What made the business news in Asia and Europe this morning? Here's our daily business round-up:
That's up from 10.7% in January and the highest level since the introduction of the single currency in 1999. Spain has the highest rate of 23.6%.
Meanwhile, a separate report confirmed that manufacturing activity in Europe shrank in February.
But Juergen Stark, who resigned last year as the ECB's chief economist, told the BBC's Hard Talk that it was too early to say if Greece will be able to meet its austerity targets.
He said this would be known in six months' time.
The Markit/CIPS Purchasing Managers' Index (PMI) for manufacturing rose to 52.1 last month from 51.5 in February. A reading above 50 implies growth.
The data is an encouraging sign that the UK economy grew in the first three months of 2012 and avoided a recession.
PricewaterhouseCoopers (PwC) and employers' group the CBI found business volumes in the three months to March grew for the eighth quarter in a row.
Optimism in the sector rose for the first time in a year.
Housing equity withdrawal remained negative in the final three months of 2011, the Bank of England said.
The £8.5bn injection of equity reflected low levels of sales, rather than owners making an active effort to pay off their mortgages more quickly.
The Bank of Japan's (BOJ) Tankan survey showed that large manufacturers' sentiment between January to March remained at minus four, the same level as the previous quarter.
The survey is considered by the BOJ while deciding its monetary policy.
You can hear the BBC's interview with ex-ECB chief economist Juergen Stark in the latest edition of our Business Daily programme.
He reveals that he left the bank last year because of deep concern about the ECB's policy of buying the government bonds of indebted eurozone members.
