Bank of Japan Raises Rates to 1%, Unwinding Decade of Yen Carry Trades

Japan’s central bank is almost certain to raise its benchmark rate to 1% at its June 15-16 meeting, a level unseen since 1995, and the 93% market probability has been baked in for weeks. The more consequential question is what the Bank of Japan signals about what comes after.

The rate path matters for crypto in a specific, structural way. Japan’s decade of near-zero borrowing costs made it one of the most hospitable environments in the world for yen-funded carry trades, where investors borrowed cheap yen to buy higher-yielding assets, including digital ones. According to CoinGecko, bitFlyer alone handled nearly 38% of all crypto transactions in Japan, which gives a sense of how concentrated and institutionally legible that market actually is. BTC/JPY remains one of the most active fiat-crypto pairs globally, so when Japan’s cost of capital rises, the knock-on effect on speculative positioning is real, not theoretical. The clearest precedent came in August 2024, when a surprise BOJ rate hike triggered a rapid yen strengthening and contributed to a broad deleveraging across risk assets, with Bitcoin dropping sharply before recovering.

The leadership situation adds a layer of genuine uncertainty that markets have largely ignored. BOJ Governor Kazuo Ueda has been hospitalized with a liver infection and will miss the policy meeting entirely, leaving Deputy Governor Ryozo Himino to chair it, while Deputy Governor Shinichi Uchida, himself recently diagnosed with leukemia, will handle the post-meeting press conference.

With 66 of 70 economists surveyed by Reuters expecting 1% by end of June, and Polymarket sitting at 98% as of June 11, the hike itself is noise. What isn’t noise is the forward guidance, or the likely absence of it. Nomura’s Mari Iwashita told Reuters the BOJ may deliberately avoid signaling its next move given Ueda’s uncertain recovery timeline, which means traders looking for a clear tightening trajectory will probably leave the meeting without one. A hawkish Fed under Kevin Warsh widening the rate differential between Washington and Tokyo only complicates the calculus further, since the yen has already weakened past 160 per dollar, prompting an estimated 73 billion dollars in currency intervention since late April.

The June 16 statement and Uchida’s press conference will tell regulated exchanges like bitFlyer and Coincheck more about their operating environment over the next six months than the rate decision itself. If the BOJ goes quiet on future hikes, yen-denominated trading volumes may stabilize. If it signals another move before year-end, the carry trade unwind that rattled crypto in 2024 has a plausible sequel.
