TOKYO, May 20 ― The US dollar headed for its worst week since early February against major peers today, weighed down by a retreat in Treasury yields and fatigue after the currency's breathless 10 per cent, 14-week surge.

The dollar index, which measures it against six major rivals, was down 1.5 per cent for the week to 102.96, on track to snap a six-week winning run. A week earlier it had soared to the highest since January 2003 at 105.01.

Even with global stocks continuing to slide amid risks to growth from aggressive monetary tightening, led by the Federal Reserve, and China's strict lockdowns to quash a Covid-19 outbreak, the dollar's appeal as a haven was eclipsed by a decline in US yields as investors rushed for the safety of Treasury bonds.

The benchmark 10-year Treasury yield sank overnight to a more than three-week low of 2.772 per cent, from a 3 1/2-year high of over 3.2 per cent earlier this month.

“The dollar was ripe for a pullback,” Edward Moya, senior analyst with OANDA, wrote in a note to clients. “Across the board weakness might continue a while longer.” Other safe haven currencies continued to rally overnight, as a key index of global equities headed for a seventh weekly decline, its longest ever.

The yen headed for a second-straight weekly advance, with the dollar dropping 1.16 per cent to 127.785 yen since last Friday.

The Swiss franc headed for its best week since March 2020, with the dollar falling 2.9 per cent over the period to last trade at 0.97265 franc.

Concerns grew that the Fed and other central banks have fallen behind the curve in combatting super-hot inflation, and will need to be ever more aggressive in tightening policy, inflicting pain on the economy as a consequence.

The war in Ukraine shows no sign of abating either, darkening the outlook for commodity price-driven inflation. China's path out of coronavirus lockdowns also remains unclear, threatening more global price pressures, even as Shanghai prepares to allow more businesses in zero-Covid areas to resume normal operations from the beginning of June.

The Aussie has rallied 1.4 per cent this week and the kiwi has added 1.49 per cent.

Australia's currency slipped today though, down 0.23 per cent to US$0.7031 (RM3.07), as the US dollar bounced a bit after the Aussie's 1.33 per cent surge on Thursday.

“China's strict lockdowns are the main reason why AUD has diverged so much from the level implied by its fundamentals,” Carol Kong, an analyst at Commonwealth Bank of Australia, wrote in a note.

“We remain confident AUD can rebound strongly once lockdowns are eased because of China’s commitment to ramp up infrastructure spending.” New Zealand's kiwi though held all of the previous day's 1.41 per cent jump, ticking up a bit more to US$0.63845. The Reserve Bank of New Zealand sets policy next Wednesday, with expectations for another half-point increase to the key rate.

The euro edged 0.07 per cent lower today to US$1.05735, but was still on course for a 1.55 per cent weekly gain.

Sterling slipped 0.07 per cent to US$1.24615, but was up 1.66 per cent for the week, its best showing since late 2020.

Westpac analysts warned not to count the dollar out, even if its rally was “losing some of its vitality”.

“It’s still far too early to call a long-term peak, amid unsettled global market conditions and a resolute Fed,” the Australian bank's analysts wrote in a research note, recommending buying on dips in the 102s and targeting 105 multi-week. ― Reuters
