Japan raises interest rates, which is a very critical market node. Regarding the news “Bank of Japan (BoJ) to raise interest rates by 25 basis points in December, probability 98%,” let’s digest this piece of news:

One sentence conclusion:
This is “bearish” for risk assets (Bitcoin, US stocks), and “bullish” for the Japanese Yen.
Although the act of rate hike itself has been highly priced in by the market (Priced-in), the **“chain reaction” (liquidity shock)** triggered by the rate hike has not been fully digested.
1. In-depth analysis: Bearish or bullish?
For risk assets (cryptocurrencies / US stocks): Structural bearish
* Rising cost of funds: Japan has always been the “blood bank” of the global financial markets (providing cheap funds). A rate hike means the blood bank’s door is closing slightly. Historical data shows that during the three previous BoJ rate hikes (March 2024, July 2024, January 2025), Bitcoin declined an average of 20%-30% in the following weeks.
* Yen carry trade unwind: This is the biggest hidden risk. When the cost of borrowing in Yen increases (from 0.5% to 0.75%), speculators are forced to sell their high-risk assets (BTC, tech stocks) to repay Yen-denominated debt.
For the Japanese Yen (JPY): Bullish
* Narrowing interest rate differential: The US is cutting rates while Japan is raising rates. This “converging” policy will attract capital back to Japan, pushing up the Yen and depressing USD/JPY exchange rate.
2. Has it already been “priced-in”?
This is a layered answer:
First layer: The rate hike “event” — 98% already priced in ✅
* The market (including swap markets and prediction platforms like Polymarket) has indeed priced in a 98% probability of a 25 basis point hike (raising rates from 0.50% to 0.75%).
* This means: If only a “25 basis point hike” is announced on Friday, the market will not be surprised by this news itself, and there might even be a brief “sell the news” rebound.
Second layer: The “consequences” of the rate hike — not yet priced in ❌
* Liquidity shock not priced: Currently, the market generally has a “complacency” sentiment, believing that since everyone knows about it, the market won’t fall. But analysts warn that the market underestimates the chain reaction of Yen carry trade unwinding.
* “Black swan” risk: If BoJ Governor Ueda Shintaro appears extremely hawkish in the press conference (e.g., hinting at rapid rate hikes in 2026), or if the rate hike exceeds expectations (though very unlikely, there are rumors of a 75bps possibility, which is more interpreted as raising rates to 0.75% rather than a 75bps hike), this noise itself indicates potential panic in the market.
3. Actionable insights
* Don’t bet on Friday’s data: Since it’s a 98% certainty, there’s no point in gambling. The real risk lies in the post-announcement statement and the US market reaction.
* Beware of “sell the fact”: For Bitcoin and Ethereum, if the rate hike is announced on Friday and prices do not fall sharply but instead rise slightly, don’t rush to buy the dip. This is often a trap for a false rally, and in the following days, liquidity contraction may trigger a downward trend.
* Watch key levels:
* USD/JPY: If it effectively breaks below 140, it indicates carry trade unwinding is out of control, and risk assets will plummet.
* BTC: The $70,000 level below is the psychological defense line for this rate hike shock.
Summary: The market is already prepared for the “rate hike” headline but not yet ready to adapt to the “world’s cheapest funds disappearing entirely.” This remains a primarily defensive moment.
