Key Takeaways
The Australian dollar surged 1.2% against the greenback on Thursday after suspected currency intervention by Japanese authorities to bolster the yen triggered a broad US dollar selloff.
"It's pretty obvious given the discussion from the ministry of finance about potential intervention," said John Velis, Americas macro strategist at BNY Mellon. "The fact that the yen was in its own world... the intervention is pretty understandable."
The move came after the dollar fell by as much as 3% against the Japanese currency to 155.5 yen, its largest single-day drop since late 2024, according to Reuters. The broader dollar index, which measures the greenback against a basket of currencies, slid 0.80% to 98.06, snapping two straight sessions of gains. The yen's surge lifted other major currencies, with the euro rising 0.51% to $1.1733.
The intervention temporarily eases pressure on currencies like the Aussie, which are sensitive to US dollar strength, but its lasting success is uncertain. "Past intervention has had only a temporary effect on the yen if the underlying fundamentals haven't shifted," Kristina Clifton, a senior currency strategist at Commonwealth Bank of Australia, wrote in a note. The focus now shifts to whether Japanese officials will act again and to the Bank of Japan's next meeting in June for signals on a potential rate hike.
Japanese officials had been issuing increasingly strong warnings as the yen slid to its weakest level against the dollar since July 2024. Finance Minister Satsuki Katayama said earlier Thursday that the time for "decisive" action was nearing, just before the sharp reversal in the dollar-yen rate during London trading hours.
The broad-based dollar weakness provided a tailwind for the Australian dollar, which is sensitive to shifts in risk appetite and global commodity prices. The initial report from Forex.com noted the Aussie was moving back towards its range highs, with the near-term setup favoring further upside, especially if Japanese authorities were to intervene again.
"The weak yen is probably there for a reason and how successful the MOF will be in fighting against the tide on a sustained basis is sort of hard to see at the moment," said Ken Crompton, the head of rates strategy at National Australia Bank.
