Sergei Ignatyev said the ruble rate growth in 2006 was 7.4% against 10.5% in 2005.
The nominal effective rate grew 2.2% between December 2005 and December 2006, Ignatyev added.
It was earlier reported that February saw the national currency's real effective rate rise 1.1%, while in January-February the growth was 2.8%.
According to the economics ministry's final estimates, the ruble appreciated 1.8% against the dollar in real terms in January-February, 4% against the euro and 3.5% against the pound.
In its adjusted scenario for the country's social and economic development in 2008-2010, the ministry has ruled out the possibility of the ruble's appreciation in real terms in 2010, and expects a 0.6% depreciation.
The real effective rate of the ruble is expected to grow 1.3% in 2009.
Inflation was 3.4% in January-March, against 5% in the same period last year, Ignatyev said, adding that the economics ministry's estimates coincided with those of the Federal Statistic Service, the top statistics body.
The indicator of a general increase in the prices of goods and services was 7.4% for March 2006 through March 2007.
The Federal Statistics Service earlier reported that inflation slowed down in March to 0.6% from 0.8%, year-on-year, and stood at 1.1% in February and 1.7% in January.
"We do not expect a rapid increase in money supply to cause an inflation hike in 2007," Ignatyev said.
According to Russia's monetary policy guidelines for 2007, inflation is expected to slow down to 6.5-8%, which will lead to a 4-5% growth of the real effective rate of the ruble.
The official said Russia's money supply expanded 49% in 2006 and 39% in 2005.
Reports citing the Central Bank's data said in late March that Russia's money supply (M2) deposits gained 2.3% in February 2007 and stood at 8.902 trillion rubles ($341.1 billion).
Russia's M2 is defined by the Central Bank as total cash in circulation outside banks, plus ruble funds on accounts of resident non-financial organizations and individuals.
