Japan is flashing a macro signal that matters for crypto.

Nikkei 225 just hit a three-month high around 70,700. Meanwhile their bond market is at a 30-year extreme — 10-year JGB yield at 3.11%, 30-year at 4.22%. Same day, PM Takaichi promised more fiscal expansion.

The BOJ hiked to 1.25% back on September 18. Governor Ueda says hikes are on the table at every meeting, including this month's. Tokyo core inflation just jumped. So the BOJ is tightening while the government is spending.

The yen is sitting near 158 to 160. Japan has already spent a record $96.5 billion defending it. Treasury Secretary Bessent expects Japan to act to lift the yen further. Next BOJ meeting: October 29-30.

Why crypto traders should care: Japan is where cheap money comes from. Higher yields and a firmer yen shrink the carry trade — the trade that funds risk assets worldwide, including $BTC and alts.

Japan's bond market is repricing global liquidity right now. If the yen strengthens and JGB yields keep climbing, that's less fuel for risk-on moves. Watch October 29-30. If the BOJ hikes again or signals more tightening, expect volatility across crypto and equities. This is a liquidity event in slow motion.
