- Bank of Japan meets July 31 with a 99% probability of holding rates at 1%, but future hikes loom as inflation nears 2%.

- Traders brace for volatility as yen weakness and policy uncertainty collide, threatening risk assets across the board.
What Happened
The Japanese yen is crumbling to fresh 40-year lows against the dollar, with USD/JPY flirting with 164 just days before the Bank of Japan’s July 31 rate decision. This slump revives the specter of a carry trade unwind, the same force that sent shockwaves through crypto markets in August 2024. Back then, a sudden yen surge forced leveraged traders to dump risk assets, crushing Bitcoin and altcoin prices. With the BoJ expected to hold rates at 1% but signal future hikes, markets are on edge for a repeat liquidity squeeze.
The Numbers
USD/JPY is knocking on 164, a level unseen in four decades, after briefly dipping post-June’s rate hike. BoJ’s benchmark sits at 1.0%, the highest since 1995, yet still ultra-accommodative by global standards. Polymarket odds show a 99% certainty of no change this week, but the central bank’s own commentary warns that “underlying CPI inflation has been approaching 2%” and rates remain historically low. The yen’s persistent weakness amplifies the unwind risk, as a sudden spike could force traders to cover short yen positions en masse.
Why It Happened
Japan’s decades of near-zero rates turned the yen into the world’s top funding currency. Traders borrowed cheap yen to buy higher-yielding assets globally, including crypto. Now, inflation running close to 2% and a crashing yen are pushing the BoJ toward normalizing policy—even if slowly. Each rate hike or hawkish hint strengthens the yen, forcing carry traders to exit positions rapidly. The August 2024 unwind occurred when the BoJ’s surprise move caught markets off guard. Today’s setup, with the yen even weaker, makes a similar event almost inevitable if policymakers shift tone.
Broader Impact
A carry trade unwind drains liquidity from risk assets. Crypto, heavily correlated with global liquidity cycles, gets hit early and hard. In August 2024, Bitcoin dropped double digits in a single day as yen-funded leverage evaporated. Now, with altcoins already fragile and BTC sensitive to macro shocks, a renewed unwind could spark a broad sell-off. The Yen’s descent also pressures other Asian currencies, adding cross-market tension.
What to Watch Next
- BoJ statement on July 31 for any language suggesting a future rate hike path—hawkish signals could instantly lift the yen.
- USD/JPY price action: A break above 164 or a sharp reversal below 160 will indicate unwind risk intensifying or fading.
- Crypto funding rates and open interest: Spikes in leveraged longs may precede a capitulation if yen volatility erupts.
