Japanese Yen: Changing fundamentals challenge carry – Rabobank

Senior FX Strategist Jane Foley of Rabobank notes that speculation surrounding a structural shift in Japanese Yen (JPY) valuation is challenging conventional carry trade assumptions and the appetite of Japanese investors for foreign assets. The rising yields of Japanese Government Bonds (JGBs), a resilient economy, and stronger real wages are increasingly bolstering the Yen, especially if the Bank of Japan (BoJ) adopts a more hawkish stance.

Another factor affecting sentiment is the market's speculation regarding a potential fundamental change in the value of the JPY. This has significant consequences for long-held perspectives on the carry trade and the likelihood that domestic Japanese investors may be less motivated to invest in foreign assets, such as US treasuries.

The primary concern revolves around the JPY's role as a funding currency and the potential for a rapid acceleration in the unwinding of JPY shorts near-term. Furthermore, an appreciating JPY would introduce fresh uncertainty about whether domestic Japanese investors would have less incentive to seek opportunities abroad. The increase in JGB yields has already become a focal point, as there have been suspicions for some time that the US Treasury has been concerned about large Japanese insurers potentially selling US government debt for JGBs.

Although there were unconfirmed reports of the Japanese authorities engaging in price checking in USD/JPY last week, the recent surge in the Yen's value seems to have occurred without such intervention. This is more impactful than intervention since it suggests that the market may be reflecting a change in Japanese fundamentals.

Other factors contributing to the Yen's strength include domestically generated inflation driven by real wage data, a robust economy supported by Japanese corporations in the semiconductor supply chain, and stock market reforms. While the Yen may be vulnerable to a tone other than hawkish from the BoJ this month, the medium-term outlook remains positive.
