Eurostat, the European Union's statistics agency, revealed that the economies of both the eurozone and the wider 27-country EU shrank by a quarterly rate of 0.2 per cent in the second quarter of the year. In the first quarter, output for both regions was flat. A recession is officially defined as two straight quarters of falling output.
Europe's stumbling economy is making it harder for other economies around the world to recover and policymakers from all round the world are urging more decisive action, particularly from the European Central Bank, to deal with the crippling debt crisis to restore confidence to the global economy.
"The ECB's recent announcement that it will do 'whatever it takes' to save the euro is welcome, but clarity over what will be done is crucial," said Tom Rogers, a senior economic adviser for accounting firm Ernst & Young.
The region is the U.S.'s largest export customer and any fall-off in demand will hit order books — as well as President Barack Obama's election prospects.
The eurozone is grappling with sky-high debt levels and record unemployment of 11.2 per cent. Compared with the year before, the eurozone's economy is 0.4 per cent smaller.
Without Germany continuing to post solid levels of growth, the eurozone would officially be in recession.
Europe's largest economy grew by a quarterly rate of 0.3 per cent in the second quarter. Though down on the 0.5 per cent recorded in the first quarter, the advance was a little more than expected — most economists thought Germany would only grow by 0.2 per cent.
Though Germany currently benefits from strong demand for its products, its high-value exporters are finding it increasingly difficult to tap international markets. Forward-looking surveys, including Tuesday's closely-monitored ZEW survey of German investor sentiment, are suggesting that confidence is taking a knock as Europe moves from one crisis point to another.
The other 16 countries that use the euro are Germany's biggest export market and six of them are in recession. The U.S. is also coming off the boil, with growth in the second quarter down compared to the previous three months at 0.4 per cent, according to Eurostat.
Slower economic growth is also making it harder for governments and central banks to control the debt crisis in Europe. Shrinking economies make it more difficult to get the public finances into shape. Lower output dents tax revenues while forcing up the cost of social benefits.
"The big picture is that the economic growth required to bring the region's debt crisis to an end is still nowhere in sight," said Jonathan Loynes, chief European economist at Capital Economics.
For those countries at the front-line of Europe's debt crisis, the figures make for grim reading. Unsurprisingly, Greece is faring the worst — its economy is 6.2 per cent smaller than a year ago and back at the level it was in 2005.
Portugal, which has also been bailed out and enacting the tough austerity medicine, suffered a big 1.2 per cent drop in output in the second quarter, compared with the previous quarter's modest 0.1 per cent drop.
Italy and Spain, the eurozone's third and fourth largest economies, shrank by 0.7 per cent and 0.4 per cent respectively in the second quarter. Both countries are struggling to convince markets they have a strategy to get a grip on their debts. Spain has even acceded to a bailout of its banks.
Alexander Schumann, chief economist at The Association of German Chambers of Industry and Commerce, urged Europe's indebted countries to carry on with their reforms and that it won't be long before they start reaping the rewards.
"We need to be patient but there are positive signs that in 18 or 24 months we might see light at the end of the tunnel in Portugal, Spain, Italy and Greece, "he said. "We can get there if politicians don't block the tunnel with ideas that add new uncertainty."
