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's business climate index fell to 94.8 this month from 97.5 in July, below the 97.1 forecast, adding to evidence that growth outside the United States is slowing and accelerating the euro's tumble.
"This does not bode well for the second half of the year. The probability of a recession has risen," said Antje Hansen, economist at HSBC Trinkaus.
