Yen Intervention Risk Heats Up, Swiss Franc Becomes New Carry Trade Favorite
Nashnova编辑部
After the joint US-Japan yen intervention, carry-trade funding is shifting from the yen to the Swiss franc — Switzerland's zero-percent rate and lower volatility make the franc a cheaper funding source, a trend that could push it weaker still.
What is a carry trade, and why has the yen suddenly become risky to borrow?
A carry trade means borrowing a low-rate currency and buying higher-yielding assets to pocket the spread. The yen has long been the default funding currency.
The joint US-Japan intervention now keeps markets on guard for further action; add rising Bank of Japan rate-hike expectations and speculation that GPIF — Japan's government pension fund — may shift assets home, and the cost of shorting the yen has jumped.
This means → The old assumption that "borrowing yen costs almost nothing" is broken. Traders need a new low-rate funding currency.
Why is the franc stepping into the yen's role?
The Swiss National Bank's policy rate sits at 0%; Japan's is 1% — franc funding is simply cheaper.
Adarsh Sinha, head of global G10 FX strategy at Bank of America, notes the franc's volatility is also lower than the yen's. Lower rate + lower vol = a more attractive funding currency.
In plain terms = borrowing francs is cheaper and steadier than borrowing yen, so carry traders naturally migrate toward the lower-cost option.
Is the franc already weakening?
EUR/CHF trades around 0.9385, about 4% softer than the near-11-year high of roughly 0.9 hit in March; the franc is down nearly 7% against the dollar from its January high.
Rabobank raised its 9-to-12-month EUR/CHF target from 0.94 to 0.95, pricing in further franc weakness.
Bank of America holds a short CHF/JPY recommendation with a target of ¥190 per franc — the pair currently trades near ¥196, down from about ¥200 before the intervention.
Will the Swiss central bank push back against franc weakness?
Quite the opposite. The franc is still roughly 12% stronger against the euro than five years ago, and that strength squeezes export competitiveness and economic growth.
The SNB has explicitly stated it will intervene in markets to push the franc down if necessary.
This means → If carry trades weaken the franc organically, that aligns with exactly what Swiss policymakers want — no pushback is likely.
How far along is this shift, and what is the key test?
Chris Turner, head of global markets at ING, says the move to the franc as a yen substitute is "still at an early stage."
Fredrik Repton, senior portfolio manager at Neuberger Berman, says "market participants will look to rotate some of their funding positions." He is less bearish on the franc than two months ago but still holds a negative view.
This reflects a single pivot point: whether the yen can hold its post-intervention gains is the core test for how far this carry-currency rotation goes — if the US and Japan succeed in keeping the yen strong, the franc-substitution trend could accelerate.
