has been viewed positively by rating agency Moody's, which will take the move into account in their analysis of Spain's sovereign debt rating. This was reported by sources from Moody's cited today by EFE, which warned: "establishing a fiscal law will not resolve the country's fiscal challenges by itself". According to Moody's, "even though it would have been preferable to include the maximum figure allowed for the deficit in the Constitution and to introduce clear mechanisms for corrections and sanctions" — and not by a special law as specified under the agreement- "the announcement is positive for Spain's sovereign debt".
