Dollar springs back in London

The dollar rose against the euro and growth-linked currencies on Thursday after the US Federal Reserve disappointed investors who had expected it to opt for more aggressive easing - a move that would have boosted appetite for riskier currencies. The euro came under fresh pressure after data showed Germany's private sector shrank in June for the second month running, with manufacturing activity hitting a three-year low.
"After the Fed there was a bit of disappointment for the market but at least they extended Operation Twist," said Lutz Karpowitz, currency strategist at Commerzbank. The euro dropped 0.2 percent to $1.2674, having hit a high of $1.2744 on Wednesday. Bids from sovereign investors and macro funds were cited below $1.2620. Offers were reported above $1.2700 and stop-loss orders above $1.2720, traders said.
The dollar regained lost ground after the Fed stopped short of launching a more aggressive programme of buying bonds outright, or QE3, which some in the market had expected. Policymakers expanded "Operation Twist", under which the Fed sells short-term securities to buy longer-term ones to keep long-term borrowing costs down, by $267 billion. The programme, which was due to expire this month, will run until the end of the year.
The dollar index, a measure of the greenback's performance against a basket of currencies, rose 0.1 percent to 81.595. The dollar rose to a 1-month high at 79.958 yen, getting some support after US Treasury yields edged up on Wednesday. Analysts said the dollar's outlook was clouded, with more players likely to position for fresh Fed stimulus after the central bank downgraded its US growth forecast. Many analysts said the Fed was probably saving ammunition given the risk the euro zone crisis could deteriorate in coming weeks as borrowing costs in peripheral countries remain high.
Growth-linked currencies came under pressure, digesting the Fed decision and weak Chinese data. The Australian dollar fell 0.2 percent to $1.0170, retreating from a seven-week high of $1.0225 hit on Wednesday. The Aussie dollar hit an intraday low after a private-sector survey showed China's factory sector contracted for an eighth successive month in June, with export orders at their weakest since early 2009.
