What’s the likelihood of Yen carry trade reversing?
A UBS research report indicates that a significant reversal of the yen carry trade is highly improbable, despite recent increases in Japanese government bond yields.

The article examines the stability of the yen carry trade, a strategy involving borrowing yen at low interest rates to invest in higher-yielding foreign assets. UBS analysts conclude that the trade remains attractive due to persistent global interest rate differentials, forecasting continued yen weakness and a low probability of a major unwinding.
Imagine you borrow money from a friend who charges very little interest, like Japan's low rates, and then lend it to another friend in a different country who pays you much more interest. You make a profit from the difference! Even though your first friend might start charging a tiny bit more interest, the difference is still big enough that you probably won't stop this money-making game, so the money keeps flowing.
Analysis
UBS Research Report
According to an October 14 report by UBS, concerns regarding the unwinding of yen-funded investments have escalated following a sharp sell-off in Japanese government bonds. However, the bank's rates and foreign exchange strategists have assigned a very low probability to a significant reversal of the yen carry trade. Their analysis suggests that the trade retains its attractiveness, even with the recent rise in Japanese borrowing costs, primarily because the underlying interest rate differentials that make the strategy profitable largely persist across global markets.
UBS maintains a constructive outlook on emerging-market equities, citing robust earnings growth and more reasonable valuations after a sell-off earlier in the year. The bank specifically identified Korea, Brazil, and China as preferred markets, anticipating that improving corporate earnings in these regions could effectively counterbalance any risks stemming from tighter global financial conditions. This perspective underscores a belief in the resilience of these markets despite potential shifts in global capital flows.
Japanese Government Bond Yields
Japanese bond yields have seen a substantial increase, rising approximately 140 basis points over the past two months, reflecting broader pressures observed in government debt markets worldwide. This surge in yields has naturally fueled speculation about the potential for a reversal in the yen carry trade, as higher domestic yields could reduce the incentive for Japanese investors to seek returns abroad. However, the UBS report highlights a crucial counterpoint: global yields have also risen concurrently.
This synchronized increase in yields across major economies means that the fundamental interest rate differentials, which are the bedrock of carry trade strategies, have largely been preserved. Consequently, the relative attractiveness of borrowing in yen to invest in higher-yielding foreign assets remains intact. UBS expects the yen to continue its weak trajectory, with its Japanese macroeconomic team projecting the Bank of Japan's interest rates to peak around 2% within the next 12 months, a forecast that contrasts with broader market expectations for more aggressive tightening.
Emerging Markets
UBS also meticulously examined the potential vulnerabilities of various emerging markets should Japanese investors begin repatriating capital. The United Arab Emirates, Singapore, Australia, South Africa, and India were identified as having relatively high Japanese equity ownership compared to their overall market capitalization. This exposure could render them susceptible to significant shifts in investment flows if the yen carry trade were to unwind or if Japanese investors decided to bring their capital back home.
Historically, equities in Korea and Brazil have demonstrated particular sensitivity to rising Japanese government bond yields, suggesting a precedent for market reactions to such financial shifts. Conversely, South African, Korean, and Thai equities have shown a tendency to outperform during periods of yen appreciation, indicating a varied and uneven impact across different emerging markets. Furthermore, the analysts noted that materials stocks have historically benefited from yen strength, providing a specific sectorial insight into potential market dynamics related to currency movements.
Key points
- UBS research indicates a major reversal of the yen carry trade is highly unlikely.
- Despite a 140 basis point rise in Japanese government bond yields, global interest rate differentials remain attractive for carry trade strategies.
- UBS forecasts the yen to remain weak, with the Bank of Japan's interest rates peaking around 2% within 12 months.
- Emerging markets such as the UAE, Singapore, Australia, South Africa, and India are identified as potentially exposed to capital repatriation due to high Japanese equity ownership.
- Historically, materials stocks have benefited from yen strength, while Korean and Brazilian equities have been sensitive to rising JGB yields.
UBS maintains a constructive outlook on emerging-market equities, citing strong earnings growth and more reasonable valuations, suggesting that the carry trade will continue to support these markets despite global financial conditions.
A significant reversal of the yen carry trade, though unlikely, could force investors to sell foreign assets and repurchase yen, potentially disrupting global markets and exposing emerging economies like the UAE, Singapore, Australia, South Africa, and India to adverse capital flow changes.
