- AUD/JPY rose for seven straight sessions but slipped about 0.2% today as the yen strengthened on intervention fears and BoJ hike expectations
- Japan and the US conducted a rare coordinated yen-buying intervention in early August, the first such joint action since 2011
- The wide Australia-Japan interest-rate gap still underpins the carry trade. However, there is a rising likelihood of a near-term volatility from policy signals
The Australian dollar’s recent upward trend against the Japanese yen has been a significant topic in foreign exchange markets. A seven-session winning streak is a notable achievement for any currency pair, particularly one often viewed as an indicator of market risk sentiment.
However, this streak ended today. The AUD/JPY pair saw a decline of approximately 0.2% during New York trading, settling around 112.37 compared to a previous close of 112.60. This shift raises questions about the underlying causes and whether this marks a more substantial change or a temporary pullback.
Yen Intervention Risk Hasn’t Gone Away
The most important piece of context here is what happened just two weeks ago. Japan and the United States confirmed a rare, coordinated yen-buying intervention, aiming to stop the currency’s slide to 40-year lows. Tokyo signaled it’s ready to act again if needed.
This wasn’t just any intervention. It was the first joint effort since 2011, and the market can’t simply ignore it. US Treasury Secretary Scott Bessent reinforced that message, stating Washington “won’t hesitate to participate in further joint intervention.” He also pushed for more rate hikes from the Bank of Japan. That combination creates a persistent headwind for anyone holding long AUD/JPY positions.
The yen also strengthened after traders looked at the Bank of Japan’s recent Summary of Opinions. BoJ members pointed out growing risks of domestic inflation, leading some to think that Japanese officials might raise interest rates again, possibly in September.
What Does This Mean for the Carry Trade?
AUD/JPY has long been a favourite among carry traders. AUD/JPY has long been a favorite among carry traders. This strategy works best when Australian rates stay high (or rise) and the yen remains weak and stable. Today’s price action suggests both pillars are wobbling a bit.
It looks like the period of easy gains during the rally might be turning into a trading range. As the BoJ moves closer to normalizing its policies and yields on long-term Japanese government bonds rise, the net return from the interest rate difference becomes less protected from sudden currency dips.
How to Position From Here?
None of this necessarily signals the rally is over. Seven consecutive days of gains represent a strong upward move, and a single 0.2% dip is within the normal range for profit-taking. However, traders should now consider the risk of intervention as a consistent element for this currency pair, rather than an isolated event.
This suggests adopting tighter stop-losses and smaller position sizes for any new long entries, rather than aggressively pursuing new highs. Longer-term investors who can tolerate market fluctuations may still find the interest rate differential appealing. It is advisable to maintain strict stop-losses around upcoming speeches by Reserve Bank of Australia officials and releases of Japanese inflation data to mitigate potential volatility.
The Japanese yen got a slight lift today. New intervention warnings surfaced, and people are increasingly expecting a Bank of Japan rate hike this September.
Australia’s cash rate is higher than Japan’s policy rate, creating a big interest-rate difference. This still makes holding the Australian dollar attractive.
That coordinated action in late July did give the yen a short-term boost, but its impact has mostly faded. The carry trade now looks attractive once more.
