LONDON, Feb 23 (Reuters) - World stocks rose from last week's three-month lows and government bonds fell on Monday as expectations grew that the U.S. government will increase its stake in Citigroup <C.N>, instead of fully nationalising it.
The low-yielding yen was the biggest loser in the currency market as global stocks rose and after the failure of domestic moneylender SFCG <8597.T> added concerns about the world's second largest economy which is mired in recession.
A source told Reuters that Citigroup is in talks that could result in the U.S. government increasing its stake in the bank. (For details please double click on [
])The Wall Street Journal said the government could own as much as 40 percent of the bank's common equity by converting preferred shares it holds into common stocks. The plan would not cost further taxpayer money. The government currently owns a stake of nearly 8 percent.
The news calmed fears over the bank's future and the prospect of a full nationalisation of the stricken lender, which not only depresses stocks but adds to the fiscal burden of the biggest world economy.
Shares in Britain's partly-nationalised Royal Bank of Scotland <RBS.L> jumped nearly 20 percent as it is expected to announce a restructuring to create a non-core division into which unwanted assets will be placed.
"Banks remain in focus, they are pivotal in terms of the market," said Jeremy Batstone-Carr, analyst at Charles Stanley. "Efforts to ring-fence toxic assets at RBS and the fact there appears to be no all-out nationalisation of Citi is steadying the ship." MSCI world equity index <.MIWD00000PUS> rose 0.7 percent after hitting its lowest since late November on Friday while the FTSEurofirst 300 index of leading European shares <
> gained 0.4 percent.U.S. stock futures were up around 1 percent <SPc1>, pointing to a firmer open on Wall Street later. Citi shares rose more than 12 percent in premarket trade.
"Global equities are in a bottoming process that began following the cathartic sell-off in early October," Tristan Hanson, manager of asset allocation and strategy at Jersey-based Ashburton, said in a note to clients.
"The basing pattern may continue for some months yet, but the combination of improving valuations and pervasive pessimism at a time of unprecedented policy stimulus makes the risk-reward trade-off of owning equities more attractive at current levels."
Emerging stocks <.MSCIEF> rose 2 percent and U.S. crude oil <CLc1> rose 1 percent to $40.44 a barrel. The March bund futures <FGBLc1> fell 45 ticks.
YEN UNDER PRESSURE
The yen hit a three-month low of 94.94 per dollar <JPY=>, bringing its losses this month to around 5 percent.
SFGC, a lender to smaller companies, failed with debts of $3.6 billion as tightening credit hits businesses throughout the economy, sending shares of other non-bank lenders sharply lower.
The Japanese currency has been under pressure and its perceived safe-haven status is weakening as the domestic economy deteriorates rapidly.
Uncertainty is intensifying over the country's political climate after the resignation of Shoichi Nakagawa as the finance minister this month led to a sharp decline in the approval rating of Prime Minister Taro Aso.
