World stocks were mixed and the euro was flat on Friday as worries about downgrades of weaker euro zone countries curbed risk appetite, pushing aside an improved outlook on the U.S. economy.

Volume was below average across financial markets heading into the weekend. Trading was choppy as perceived risky assets gave up much of their initial gains.

Anxiety over potential ratings downgrades in European sovereign debt and their repercussion on the region's banks underpinned safety bids for U.S. and German government bonds.

Fitch Ratings on Friday placed Belgium, Cyprus, France, Ireland, Italy, Slovenia and Spain on watch for possible downgrade and warned that a comprehensive solution to this festering problem is technically and politically beyond reach.

It affirmed France's AAA-rating but could strip the second-biggest euro zone economy of its top-notch rating in two years.

Fitch's rating move and dire warning about Europe trumped optimism about the U.S. economy following recent upbeat data.

Government data released on Friday showed U.S. inflation pressure waning, fanning expectations the Federal Reserve could do more to boost economic growth. The latest consumer price report followed data on Thursday suggesting a possible pick-up in job growth, which has been meager during the current recovery.

Investor fears about the euro zone debt crisis persist as European leaders have not delivered more measures to contain the crisis after promising increased fiscal disciple at a summit in Brussels last week.

Long-term borrowing costs for Italy and Spain, whose heavy debt loads have worried investors and rating agencies, fell early in the trading day. That helped to steady the euro and briefly boosted European shares.

But they ratcheted back up to alarmingly high levels, with the yield on 10-year Italian government bonds creeping back above 7 percent, which analysts deem unsustainable for the euro zone's third-biggest economy to pay.

Italy faces a confidence vote in parliament, called to speed up approval of a 33 billion euro ($43 billion) austerity package aimed at restoring investor confidence.

Amid these political developments, worries linger about the euro zone debt crisis and have supported U.S. Treasuries and German Bunds. They pushed aside optimism about the U.S. economy and hopes the European Central Bank will ultimately step in to buy bonds of troubled euro zone peripheral countries.
