PARIS — Standard & Poor’s downgraded the credit ratings of France, Italy and seven other European countries on Friday, a move that may have more symbolic than fundamental financial impact but served as a reminder that Europe’s economic woes were far from over.

Another memory jog came Friday from Greece, the original source of Europe’s debt troubles. Talks hit a snag between the new Greek government and the banks and other private investors that Athens hopes will agree to take losses on their debt so that Greece can avoid a default.

Together, those developments underscore that even as Europe’s debt turmoil enters its third year, no clear solutions are yet in sight — despite recent signs that a new lending program by the European Central Bank might be easing financial market pressures.

S.& P. warned in December that it might downgrade many of the 17 nations that share the euro, largely because it said European politicians were moving too slowly to strengthen the monetary union and because the euro zone’s problems were propelling Europe toward its second recession in three years.
