〔Overnight Brief〕October CPI Beat Fully Prices a December Fed Hike, but 50 bp Probability Split Between 11.5% and 15.3% as the 10-Year Auction Stops at 5.020% — Inflation Meets a 2.46 Bid-to-Cover

0. Overnight Arc

Before the release, U.S. stock futures were mixed and struggling for direction after the market's best day since April ^[1]. October CPI then came in hotter than expected, and 2-5 year Treasury yields rose more than 10 bp ^[2][3][4]. The source base is uneven: the BLS entry is a Google News aggregation rather than a direct link, and several supporting stories are headline-only Google News items, so this packet supports the direction of the surprise more clearly than the exact CPI details ^{[2][3][5][6][7]}. Net overnight arc: markets fully priced a December Fed rate hike while the 2.46 bid-to-cover 10-year auction supplied a countervailing demand signal ^[8][9].

1. Inflation and Policy

• **[ESCALATED] Federal Reserve official Paulson:** called the CPI inflation picture somewhat unsettling, said service-sector inflation had not declined, and put underlying inflation at 2.5%-3.0% ^[10][11].
• **[ESCALATED] Federal Reserve official Paulson:** argued that gradual rate hikes give the economy time to adjust, said CPI still showed inflation as a problem, and supported the Fed's recent rate decision ^[12].
• **[NEW] Fed Governor Bowman:** warned that U.S. stock valuations face the risk of a substantial correction ^[13]. The supplied Federal Reserve page lists a Bowman speech at the Council on Foreign Relations, but the packet contains no substantive excerpt from it ^[14].
• **[ONGOING] Fed Governor Christopher Waller:** supported rate hikes and said he would favor 50 bp if inflation continued to accelerate; traders responded by fully pricing a 25 bp December move ^[15][4].

2. December Pricing

• **[NEW] December pricing after CPI:** CME FedWatch showed a 15.3% probability of 50 bp, up from 0% on the prior day, an 84.7% probability of 25 bp, and a 100% probability of some December hike ^[9][16].
• **[NEW] A separate market snapshot:** showed 11.5% for 50 bp and 88.5% for 25 bp ^[13]. Across the two cited snapshots, the 50 bp band is 11.5%-15.3% and the 25 bp band is 84.7%-88.5% ^[13][9].
• **[NEW] Citi:** closed its December FOMC swap long for a 9 bp gain, also closed a two-year breakeven-inflation short paired with a gasoline-futures hedge, and maintained high confidence in a long 30-year breakeven trade because long-run inflation expectations were viewed as too low ^[15].
• **[ONGOING] Forward path:** traders increased bets on at least two Fed hikes by mid-2027 ^[17][4].

Source-quality note: the 15.3%/84.7% split is an instrument-specific FedWatch snapshot, while the 11.5%/88.5% split comes from a broader market digest without a calculation timestamp; quote the range, not a single point ^[13][9].

3. Bonds, Auctions and Risk Assets

• **[NEW] Treasury selloff:** 2-5 year Treasury yields rose more than 10 bp after CPI ^[4].
• **[NEW] 10-year auction:** the Treasury auctioned $42 billion of 10-year notes with a 5.010% pre-auction yield, stopped at 5.020%, and saw bid-to-cover fall to 2.46 from 2.77 ^[8][18][19]. The auction therefore paired a 1 bp stop premium with a 0.31 decline in bid-to-cover ^[8][18].
• **[NEW] Equities:** at the open, the Nasdaq was down 0.82%, the S&P 500 down 0.66%, and the Dow up 0.48%; Nvidia fell 3.5% and SpaceX more than 3% ^[20]. A broader market digest put Nvidia's two-day loss above 9% and noted multiple large-bank target cuts ^[13].
• **[NEW] Mortgage rates:** the prior month's calm run was broken after the hotter-than-expected CPI; before the break, the worst one-day move in a top-tier 30-year fixed loan was a 0.06% increase and the average day was a 0.02% decline, while the supplied item gives no exact new rate ^[21].

4. Consumer Credit

• **[NEW] Consumer leverage:** the New York Fed's latest household-debt report put credit-card balances up $22 billion in the third quarter to a record $1.29 trillion, up 4.2% y/y ^[22][23].
• Newly issued credit cards carried an average rate of about 24%, while New York Fed researchers said repayment difficulties were most pronounced among low-income and lower-credit-score borrowers ^[23].
• **[ONGOING] Rate baseline:** the effective federal funds rate was 3.88% on Nov. 9, unchanged from Nov. 6, while transaction volume eased to $95 billion from $105 billion ^[24].

Combined with higher yields, the household data adds a consumer-side constraint to the tightening narrative ^[23][24][4].

5. Falsification Test

The working thesis is that markets have repriced the direction of Fed policy with confidence but not the size of a December move ^[13][15][9]. It would be weakened by a reversal in the more-than-10 bp move in 2-5 year yields, a 10-year retracement below the 5.010% pre-auction level after its 5.020% stop, or a material reduction from the current 100% probability of any December hike ^[18][9][4]. It would be strengthened if the auction's lower 2.46 bid-to-cover is followed by renewed pressure in long yields and a 50 bp probability rising above the cited 11.5%-15.3% band ^[13][8][9]. Bottom line: hawkish on direction, contested on magnitude, and mixed on whether bond demand can absorb the repricing ^{[13][8][18][9]}.
