* ECB rate hike will not prompt knee-jerk reaction in CEE
* History shows higher ECB premium not big risk to forex
* Poles to hike as already forecast before Trichet comments
* Hungarians seen on hold, Czechs seen hiking by mid-year

PRAGUE, March 15 (Reuters) - Low core inflation and the need to concentrate on fragile domestic recoveries are likely to insulate the European Union's eastern members from the euro zone's unexpected lurch towards tighter policy.
Speculation of knee-jerk hikes across the region rose earlier this month after European Central Bank President Jean Claude Trichet signaled the bank could raise its cost of borrowing in April.
But a look at rate developments over the last five years shows domestic inflation, and not ECB moves, has been the main policy driver in the developing countries east of the euro zone.
That does not mean Poland will hesitate to raise rates next month due to rising price growth or the Czechs before mid-year.
But those moves were forecast before Trichet spoke and economists do not expect them to be pushed forward, particularly because the commodity price inflation that has caused the ECB to shift focus has also not taken hold in the same way in a region where currency strength against the dollar has blunted its bite.
"We look at ECB policy, but I have to state that our decisions (...) are primarily, and almost solely, based on evaluating the state and tendency of this economy," Czech central bank board member Kamil Janacek told Reuters. <===============================================================

WARSAW TO RAISE
Poland's Monetary Policy Council is seen as the bank with the most room to tighten, having already raised rates in January by a quarter point.
Market watchers now expect it to hike its 3.75 percent base rate by the same amount next month and to 5.25 percent a year from now. But many analysts say that forecast might be too high.
Danske Bank's head of research, Lars Christensen, said one risk across the region would be if the ECB were to hike more than expected, which could hit currencies slightly and hurt the effect they have had by dampening inflation tied to high food and fuel costs.
But he added that for now, most of any expected tightening would come from domestic pressures, particularly in the region's biggest economy Poland.
And even though consumer price inflation unexpectedly hit a 21-month high of 3.8 percent in January, net inflation -- a measure closely watched by the central bank that excludes the impact of regulated and other volatile prices -- was just 1.6 percent in December.
"There are significant signals that the National Bank of Poland will hike, but it's all from domestic inflation. It's not coming from the ECB," Christensen said. "The pass through from the ECB to regional rates is not very high."
Hungary needs to maintain a high investment premium to keep the forint strong despite a running clash between the central bank and the right-wing government that has criticised the board for not supporting its pro-growth economic policy.
The bank has raised the cost of borrowing three times since November to 6 percent, citing government measures it says have eroded the country's risk profile and fueled inflation.
Since the last hike, the government has replaced two policymakers at the bank and will choose two more in a process that will stack the seven member board with candidates that most analysts expect to run relatively looser policy.
But so far the new members have suggested quick easing is not in the cards, which has caused many analysts to rethink their forecasts.
"I think they'll just stay on hold in the foreseeable future," said Nigel Rendell, a strategist at RBC.
RESILIENT CZECHS
A cursory glance would suggest that the currency most at risk of losing value would be the Czech crown.
Supported by interest rates of just 0.75 percent -- below the ECB's -- it would face a full half point discount if the Czech central bank refuses to chase ECB rates.
But the crown has firmed over 25 percent against the euro since the start of 2005, despite Czech rates being below the euro zone's for 53 of those 74 months. That included a period in 2007 when Czech rates lagged the ECB's by more than a point.
Now the Czech economy is also under pressure of a government belt tightening campaign aimed at cutting the budget deficit.
Fourth quarter growth was just 2.6 percent year-on-year, undercut by a 0.7 percent fall in household demand, while inflation was just 1.8 percent in February, below the central bank's target.
Janacek, one of a group on the council who narrowly failed to force a rate hike in January, said there were already domestic reasons for raising rates but any weakening of the crown due to the ECB would not be a concern.
"If the crown weakened after this (ECB) step, and it would probably weaken only slightly and in the short-term, exporters would welcocme it," he said.
The latest Reuters poll shows 12 of 18 analysts see a rate hike before mid-year, while a majority expects the two-week repo rate to rise to 1.25 percent a year from now. [
