Inflation, which accelerated to the fastest in two years in February on international food and fuel prices, may suffer further pressure from wage growth, Isarescu also said.
``The danger is that a second round of price increases, a so- called inflation spiral, will appear because of higher wages,'' Isarescu said. ``Economic growth is OK, but you have to not push it. I have to accept that politicians address economic growth because this seems like a simple success.''
The Banca Nationala a Romaniei increased its main interest rate last month by a half point to 9.5 percent, its fourth consecutive increase, after annual inflation rose to 8 percent in February. Net monthly wages rose an annual 31 percent in January.
Romania must cut the inflation rate to 3 percent by the end of 2010 or risk missing its target of adopting the euro in 2014, Isarescu said.
He also said the leu's current exchange rate is ``more sustainable'' than before. The leu has dropped 9 percent against the euro in the past year and was trading at 3.6566 to the euro as of 9:30 a.m. in Bucharest.
