Cross-border yen borrowing proxies
Updated
What it is
This indicator uses proxies for the stock of outstanding cross-border yen-denominated borrowing, which approximates how much yen carry-trade funding exists in the global financial system. The main public data source is the Bank for International Settlements' locational and consolidated banking statistics, which report banks' yen-denominated cross-border claims and loans to non-bank borrowers outside Japan. A large and growing stock signals more capital potentially exposed to a yen-funding squeeze if Japanese rates rise or yen volatility spikes.
Why it matters lately
Analysis by Jefferies strategist Shrikant Kale found outstanding cross-border yen borrowing rose about 67% to roughly JPY360 trillion (about $2.3 trillion) between December 2021 and March 2026. Separately, BIS data show banks' yen-denominated claims on non-banks outside Japan reached about $880 billion (JPY133 trillion) by early 2024, up from JPY110 trillion at the end of 2021, with yen loans to non-bank borrowers outside Japan rising from $228 billion to $271 billion over a similar period. Commentators have described this buildup as the largest in three decades, underscoring vulnerability to a disorderly unwind as the Bank of Japan tightened through 2026.
