The brief intervention by Japanese authorities is losing its effect, prompting strategists to forecast a recovery in the Australian dollar against the Japanese yen back toward multi-decade highs, supported by the Reserve Bank of Australia's hawkish stance.

The currency pair, which slumped over 4% to near the 109 level following Japan's market intervention, has now entered a recovery phase, closing last week at 111.52. This rebound suggests that the official measures provided only temporary support for the yen, particularly against higher-yielding currencies. With the RBA's next policy decision approaching, analysts are increasingly confident that interest rate differentials will outweigh any further intervention from Tokyo.

"The adjustment on the yen side is largely complete," said Mahabin Zaman, Head of Foreign Exchange Research at ANZ Group. She noted that the likelihood of further unilateral Japanese intervention is low, given clear signals from the US regarding potential coordinated action. On the Australian dollar front, Zaman expects the RBA to maintain a hawkish tone amid geopolitical uncertainties and volatile energy prices. "Improved commodity trade terms will support the Australian dollar, keeping it resilient in cross trades."

This shift in sentiment is already visible in the derivatives market. Over the past week, the premium for one-month options hedging a decline in the Aussie-yen pair has fallen sharply, indicating that traders are gradually abandoning bearish bets. AT Global Markets Australia predicts that if no new yen-support measures emerge from Japan or the US in the near term, the pair will recover to levels seen in late July. "Improving geopolitical sentiment could further boost the Australian dollar," said Nick Twidell, Chief Market Analyst. "The initial target is 113.38, the July 29 low, with stronger resistance near the year's high of 114.80." He pointed to interest rate differentials as the key driver behind the pair's earlier push toward 115.

Traders are now focused on the RBA's rate decision scheduled for August 11. While the market widely expects the central bank to hold rates steady, swaps markets still price in roughly a 50% chance of a 25-basis-point rate hike by year-end. This expectation is supported by RBA Governor Michele Bullock's recent comments, where she confirmed that policymakers would not hesitate to raise rates further if necessary.

However, not all market participants believe the RBA's stance will sustain a prolonged rally for the Australian dollar. Samara Hamoud, a currency strategist at Commonwealth Bank of Australia, cautioned that once the recent correction is fully repaired, the upside for the Aussie-yen pair is limited. She expects the cross rate to fall back to 108 by the end of the quarter. Hamoud forecasts the RBA will keep rates unchanged this year before starting a rate-cutting cycle, while the Australian dollar will also face additional pressure from a broadly stronger US dollar.

Other analysts, however, argue that the macro environment remains favorable for the Australian dollar. "The RBA is likely to maintain a hawkish stance next week, and as the intervention effect fades, this supports the Aussie-yen pair," said David Forrester, Senior Foreign Exchange Strategist at Credit Agricole.
