LONDON, Aug 26 (Reuters) - World stocks hit their lowest level in almost two years on Tuesday as a worsening German business mood and fresh concerns about financial firms triggered a sell-off in risky assets, lifting the dollar to a 2008 high.
The Munich-based Ifo economic research institute said its business climate index fell to 94.8 this month from 97.5 in July, worse than the 97.1 consensus forecast, adding to growing evidence that growth outside the United States is deteriorating and accelerating the euro's tumble.
"The data should be considered dramatic," said Folker Hellmeyer, economist at Bremer Landesbank.
"I expect the global slowdown will continue and affect Germany significantly more than has been reflected in forecasts up to now."

U.S. regulators closed Columbian Bank and Trust on Friday, the ninth U.S. bank to fail this year as the weakening economy and falling home prices take their toll on financial firms.
While the epicentre of the one-year-old credit crisis lies in the United States, investors eyed worsening growth elsewhere, which benefited the dollar across the board at the expense of high-yielding peers such as the Australian dollar.
"Problems in the U.S. financial market are leading to equity market weakness which is the principal driver hitting the high- yielding currencies," said Daragh Maher, deputy head of global foreign exchange research at Calyon.
