PAN PYLASLONDON (AP) â¿¿ A deal to give Greece more cash was greeted with measured relief Tuesday, though concerns remained over the country's ability to implement its required reforms as the economy shrinks. In the early hours of Tuesday, Greece's euro partners and the International Monetary Fund agreed to release vital loan payments totaling some â¿¬44 billion ($57 billion) and introduce a series of measures designed to reduce the country's massive debts to a more manageable level within a decade. These include reducing the interest rates Greece has to pay on the loans and a still-vague bond buyback program. Though the deal avoids an imminent bankruptcy of Greece, the country still has to implement wide-ranging cuts and reforms in the months and years ahead. Many in the markets think that will be too much for a country that's about to enter its sixth year of recession and a society struggling to cope with rising poverty levels and an unemployment rate of 25 percent. "Clearly Greece undoubtedly has the capacity to throw further bad news over the coming months and years although for now such risks should be laid low meaning that the eurozone crisis should remain off the boil into year end," said Jane Foley, an analyst at Rabobank International. In Europe, the FTSE 100 index of leading British shares rose 0.2 percent to close at 5,799.71 while Germany's DAX rose 0.6 percent to 7,332.33. The CAC-40 in France ended flat at 3,502.13. The rally in Athens was minimal, with the main index up only 0.3 percent as investors had hoped for a little more debt relief from the deal. The euro also gave up some earlier gains to trade 0.2 percent lower at $1.2945. In the U.S., stocks were underperforming as investors fretted again over the prospects of a budget deal between the White House and lawmakers to avoid the so-called "fiscal cliff" of automatic tax increases and spending cuts at the start of next year. Those concerns more than offset a rise in a closely-watched measure of consumer confidence â¿¿ the Conference Board's main index rose to 73.7, its highest level since Feb. 2008.
