The AUD/JPY carry trade has been one of the most watched positions in G10 forex for decades. You borrow in low-yielding yen, park the money in higher-yielding AUD, and collect the interest rate differential while hoping the exchange rate doesn’t move against you. Simple in theory. In practice, it’s a trade that periodically blows up in spectacular fashion.

As we head into Q2 2026, the carry trade dynamics have shifted enough to warrant a fresh look. Let me walk through where things stand.

The Current Rate Differential

The RBA cash rate sits at 3.85% after holding steady through Q1. The Bank of Japan’s policy rate is at 0.75%, having been raised incrementally from zero through 2024 and 2025. That gives us a nominal rate differential of 310 basis points.

That’s narrower than it was in mid-2024 when the differential peaked above 400 basis points. The compression has come from both sides — the RBA cutting from 4.35% and the BOJ hiking from zero. But 310 basis points is still meaningful carry, especially in a world where many G10 pairs offer much less.

The annualised carry on a standard AUD/JPY position (after adjusting for the forward points implied by the rate differential) is currently running at approximately 2.8%. That’s not spectacular, but it’s positive income while you sleep. The question, as always, is whether the exchange rate risk justifies the carry income.

What’s Changed Since the August 2024 Unwind

The carry trade unwind in August 2024 remains seared into every AUD/JPY trader’s memory. When the BOJ surprised with a larger-than-expected rate hike and hinted at more to come, the yen rallied violently. AUD/JPY dropped from around 109 to 93 in a matter of weeks. Carry traders who’d accumulated leveraged positions got crushed.

Several things have changed since then.

First, the BOJ has been remarkably transparent about its intentions through 2025 and into 2026. Governor Ueda has established a pattern of clear forward guidance, and the market has largely priced in the expected path of Japanese rates. That reduces — though doesn’t eliminate — the risk of a BOJ surprise.

Second, AUD/JPY positioning has been far less extreme than it was pre-August 2024. CFTC data shows speculative yen short positions (the flip side of carry trades) are currently about 40% of their July 2024 peak. The trade is popular but not dangerously crowded.

Third, the implied volatility on AUD/JPY options has settled into a lower range. Three-month implied vol is around 10.5%, compared to the spike above 20% during the August 2024 unwind. Options market pricing suggests the market isn’t expecting another violent move.

The Risk Factors for Q2

That said, there are specific risks heading into Q2 that carry traders need to monitor.

BOJ policy risk. The BOJ’s April meeting coincides with the release of its updated Outlook Report, which includes revised growth and inflation forecasts. If the BOJ upgrades its inflation outlook and signals a faster pace of normalisation, yen could rally sharply. The market currently prices roughly one more 25 basis point hike by year-end. If that expectation shifts to two hikes, the carry trade math changes meaningfully.

Chinese economic data. AUD is fundamentally a China proxy in forex markets. If Chinese economic data deteriorates through Q2 — and there are warning signs in the property sector and consumer spending data — AUD could weaken independently of the carry dynamic. A falling AUD/JPY rate can overwhelm carry income quickly.

Risk sentiment broadly. Carry trades perform best in low-volatility, risk-on environments. If global equity markets correct, or if geopolitical risks escalate, the carry trade unwind can be self-reinforcing. Traders sell AUD and buy yen as a risk-off response, which pushes AUD/JPY lower, which triggers more unwinds. It’s the same dynamic that’s played out in every carry trade blowup since the late 1990s.

Seasonal patterns. There’s a documented tendency for AUD/JPY to weaken in April-May as Japanese fiscal year-end flows (in March) complete and domestic Japanese investors repatriate foreign holdings. It’s not a reliable seasonal trade on its own, but it’s a headwind worth noting.

The Positioning Decision

For traders considering AUD/JPY carry exposure into Q2, the framework I’d suggest is straightforward.

The carry is positive but modest. At 2.8% annualised, you need AUD/JPY to stay flat or rise to profit. A move of more than about 2 yen against you wipes out a quarter’s carry income. Given current volatility, a 2-yen move is well within normal range.

Position sizing matters more than direction. Carry trades blow up when they’re overleveraged. At conservative sizing — 2:1 or 3:1 leverage — the carry is nice but not exciting. At 10:1 or higher, you’re taking a binary bet on risk sentiment with a small yield kicker.

Hedging with options is worth considering. Buying a put option on AUD/JPY at a strike 3-5% below current levels provides catastrophic loss protection while preserving the carry. The cost of that protection reduces your net carry, but it means you can size the position more aggressively.

My read is that AUD/JPY carry is a reasonable position in Q2 if sized conservatively and hedged against tail risk. The structural forces supporting it — positive rate differential, contained BOJ policy risk, moderate positioning — are intact. But the narrower differential compared to 2024 means the margin for error is thinner.

Don’t get greedy. The yen has a long history of punishing those who do.
