The dollar held near its highest levels of the past week in Asian trading on Friday as renewed fears of energy supply disruptions in the Middle East pushed up bond yields and oil prices.
The US dollar index, which measures the greenback's strength against a basket of six currencies, was trading flat at 99.084, after strengthening to its highest level since September 7 during the previous session. The rise followed the release of data showing US producer prices increased 0.4% in August, meeting market expectations as energy prices rebounded during the month.
"The safe-haven US dollar gained on risk-aversion flows, helped by higher energy prices that have lifted the chance of a Fed hike next week to 70%," said Tony Sycamore, market analyst at IG in Sydney.
Energy prices snapped a five-day gaining streak, with Brent crude futures down 0.6% at $106.99 a barrel in Asian trade.
But both major benchmarks remained above the $100 mark earlier this week, with WTI futures surging across the threshold on Thursday for the first time since May 21.
Against the yen, the US dollar was down 0.2% at 154.105 yen and on track for its second consecutive week of declines, while the euro slipped 0.2% to 178.99 yen after the European Central Bank hiked interest rates on Thursday for the second time this year.
The Japanese currency regained some strength after data released on Friday showed wholesale inflation rose 7.6% in August from a year earlier, bolstering the case for a rate hike this month.
The Bank of Japan is set to raise interest rates next week, most likely by 25 basis points, and may signal faster future tightening if price pressures heighten risks of an inflation overshoot, four sources familiar with its thinking told Reuters.
The kiwi dollar was up 0.5% at $0.5827, retracing a selloff on Thursday that has put the currency on track for its third week of declines. New Zealand's 10-year government bond yields rose by 15.5 basis points to 5.06% on Friday, extending the biggest two-day jump in borrowing costs since last year's "Liberation Day" selloff.
"New Zealand seems to have been hit harder than most in the latest leg of the bond market sell-off," said Thomas Mathews, head of markets for Asia Pacific at Capital Economics in Wellington.
The Australian dollar was up 0.2% at $0.7167.
Both the euro and the British pound were level against the dollar at $1.1609 and $1.3503, respectively.
PRESSURE BUILDS ON FEDERAL RESERVE
Markets are awaiting the release of US CPI later on Friday, one of the last major economic data points released before the Federal Reserve meets next week.
Fed funds futures are pricing an implied 71.1% probability of a 25-basis-point hike at the US central bank's next two-day meeting ending on September 16, compared with a 61.2% chance in the previous trading session, according to the CME Group's FedWatch tool.
Fixed-income markets remained uneasy after the US Treasury Department tripled the size of its long-dated bond repurchase, with a gauge of bond volatility rising to its highest level in a month. The yield on US 10-year government bonds was up 1.5 basis points at 4.957%.
"10-year US Treasury yields are within striking distance of 5%, as the markets have reassessed the Fed's path higher while term premium is appropriately hovering near pre-GFC levels," Barclays analysts wrote. "We remain of the view that bonds are not cheap yet and catalysts for a rally do not appear imminent."
In cryptocurrencies, bitcoin was down 0.2% at $77,094.41 while ether was 0.1% lower at $2,457.96.
