* Lat hits highest since mid-March on IMF loan hopes
* Jitters over devaluation remain, Baltic CDS jump
* Latvian overnight lending rates hit new record high
* Emerging equities index falls 1 pct

LONDON, June 4 (Reuters) - The Latvian lat and other Eastern European currencies rose on Thursday on expectations an IMF/EU loan deal might stave off Latvian devaluation pressures, which have spooked investors and sent lending rates soaring.
The lat rose to its highest since mid-March against the euro as currency dealers speculated the International Monetary Fund might agree to release another tranche of a previously-agreed loan to Latvia.
Jitters remained, however, and Latvian credit default swaps and overnight lending rates jumped after a sovereign debt auction flopped on Wednesday.
"Latvia is the main driver for all the eastern European currencies right now, but we could see some regional easing of pressure if the government and the IMF reach an agreement on fiscal issues," Gaelle Blanchard, emerging markets strategist at Societe Generale in London, said.
An IMF statement is expected later on Thursday. The EU issued a statement earlier on Thursday urging Latvia to tighten public finances.
The lat rose as far as 0.7074 <EURLVL=>, moving away from the 0.7098 level at which the central bank intervenes to support it.
However, the Latvian interbank overnight lending rate rose to a new record high of 25 percent <LVLOND=>.
Latvia's five-year credit default swaps (CDS), used to insure debt against default, rose to 721.1 basis points mid-price from a close of 675, according to CDS monitor CMA DataVision. Latvian CDS have risen 120 bps from a week ago.
Lithuanian CDS jumped over 30 bps to 481.9 while Estonian CDS rose nearly 15 bps to 366.3.
Poland's zloty <EURPLN=> and Hungary's forint <EURHUF=> rose 0.32 percent but remained at the lower end of recent ranges.
"(Latvia) is a factor that continues to weigh on CEE, in particular the forint, the risk proxy for the region, and the zloty, given the strong trade links with the Baltics," said analysts at RBC in a client note.
"Ultimately, other fixed FX regimes in Lithuania, Estonia and Bulgaria may go the same way, prompting renewed selling of CEE assets."
Some Latvia watchers, including a former prime minister, have said a Latvian devaluation was inevitable since the government drew up a budget that foresaw a 9 percent budget deficit and an 18 percent shrinkage in GDP.
Both Latvia's central bank and Prime Minister Dombrovskis said that a devaluation would be harmful to the country and repeated support for the currency peg.
Analysts say any devaluation is likely to be in the order of 25-30 percent.
Emerging European stocks rose slightly in line with currencies, stabilising from sharp falls the previous day, although the global benchmark MSCI emerging equities index <.MSCIEF> fell 0.9 percent.
Emerging sovereign debt spread movements slowed, narrowing 2 bps to 441 over U.S. Treasuries after widening 11 points the previous day (EMBI+) <11EMJ> <.JPEMBIPLUS>.
