LONDON (Reuters) - Russia's potential demotion to 'junk' credit status in January, a crunch review for Italy's debt at the end of March and a reappraisal of Britain after its election are key dates on Europe's 2015 credit rating calendar.
European Union rules introduced at the start of this year require Standard and Poor's, Moody's, Fitch and other ratings agencies that operate in Europe to publish the dates when they will review a country.
Ratings matter because many investors prefer to steer clear of debt judged to be non-investment grade or 'junk', and S&P has said it will decide in mid-January whether to push Russia into that category.
Russia is currently at BBB-, but with oil prices nearing $55 a barrel and the central bank having to work hard to prop up the rouble
S&P hasn't put an exact date on when it will 'resolve' its current downgrade review but if it doesn't cut it by the end of January it will have another opportunity on April 17.
Also under scrutiny will be Italy and France, founding members of the European Union which are struggling to revive their limping economies, and Greece, whose Jan. 25 election could underscore a popular rejection of its bailout terms.
On March 27, the smaller DBRS agency could deliver a downgrade to Italy that would cut 5 percent off the value of the bonds its banks use as collateral to get cheap funding from the European Central Bank.
"Italy remains a very, very problematic story and the risks are clearly to the downside," DBRS' head of sovereign ratings Fergus McCormick told Reuters this month. "Frankly no country can reduce its debt burden if it is not growing."
S&P has Italy, like Russia, on to the cusp of 'junk' at BBB- albeit with a stable rating. It will review Italy again on May 15, while Moody's and Fitch will do so on Feb. 13 and April 24.
France's Aa1 and AA ratings with Moody's and S&P are under 'negative outlooks' and scheduled for review on Jan. 23 and April 10 respectively.
S&P has also made France one of only two countries it will review three times rather than two. The other is Ukraine which is teetering on the brink of default.
For Britain, June 12 looks like a crucial date with reviews from both S&P and Fitch, just over a month after a general election that could put it on course for a national referendum on leaving the European Union. Only $&P among the major agencies still has Britain on AAA.
