Fitch Ratings warned on Wednesday that so-called US fiscal cliff is the top risk to the world economy, and expressed concern easing market pressure and elections could make the eurozone complacent. "Fitch has identified the US fiscal cliff as the single biggest, near-term threat to the world economy, given its potential to tip the US into an unnecessary and avoidable recession, with negative implications for global growth," it said in a report.

The agency warned if talks drag on about the $600 billion in tax increases and spending cuts due to come into force on January 1 then it may review and downgrade the United States' top AAA rating. Fitch also expressed concern that "the current easing of market pressure on sovereign bond yields - combined with the specifics of 2013's electoral calendar, including Italian and German general elections - could induce complacency and slow policy momentum to a crawl" in the eurozone.

For major advanced economies it said it expects only marginal improvement in growth rates, with growth picking up to 1.2 percent next year from 0.9 percent this year. Fitch said it expects major emerging economies will regain momentum, with Chinese growth rising to 8.0 percent next year, India to 7.0 percent (in the year to March 2014) and Brazil to 4.0 percent. Overall the ratings agency forecasts global growth to pick up to 2.4 percent next year form 2.0 percent this year.
