MADRID (Reuters) - The Spanish economy is falling deeper into recession and depositors are pulling their money out of the banks, figures published on Tuesday showed, while the country's most economically important region, Catalonia, said it needed a major rescue from Madrid.

Spain's recession grew stronger in the second quarter of the year and is expected to get worse as austerity measures introduced in response to the euro zone debt crisis cut into demand for goods and services.

A rush by consumers and firms to withdraw their money from Spanish banks intensified in July, with private sector deposits falling almost 5 percent, to 1.509 trillion euros ($1.896 trillion) at end-July from 1.583 trillion a month earlier.

Analysts believe it is inevitable that Spain will soon have to call for a European rescue package to help bring its debt costs down as austerity measures designed to slash the public deficit push the economy deeper into recession.

Adding to Spain's bleak outlook, the north-eastern region of Catalonia, which represents around a fifth of the country's economy, said it needed a 5 billion euro rescue from the central government to meet its financing needs and debt costs this year.

Against this background European Council President Herman Van Rompuy said it was up to Spain to decide whether to apply for additional aid, after meeting with Prime Minister Mariano Rajoy in Madrid. Rajoy repeated that he needed more details from the European Central Bank to help him decide.

Their meeting came a week before the ECB discusses new measures to help debt costs in the European nations hardest-hit by the crisis. The ECB meeting on September 6 also coincides with a visit by German Chancellor Angela Merkel to the Spanish capital and a key longer-term bond auction.

"With much more fiscal austerity in the pipeline and unemployment at astronomic highs, the risks are clearly tilted towards a more protracted recession," said Martin van Vliet, an economist at ING.

He expected Spain to formally request additional external financing in mid-September or October. Spain has already negotiated up to 100 billion euros in aid for its ailing banks.

Gross domestic product fell by 0.4 percent in the second quarter of the year, according to final figures that confirmed a preliminary reading. But on an annual basis it dropped by 1.3 percent, worse than initial estimates of 1.0 percent.

BLOATED DEFICIT

Spain's economy fell back into recession in the last quarter of 2011, when output fell 0.5 percent, and government estimates show GDP will probably fall this year and next.

The data came a day after Spain said its economy performed worse than expected in both of the last two years.

Economists said the outlook could test Spain's ability to slash its deficit this year to 6.3 percent from 8.9 percent in 2011.

"The economy is much weaker than previously thought and this could make it more challenging for the government to achieve the ambitious fiscal targets," said Tullia Bucco, an economist at UniCredit.

Tuesday's data showed exports provided a degree of support for the economy, growing by 3.3 percent year-on-year in the second quarter. That compared with a fall of 3.9 percent in national demand, after a revised fall of 3.2 percent in the first quarter.

The government is hoping that exports will put the economy on the road to recovery. But a slowdown in the wider euro zone, where most of Spain's goods are shipped, could put that theory at risk.

Tourism, which makes up over 10 percent of Spain's economic output, provided a welcome boost, as spending increased by more than 6 percent from January to July to 31.2 billion euros.

Also encouragingly, the Treasury managed to sell 3.6 billion euros of short-term debt, and paid far less to investors than a month ago.

The yield on the 3-month bill was 0.946 percent, down from 2.434 percent a month ago, and was 2.026 percent on the 6-month bill, down from 3.691 percent in July.

The fall partly reflects growing market expectations that Spain will soon call for a European bailout. But exactly when remains unclear, and investors will watch the European Central Bank's meeting next week for measures to relieve Spain's debt costs.

"The real test begins next month when sentiment could worsen significantly if ECB-backed measures to shore up Spanish and Italian debt markets fall short of expectations," said Nicholas Spiro at Spiro Sovereign Strategy. ($1 = 0.7990 euros)
