Published by Mark Smith-HalvorsenThe euro strengthened in foreign exchange trading overnight as investors readjusted record short positions on the single currency against the dollar.Meanwhile, the greenback also lost ground against the yen and the pound, with forex hedging strategists deciding that the latter's slump was out of line with fundamentals.But while the euro continued to climb this morning (March 3rd), there is possibility that the market may grow jittery as the full extent of the challenges ahead of Greece become clear as it attempts to rein in its debts become clear.Speaking to Bloomberg on condition of anonymity, an official familiar with the matter claimed that the country's prime minister George Papandreou is finding new holes in the budget every day and is planning swathing cuts to comply with EU demands."We need the support of our partners.
