* Putin stakes political prestige on Games
* Moody's say big macroeconomic boost unlikely
* Sochi's economic gain will depend on tourism

SOCHI, Russia, Feb 5 Hosting the Winter Olympics at great cost in Sochi is unlikely to give the Russian economy a big boost, ratings agency Moody's said on Wednesday, undermining one of President Vladimir Putin's main goals at the Games.
Putin has staked his personal and political prestige on hosting a successful Games, and promised the vast sums spent on Sochi would turn the Black Sea resort into an attractive tourism destination and give the Krasnodar region around it a lift.
But Moody's said in a report that uncertainty over the long-term legacy overshadowed the benefits of the Games, which are expected to cost more than $50 billion and have been marred by reports of widespread corruption and waste.
"While the central government can comfortably accommodate its share of the cost, the reputational benefits of hosting the Olympics have been undercut by the high cost of the event and other bad publicity," Moody's said.
Putin and his government have been banking on the Games giving Russia's stuttering $2.1 trillion economy a fillip but hopes that the Russian rouble would firm because of the so-called "Sochi effect" have proved unfounded.
The rouble is down more than 5 percent against the U.S. dollar since the start of the year and economic growth this year is expected to reach about 2 percent, much slower than in Putin's first eight-year spell as president until 2008.
Moody's said the Games would have a neutral impact on Russia's debt rating, that fiscal pressures on Sochi and the Krasnodar region would weigh on their credit profiles, and the outcome for Russian firms involved in the Games would be mixed.
State companies and private investors, including wealthy Putin allies who have sought political and financial benefits by investing in the construction of hotels and other infrastructure, may not cash in, Moody's made clear.
"The long-term gain depends on the hotel sector because the majority of the private investors invested in the hotel segment," Sergei Grushinin, an assistant vice president and analyst at Moody's, told Reuters by telephone.
"It depends on the Russian government's efforts to attract new tourists to Sochi which we estimate need to increase by 2.5 or three times after the Olympics to ensure that the majority of the hotels are full."
Such efforts would depend on Sochi being affordable and more attractive than European holiday destinations which are now preferred by many Russians and are well within their means.
State-owned banks that provided loans or invested in the equity of companies that helped transform Sochi from a Soviet-era resort into a modern sports hub would see a negative impact on their credit rating, the report said.
LITTLE COMFORT FOR PUTIN
Economists say the benefit of hosting major sports events tends to be fleeting. Britain got a short-term GDP boost from staging the London 2012 Games but the economy has gone into reverse again by the end of the year.
Almost the only winners from Sochi will be global corporate Olympic sponsors such as Procter & Gamble and General Electric, it said. For them, the Games would have a positive impact on their credit rating because of deals they concluded giving them exclusive worldwide marketing rights for their products.
The report provided little comfort for Putin. He is in danger of failing in his goal of using the Games to show Russia is a successful, modern state.
His record on democracy and human rights has been under scrutiny in the run-up to the Games, and the reports of corruption and cronyism - which he denies - have cast the political system he created in Russia in a bad light.
Because of these problems, hopes of an economic lift for Sochi and the Krasnodar region look increasingly important as he tries to portray the Olympics as a success for Russia.
Putin has repeatedly underlined these goals since arriving in Sochi this week to host political leaders and Olympic chiefs.
"It is largely thanks to the Olympic project that this gem on Russia's Black Sea will be able to fully realise its cultural and tourist potential, to attract guests not only with its unique natural environment but by also offering substantial infrastructure and hospitality options," he said on Tuesday.
Although there may be no big economic gains for Russia, Moody's and Fitch Ratings both said its economy was big enough not to suffer a big setback.
"Overall, the widely reported $50 billion costs relating to the Winter Olympics are less than 2.5 percent of our 2013 GDP estimate for Russia. With some costs privately funded, the impact on the sovereign's finances is minimal," Fitch said.
