* Bahraini dinar, forwards fall as unrest deepens

LONDON, March 17 (Reuters) - Emerging currencies including the rand, won and real fell to around two-year lows against a surging yen on Thursday, but currencies and stocks in eastern Europe ticked slightly higher off recent multi-month lows.
Japan's unfolding nuclear crisis and deepening unrest in the Gulf were keeping a tight lid on risk appetite. That kept emerging stocks in the red -- they were down 0.6 percent to a five-week low <.MSCIEF>, with year-to-date losses of 5.5 percent.
Most Asian markets closed in the red, with China, Taiwan and India each losing more than 1 percent. India was also hit by an interest rate rise and a hawkish tone from the central bank.
Expectations that Japanese investors will repatriate overseas investments has boosted the yen and weighed on global markets, especially on those emerging markets where Japanese funds are heavily positioned.
The yen hit a record high to the dollar earlier on Thursday and surged against most other currencies.
The South African rand fell to its lowest against the yen <ZARJPY=R> since April 2009, Reuters data showed, while the Brazilian real was at a 20-month low <BRLJPY=R>. Another popular cross, the Korean won/yen <KRWJPY=R> also hit a two-year low.
"We are seeeing the yen strengthen a lot, a lot of stop losses are getting triggered and that is exacerbating yen strength, against the dollar and euro but also against emerging currencies," said UBS emerging markets strategist Manik Narain.
"These are basically carry trades suffering on the back of the yen move, it could potentially weigh more on these currencies."
South Africa and Brazil are seen as the emerging markets most at risk from any Japanese repatriation of cash as Japanese retail investors are estimated to hold 1-2 percent of the local bond market. The rand and real are also commonly used for issuance of uridashi, overseas bonds aimed at Japanese buyers.
JPMorgan recommended investors cut their exposure to emerging market currencies by 10 percent, forecasting global uncertainties would boost flows into safe-haven assets. It said Japanese investment in emerging debt amounted to around $20 billion of which Brazil accounted for a third.
"Commodity prices, equity markets and fixed-income markets have reflected the increased uncertainty and the possibility of a decline in the global growth trajectory. Emerging market foreign exchange has not," the bank told clients, cutting a range of emerging currencies in its model portfolio.
Japan's disaster has exacerbated concerns about global economic growth, especially as recent euro zone and U.S. data has been lacklustre, including U.S. housing and inflation data on Wednesday.
In Asia, investors were disappointed by a sharp fall in Singapore exports, which some analysts said could be followed by an even steeper slowdown due to the Japan supply chain shock.
"The market is getting concerned about the deterioraing global growth inflation mix and that is a bad backdrop for emerging currencies," UBS' Narain added.
Against a weaker dollar, the rand rose a quarter percent <ZAR=D3>, edging away from three-week lows hit earlier this week. The South African currency on Wednesday saw its biggest one-day fall in a year and has lost over 2.5 percent this week.
RUSSIAN EQUITIES GAIN
Continued tensions in Bahrain fuelled fears of oil supply disruptions, pushing up oil prices by $2 a barrel. That boosted Russian stocks, which jumped 1.2 percent <
>, leading regional gains. They are up 8 percent this year.Russian markets were led by state gas export monopoly Gazprom <GAZP.MM> which extended gains to hit a 2-1/2-year high, possibly as investors have dashed to invest in gas suppliers after the Japanese nuclear crisis. Russia's top non-state gas producer Novatek <NOTK.K> rose 1.2 percent.
Gazprom has risen more than 7 percent this week to post its biggest weekly gains since early December.
The ThomsonReuters eastern European index <.TRXFLDEEPU> rose 1 percent, with Warsaw rising 0.6 percent <
>.The rouble eased a touch versus the dollar as well as against its euro dollar basket but analysts expect the currency to outperform peers due to higher oil revenues as well as interest rate rises.
"Higher oil ... argues for a stronger rouble and we still favour long rouble versus short CE-3 (zloty, forint, crown) trades," BNP Paribas said in a note.
In the Gulf, the Bahraini dinar fell against its dollar peg to the lowest since 2009, though analysts said the move was prompted by very few trades. Investors also priced in a fall in the dinar via the one-year dollar/dinar forward <BHD1Y=> market.
Bahraini five-year credit default swaps eased 4 bps to 350 bps.
On the bond market, sovereign emerging bond yields tightened 7 bps over U.S. Treasuries to 278 bps but the index shows the yield premium has risen 15 bps since the end of last week. (Editing by Susan Fenton)
