Standard & Poor's is warning it may downgrade the European bailout fund's AAA long-term credit rating.
The move announced Tuesday follows S&P's notice on Monday that it may cut the credit rating of 15 eurozone countries, including Germany's, because the region's financial crisis is worsening without any imminent fix.
The agency says in a release that it is putting the AAA long-term credit rating for the European Financial Stability Facility on "CreditWatch with negative implications."
It says it could downgrade the rating by one or two notches.

BERLIN (AP) — Chancellor Angela Merkel on Tuesday downplayed Standard & Poor's warning that it might cut the credit rating of 15 eurozone countries, including Germany's, because the region's financial crisis is worsening without any imminent fix.
The timing of the warning was noteworthy. It came just hours after Merkel and French President Nicolas Sarkozy urged changes to the European Union treaty that would centralize decision-making on spending and borrowing for the 17 countries that use the euro. Tighter political and economic coordination among euro countries is seen as a precursor to further financial aid from the European Central Bank, the International Monetary Fund, or some combination.
The threat to cut Germany's prized AAA rating was particularly surprising. Its bonds are considered among the safest in the world. A downgrade threatens to complicate the eurozone's bailout mechanism, since the region's rescue fund relies on AAA-rated bonds of Germany and France to cheaply raise money.
Investors nevertheless seemed to take the S&P warning in stride on Tuesday. European stocks and bonds mostly held onto the gains they made Monday.
"What a rating agency does is the responsibility of the rating agency," Merkel told reporters in Berlin, refusing to elaborate further.
She said, however, that she expected a meeting of European leaders later this week in Brussels would help restore markets' confidence.
"We will meet on Thursday and Friday as Europeans and take those decisions that we consider to be correct, and through them stabilize the eurozone and also regain confidence," she said.
She and Sarkozy on Monday outlined sweeping plans to change the EU treaty in an effort to keep tighter checks on overspending nations. The proposal is set to form the basis of discussions at an EU summit in Brussels on Friday.
The financial markets of Italy and Spain rallied after Merkel and Sarkozy unveiled their proposals, suggesting investor are more confident Europe can survive the crisis.
"I have always said this is a long process and an arduous one and it will continue, but we charted the course yesterday with the French president and we will continue to stay the course," Merkel said.
S&P said there was a 50 percent chance that the countries' ratings it put on review would be downgraded.
Late Monday night the euro fell from $1.3460 to $1.3330, unwinding much of the gains made after Merkel and Sarkozy's proposals. By Tuesday, however, it was back up to $1.3420 — buoyed in part by a report showing a massive rebound in German industrial orders due to a double-digit increase in demand from eurozone countries.
Stock and bond markets largely overlooked S&P's threat, remaining stable on Tuesday. The bond yields for countries like Italy and Spain remained at the one-month lows they hit on Monday.
"Although the S&P warning has not scared the markets as it was pretty much stating the obvious, it did color the market sentiment," said Anita Paluch, a trader with Gekko Global Markets.
Paluch said the warning does raise pressure on policymakers, however, to use the upcoming summit to produce a solution that will "put out the fire in the eurozone."
French Foreign Minister Alain Juppe said it appeared to him that S&P had made its decision before Merkel and Sarkozy released details of the new plan, so hadn't been able to factor that into its considerations.
The leaders' proposal is "exactly the response to one of the major questions from the ratings agency, which talks about insufficient European economic governance," Juppe said on RTL radio.
Sarkozy and Merkel are proposing several broad changes for the EU treaty, including the introduction of a penalty for any government that allows its deficit to exceed 3 percent of gross domestic product. The penalty would be automatic — unless a majority of nations opposed it, a loophole that drew sharp criticism from analysts.
Some analysts also feel the proposal, which demands strict austerity measures, misses the mark and will only worsen much-needed growth in already feeble economies.
Investors are hoping that the summit of European leaders on Thursday and Friday will produce concrete measures to prevent a messy breakup of the euro. Markets have been jittery because of fears that the euro might disintegrate, causing a sharp recession in Europe that would spread through the world economy.
EU spokesman Amadeu Altafaj Tardio said that the bloc needed to make "important decisions this week" but not because of any worries about the S&P ratings.
"The job was already partially done in October" at the last summit, he said. "We now have to complete the job. It is not because we want to please the rating agencies or market forces, it is important because it is the best (way) to ensure the prosperity of our citizens."
The S&P warning left out only two of 17 countries that use the euro: Cyprus, whose bonds have near-junk status, and Greece, whose low ratings already suggest it is likely to default soon anyway.
