Germany's consumer sentiment index for August edged down to minus 29.6 from minus 29.3 in the previous month. The figure, released by the Nuremberg Institute for Market Decisions and GfK, came in below the minus 28.5 forecast by analysts polled by Reuters. As the outlook for income turned more pessimistic, households remained cautious about spending, and the propensity to save rose slightly again. While willingness to buy picked up modestly, it remains at a low level, weighed down by uncertainty about the future.
