Concerns over fears of "double dip" in US house prices, weighing on sentiment and could trigger more risk aversion. UK Independent : The ailing US housing market passed a grim milestone in Q1 this year, posting a further fall that means fall in house prices is now greater than that suffered during Great Depression. The brief recovery in 2009, spurred by govt aid to first-time buyers, has now been entirely snuffed out, average US home now costs 33% less than at peak of housing bubble in 2007. The peak-to-trough fall in the 1930s Depression was 31%- and prices took 19 years to recover after that downturn. Latest Case-Shiller house price index was just one of disappointing economic data. On FX, good to watch the above and impact on stocks (though stock prices up yest, Dow +1.03%, S&P +1.06%). GBP at 1.6467-70, offers 1.6500, eye 1.6350. USD/CHF at 0.8525-30, eye all time lows 0.8467 on risk aversion again. WL
