Why G10 Carry Trades Are Surging in 2026

Wide Interest‑Rate Differentials Are the Core Driver

Interest‑rate divergence among developed economies has been unusually large compared with the near‑zero‑rate environment seen during the COVID‑19 era. When central banks maintain different policy paths, the yield advantage of certain currencies becomes more attractive.

This has encouraged investors to fund positions using lower‑yield currencies—most prominently the Japanese yen—while buying currencies where interest rates remain higher. The resulting yield pickup is the fundamental source of carry‑trade profits.

Low FX Volatility Makes the Strategy Work

Carry trades can quickly lose money if exchange rates move sharply against the position. Because of that, volatility is often the biggest threat to the strategy.

In 2026, currency markets have been unusually calm despite geopolitical tensions. Lower volatility means the interest income earned from rate differentials is less likely to be erased by sudden exchange‑rate swings. Analysts have noted that sustained low volatility tends to favor carry strategies across major currencies.

Why AUD, NOK, and GBP Have Outperformed

The rally has been amplified because several higher‑yield or pro‑cyclical currencies have also appreciated.

Among the strongest contributors:

• Australian dollar (AUD) – often supported by relatively higher yields and global growth exposure.
• Norwegian krone (NOK) – tied partly to energy markets and benefiting from commodity dynamics.
• British pound (GBP) – supported by comparatively higher policy rates within the G10.

When these currencies rise against funding currencies, investors gain both the interest spread and the exchange‑rate appreciation—significantly boosting total carry returns.

The Yen’s Muted Safe‑Haven Role

Historically, the Japanese yen acts as a major safe‑haven currency, often strengthening during geopolitical shocks or market stress. Safe‑haven currencies such as the yen, Swiss franc, and U.S. dollar typically appreciate in risk‑off environments as investors seek stability.

But during the 2026 Middle East tensions linked to the Iran conflict, the yen did not rally as strongly as usual. Reports noted that the U.S. dollar gained safe‑haven demand while the yen traded more steadily rather than surging.

That matters because a sharp yen rally is one of the classic triggers for carry‑trade unwinds. If the funding currency strengthens rapidly, investors must close positions, which can amplify market volatility. In 2026, that squeeze largely failed to materialize, allowing the carry trade to continue performing well.

Why Geopolitical Risk Hasn’t Broken the Trade

The presence of geopolitical tensions—including the Iran conflict—has not been enough to disrupt the carry rally. Markets have experienced risk events, but not the sustained volatility or safe‑haven surge that normally forces carry traders to exit positions.

As a result, investors have continued prioritizing yield opportunities over defensive positioning.

The Risks That Could End the Rally

Despite strong recent performance, carry trades remain inherently fragile. The same leverage and positioning that boost returns can accelerate losses if conditions change.

Three risks stand out:

1. A spike in FX volatility
Sudden currency swings can quickly overwhelm the interest‑rate advantage that carry trades depend on.

2. An oil‑price shock
Escalating Middle East tensions could push energy prices higher. While this might support oil‑linked currencies like the Norwegian krone, it could also trigger broader inflation fears and risk aversion.

3. Global recession fears
Carry trades rely heavily on investor risk appetite. If economic growth weakens, markets often shift toward safe‑haven currencies and away from higher‑yielding ones.

The Bottom Line

The surge in G10 currency carry trades in 2026 reflects an unusually favorable combination of wide interest‑rate gaps, low FX volatility, and strong performance from higher‑yield currencies. At the same time, the Japanese yen’s limited safe‑haven rally during geopolitical tensions has reduced the risk of sudden position unwinds.

However, the conditions supporting the trade are inherently fragile. A volatility shock, a sharp oil‑price surge, or rising recession fears could quickly reverse the trend and expose how dependent carry strategies are on calm and stable markets.
