The dollar fell back against other major currencies on Thursday, hit by speculation US Federal Reserve chief Janet Yellen will express concern over the pace of its surge to a 13 1/2-year high in the past week and an accompanying rise in bond yields. The dollar has ground its way higher this week after jumping in the days following Donald Trump's victory in the US presidential election last Tuesday, fuelled by expectations a Trump White House would drive up inflation.
But with two months until his inauguration and a rise in Fed interest rates now fully priced in for next month, several banks say the currency could drift. Valentin Marinov, head of G10 FX strategy at Credit Agricole in London, said that Fed speakers this week had sounded divided on their view on the effective tightening of monetary conditions since Trump's election. "All eyes are on Yellen today," he said.
"She may not share markets' enthusiasm about the future impact of Trump's policies. And she could express concern about the dollar's rapid gains and the tightening of conditions through higher bond yields. That could spur some profit-taking on the bullish dollar positions."
Traders said prepared remarks released ahead of the session in Congress, due to start at 1500 GMT, gave a measured view that showed no sign of the Fed chair growing more bullish on inflation and rates next year, even as she pointed to the likelihood of a rise in rates "relatively soon".
That played in to a subdued mood in Europe around the greenback, down around a third of percent against the basket of currencies that measures its broader strength from almost 14-year highs hit on Wednesday. It was 0.2 percent higher on the day at 109.03 yen but lower against the euro at $1.0716.
"I have been long the dollar against the euro for three days," said Louis Gargour, chief investment officer with hedge fund LNG Capital in London. "$1.05 is not out of the question. Will I be in the trade that long (until Trump's inauguration), maybe not. Let's look at the cabinet, let's look at who he puts in place and whether his policy will be as good (for the dollar) as people expect."
The yen took a knock overnight when the Bank of Japan conducted its first special operation to curb rising yields on Japanese government bonds (JGBs). The offer was priced to attract no bids, but knocked government bond yields further back into negative territory, pushing the dollar briefly as high as 109.30 yen.
"When the Japanese bank is promising to buy effectively as many bonds as need be, printing more yen to do so, then there does seem to be a clear perspective for a weaker yen," Didier Saint-Georges, a director with French asset manager Carmignac Gestion, told Reuters' annual investment summit in London. The US benchmark 10-year Treasury yield is now at 2.199 percent, after reaching a 10-month high of 2.302 percent earlier in the week.
