Swiss franc threatens yen's dominance in global carry trade

The Swiss franc is increasingly being utilized as a funding currency in global carry trade strategies, a role traditionally dominated by the Japanese yen. This shift reflects changing dynamics in international financial markets and investor behavior.

Carry trade strategies involve borrowing in a low-interest-rate currency to invest in assets denominated in a higher-yielding currency. For decades, the Japanese yen served as the primary funding currency due to Japan's prolonged period of near-zero interest rates. However, recent market volatility, potential interest rate increases by the Bank of Japan, and significant currency fluctuations have made the yen a riskier choice.

In contrast, the Swiss franc presents an attractive alternative. Switzerland's National Bank maintains a base interest rate of 0%, with limited expectations of immediate significant increases. The central bank also aims to prevent excessive appreciation of the franc, which could harm exports. This environment makes the franc a relatively cheap source of funding for investors.

Data indicates that strategies borrowing in Swiss francs and investing in emerging market currencies have yielded higher returns compared to similar trades funded by the yen. For instance, a trade involving Swiss francs and Mexican pesos reportedly yielded nearly 4% in one month, significantly outperforming a yen-funded trade that returned around 1.3%. This divergence highlights why investors are now exploring alternatives to the Japanese yen for their carry trade operations.
