SINGAPORE: The dollar began the last quarter of 2021 near its highest levels of the year, and was headed for its best week since June as investors expected a hawkish-sounding Federal Reserve to lift US interest rates sooner than its major peers.
Cautious market sentiment due to COVID-19 concerns, wobbles in China's growth and a Washington gridlock ahead of a looming deadline to lift the US government's borrowing limit also lent support to the dollar which is seen as a safe-haven asset.
The dollar index stood at 94.287, having gained 1.1% so far this week, the largest weekly rise since late June.
The euro was steady on Friday at $1.1578, but has fallen about 1.3% during the week, and through major support around $1.16, to touch its lowest levels since July 2020.
The yen bounced from a 19-month low overnight but has lost 0.6% for the week and twice as much in a fortnight as a rise in US Treasury yields has drawn flows from Japan into dollars. It last traded at 111.21 per dollar.
Benchmark 10-year Treasury yields are up for a sixth straight week and real 10-year yields, discounted for inflation, are rising far more quickly than counterparts in Europe.
"As long as markets remain confident that the US is going to start tightening monetary policy within a reasonable timeframe, the dollar should remain well," said Societe Generale strategist Kit Juckes.
"The prospect of the European Central Bank keeping rates below zero while the Fed hikes should keep euro/dollar in the post-2014 range, with a centre of gravity around $1.12-1.16," he said.
Commodity currencies made a bounce on the dollar on Thursday following a Bloomberg report which said China had ordered energy companies to secure supplies for the winter at all costs, but were back under pressure on Friday.
Beijing is scrambling to deliver more coal to utilities to restore supply amid a power crunch that has unsettled markets due to the likely hit to economic growth.
The Australian dollar fell 0.3% to $0.7203 and had slumped 3.6% in the third quarter - the worst performance of any G10 currency against the dollar - as prices for Australia's top export, iron ore, fell sharply.
The New Zealand dollar slipped 0.2% to $0.6882.
Central banks in both countries meet next week, with the Reserve Bank of New Zealand seen hiking while the Reserve Bank of Australia is expected to stick with its forecast to keep rates where they are until 2024.
Sterling was also an underperformer last quarter, dropping 2.5%, and looks set to log its worst week in more than a month, weighed down by worries about a hawkish sounding central bank in spite of growing supply chain problems.
Sterling eased 0.2% to trade just above a 9-month low at $1.3452.
Still, some analysts think the dollar might soon lose some momentum. A decline in global COVID-19 cases could see growth rebound by year-end, said Bank of Singapore analyst Moh Siong Sim.
Markets in Hong Kong and China are closed on Friday. Later in the day, traders are awaiting US personal spending and core consumption deflator data and nervously watching for any progress on the debate over raising the US debt ceiling.
A deadline for authorising extra Treasury borrowing looms in mid-October.
