The dollar extended its slide today as firm US economic data (claims, retail sales) , an ineffective protest from ECB President Trichet on EUR strength, and a laissez-fair attitude from The Fed’s Fisher helped fuel a break below the closely watched 79.00/05 support level in midday trade.

EUR/USD rallied as high as 1.4817, USD/JPY fell to 88.16 and the dollar index slumped to 75.91.

Rising US bond yields after a worse-than-expected US 30 year bond auction helped bail out the dollar as did the inability of the EUR/USD to overcome key 1.4840/65 resistance and USD/JPY’s failure to challenge the 88.01 lows put in place on Wednesday. DXY techs are muddled as prices rebounded to close above 76.05.

cable was a winner today, boosted by no new QE from the Bank of England, the weak dollar and profit-taking in EUR/GBP as the ECB refrained from signalling it was close to launching any exit strategy. It rebounded toward hugely important resistance at 1.6220/30 before stalling. it closes at 1.6072.

Commodity currencies were the leaders once again with AUD and CAD reaching new highs for the trend. AUD stalled at 90.90 and USD/CAD slipped to 1.0506. 1.0500 barriers are rumored in CAD and at 0.9100 in AUD. Heavy bids are seen in USD/CAD around the 1.0485 level, traders report.

Plenty of USD-buying intervention was seen today with Singapore rumored buying USD/SGD in the US afternoon. Expect bids from central banks on dips, converting some of those intervention proceeds into EUR.
