Standard & Poor's today (Wednesday) cut its credit outlook for Spain to "negative" from "stable," fanning concerns that sovereign defaults will spread throughout the global economy.
The dimmer outlook for Spain "reflects the risk of a downgrade within the next two years," S&P said.
It also increased fears among investors that the world could see a wave of global credit defaults. After the default of state-owned Dubai World forced investors to think twice about the recent rally in global stocks, Fitch Ratings Inc. on Tuesday cut Greece's credit rating to BBB+ from A-minus.
