The euro sank to a new five-week trough after Russia announced a three-day halt to European gas supplies via the Nord Stream 1 pipeline at the end of this month, exacerbating the region's energy crisis. China's yuan dropped to its lowest in nearly two years after the central bank cut key lending rates, adding to a string of monetary easing measures aimed at shoring up an economy reeling from COVID-19 clampdowns and a property crisis. The Australian and New Zealand dollars rebounded strongly from near five-week lows, helped by firmer commodity prices. The U.S. dollar index, which measures the currency against six rivals including the euro, edged up to 108.26 for the first time since July 15 early in the Asian session before trading flat at 108.12. It gained 2.33% last weekits best weekly rally since April 2020amid a chorus of Fed policymakers stressing that more needs to be done to rein in decades-high inflation. The latest was Richmond Fed President Thomas Barkin on Friday, saying the "urge" among central bankers was towards faster, front-loaded rate increases. "Fed speakers have been stressing the message that more rate hikes are coming given the fight against inflation has not yet been won," rattling markets ahead of Jackson Hole on Aug. 25-27, amid growing expectations for Fed Chair Jerome Powell to stress that tightening is "still a long way from the end," Rodrigo Catril, senior FX strategist at National Australia Bank (OTC:NABZY), wrote in a client note. Money markets currently indicate 46.5% odds for another supersized 75 basis point rate hike on Sept. 21, with a 53.5% chance for a half-point rise. Economists in a poll lean toward a 50 basis-point increase with recession risks on the rise. Benchmark 10-year U.S. Treasury yields rose above 3% on Monday for the first time since July 21. Against Japan's currency, which is extremely sensitive to U.S. yields, the dollar climbed as high as 137.44 yen, the strongest since July 27. The dollar rose as high as 6.8308 yuan in onshore trading for the first time since September 2020 after the People's Bank of China cut the one- and five-year loan prime rates, as widely expected. That came after it eased other key borrowing benchmarks in a surprise move last week. Against the offshore yuan, the dollar hit 6.8520, also the strongest since September 2020. The commodity-linked Aussie gained 0.39% to $0.6902rebounding after a slide to $0.68595 on Friday for the first time since July 19as Dalian iron ore rallied more than 2% and copper also rose. The kiwi advanced 0.4% to $0.61995 after declining to $0.61675 at the end of last week, also a first since July 19. Meanwhile, the euro dipped as low as $1.0026 for the first time since July 15 before trading flat at $1.0040. Sterling was little changed at $1.18325, remaining not far from Friday's five-week low of $1.17925. Bundesbank President Joachim Nagel told German newspaper Rheinischen Post that the German economy, among the most exposed to disruptions in Russian gas supply, is "likely" to suffer a recession over the winter if the energy crisis continues to deepen. But he added that even if a German recession is increasingly probable, the European Central Bank must keep raising rates to tame inflation. "Time back below parity looks inevitable" for the euro, although it may bounce around either side of that mark in the short term rather than falling strongly through it, Westpac strategists wrote in a research note.
