〔Overnight Brief〕PBOC's 700B Yuan 6-Month Reverse Repo Pushes 30Y CGB to 2.056% Near Historic Lows, While US Hot CPI Reignites Three Fed Hikes Through 2027 — Domestic Easing vs External Pressure

0. Overnight Arc

PBOC's 700B yuan 6-month reverse repo for Oct 15 ^[1] cemented a domestic easing narrative, pulling 10Y/30Y CGB yields to 1.64%/2.056% — the 30Y within striking distance of historic lows and the 30Y futures main contract posting a fresh YTD high at 118.03 (+0.19% on the day) ^[2]. Yet the same session carried a US Sept CPI above expectations, pushing traders to add Fed October hike bets and price three more hikes through end-2027 ^[1], reopening the RMB question ^[3]. The bond rally is now testing whether the easing trade can hold against an external crosswind.

5. What Would Falsify the Easing Trade

• The 30Y sub-2.1% rally rests on continued asset scarcity and Q4 easing expectations ^[2] — but subway approvals thawing ^[7], 200B yuan of grain-purchase credit ^[13], and the ongoing financial-SOE recapitalisation ^[11] are liquidity-absorbing rather than liquidity-adding.
• US hot CPI is currently news-roundup trader positioning ^[1]; confirmation in core services or wages would pressure the RMB ^[3] and cross-border pricing, undermining the bond rally's external calm.
• Falsifiable test: another 700B+ reverse repo or an RRR cut would deepen the rally ^[1][2]; a confirmed Fed October hike plus a PBOC pause would invert the trade and pull the 30Y yield back toward 2.1%+ ^[1][2].
