VILNIUS - Lithuania hopes joining the eurozone on Jan 1 will boost its security at a time of heightened anxiety over Russia, but many in the Baltic state fear the currency switch will also bring price hikes.
The stroke of midnight will signal the end of a year marked by Russian intervention in Ukraine - the biggest threat to the Baltic states since they broke free from the crumbling Soviet Union around a quarter of a century ago.
NATO has scrambled its fighter jets 150 times this year to escort Russian warplanes skirting the three Baltic states, three times more than last year, according to Lithuania's defence ministry.
"A single currency in Europe also means more security, and it's very important when we have such neighbours," said Vytautas Komka, a 50-something resident of the capital Vilnius.
Fifty-three per cent of the population of three million people backed ditching the litas currency for the euro, while 39 per cent were against, according to a November survey released by the central bank.
"Security concerns, I must admit, were among the reasons for the popular support for euro adoption," Finance Minister Rimantas Sadzius told AFP.
He hailed the move as "the third most important step in Lithuania's quest to integrate itself into the Western European community," after joining the EU and NATO in 2004.
But public support for the euro has wavered, dropping below 50 per cent at times in the face of widespread concern over the fallout.
"The euro will not increase pensions or wages, it will only increase prices," pensioner Danute Petkeviciene told AFP.
"But they have already decided," she said, referring to the central bank's countdown to when Lithuania becomes eurozone member 19.
Hopes and fears
Unlike neighbouring Poland, which has a free-floating currency, the Lithuanian litas has been pegged to the euro since 2002, making it dependent on the European Central Bank.
"We've actually already had the euro for more than 12 years but it was called the litas," Sadzius said, adding that prices will go up by no more than 0.2 to 0.3 per cent after the switch.
Lithuania had hoped to adopt the euro in 2007 but failed to meet the inflation criteria.
It suffered a deep recession in 2009 during the global financial crisis.
A painful austerity drive paved the way for the euro and made Lithuania one of the fastest-growing economies in the EU, with output expanding by around three per cent in recent years.
But social security cuts and other slashed public spending also encouraged record emigration to richer West European nations such as Britain.
Fellow Baltic states Estonia and Latvia joined the euro in 2011 and 2014, respectively. Lithuania lagged because politicians were reluctant to commit before the 2012 general elections.
Now the government says the switch will provide additional stimulus to the economy - already in better shape than many others in the sluggish eurozone.
But experts warn politicians may be tempted to repeat the mistakes of debt-laden Greece, fuelled by cheap borrowing and poor fiscal discipline.
"There is a risk that politicians may decide euro adoption was the final goal and relax budget policies," said Ramunas Vilpisauskas, director of the Institute of International Relations and Political Science in Vilnius.
Symbol of statehood
Shops and businesses will display prices in both currencies until June.
The two will circulate together as legal tender for two weeks, with the litas converted at a rate of 3.4528.
Lithuania brought in 132 million individual banknotes - standard across the bloc - from the German Bundesbank but minted its own euro coins.
They will feature the national coat of arms, a knight on horseback with sword and shield, which has graced its currency since the 14th Century.
"The national currency has lost its importance as a symbol of statehood amid the spread of e-money and virtual currencies," Vidmantas Laurinavicius, head of the Money museum in Vilnius, told AFP.
The litas helped strengthen Lithuania's statehood when it won back its independence from Moscow in 1918 and 1990, but the currency's role has since diminished.
Lithuanians had sought to immortalise the litas in the Guinness Book of World Records in November by stacking one million coins into the largest coin pyramid ever.
The country's bigger cities will project special videos on New Year's Eve to ring in the euro and bars will offer a non-alcoholic euro cocktail.
