Key takeaways
- Ueda clarified that retained earnings from overseas affiliates stay invested abroad and do not automatically create yen‑selling pressure on Bitcoin.
- A leveraged yen‑carry unwind, not the income surplus itself, would be the more plausible trigger for rapid Bitcoin selling.
- Japan’s recent net purchases of foreign bonds and equities suggest that a simple liquidation of foreign assets is not yet evident.
Bank of Japan Governor Kazuo Ueda delivered a lecture to the International Monetary Fund on November 6, outlining why Japan’s growing overseas profit surplus should not be read as a direct catalyst for a Bitcoin sell‑off, according to a report by CryptoSlate.

Why overseas profits do not equal yen inflows
Ueda explained that earnings generated by Japanese affiliates abroad are often retained and reinvested in those overseas businesses. This accounting treatment expands both Japan’s primary income surplus and its outward foreign‑direct investment (FDI) without requiring the cash to be repatriated. Since 2012, outward FDI has overtaken portfolio investment as the dominant form of capital outflow, meaning that the bulk of foreign earnings remain tied up in foreign assets rather than converting into yen.
Leverage, not income, drives Bitcoin exposure
The lecture distinguished between passive income retention and active leveraged positions such as yen‑carry trades. In a carry trade, investors borrow low‑yielding yen to fund higher‑yielding assets, sometimes using derivatives. A stronger yen or tighter margin requirements can force these leveraged positions to unwind quickly, creating a more immediate selling pressure on Bitcoin. This mechanism aligns with a 2024 Bank for International Settlements study that linked yen‑funded leverage to amplified market turbulence.
Recent data shows no clear liquidation trend
Japan’s Ministry of Finance reported that designated reporting institutions were net buyers of foreign long‑term debt and equity during the week of October 25‑31, contradicting a simple narrative of foreign‑asset sell‑offs. The ministry’s upcoming releases for early November will provide further insight, but the current weekly data suggests that Japanese investors are still allocating to overseas securities rather than converting proceeds into yen.
What to watch next
Analysts will monitor the Ministry of Finance’s November 10 and 12 releases for signs of sustained foreign‑security disposals, as well as any sharp movements in the yen that could stress leveraged carry positions. A sudden spike in margin calls or a rapid yen appreciation would be the most direct catalyst for a Bitcoin price impact, according to Ueda’s assessment.
