Modest inflation to help consumers maintain spending momentum

RBC expects December core CPI to rise +0.15% month-over-month with year-over-year core CPI holding at +2.6%, helped by a modest owners’ equivalent rent (OER) print; tariff passthrough is expected to become more evident in H1 2026 and the January CPI will use updated 2024 CEX weights that increase housing’s share to 33.4% from 32.9%. The firm also forecasts November retail sales up +0.7% (control group +0.5%), core PPI up +0.3% in October and +0.4% in November, initial jobless claims around 235k for the week ending Jan 10, continued moderation in new home sales, and a -0.1% print for December industrial production with capacity utilization at 75.9%.

Analysis

Market structure: A modest near-term win goes to service-heavy sectors (leisure, healthcare, travel, select REITs linked to housing) as CPI’s larger housing weight and accelerating OER in 2026 mechanically lifts services inflation and pricing power. Losers are import-dependent consumer-goods firms and margin-sensitive retailers as tariff passthrough likely compresses gross margins into H1 2026; expect margins to be most stressed in apparel, consumer electronics and discretionary specialty chains. On cross-assets, a stickier services-driven CPI profile raises the probability Fed delays cuts, pressuring long-duration equities and boosting nominal yields and the USD while supporting TIPS and short-dated real yields.

Risk assessment: Key tail risks are (1) a hot CPI surprise (core m/m >+0.25% or y/y >2.8%) that forces the Fed to keep rates unchanged into mid-2026, triggering a 50–100bp repricing in 2s–10s; (2) an abrupt tariff escalation/shock to supply chains that spikes goods inflation and freight rates; or (3) a faster-than-expected services slowdown if employment softens. Immediate (days): CPI/retail prints; short-term (weeks): PPI backlog and initial claims normalization; long-term (quarters): OER-driven CPI carry in 2026. Hidden dependencies include OER measurement lags and high-income services demand masking broader household weakness.

Trade implications: Favor inflation hedges and quality defensives: establish a 2–3% NAV position in TIPS (TIP) and incremental 1–2% in 2–5yr inflation breakevens if CPI surprises to the upside. Long low-cost retailers/discount operators (WMT, COST) vs short import-dependent apparel (PVH, ROST) as a pair trade to capture margin dispersion; consider 6–12 month horizons. Use options around CPI: buy 1–2 month FDX/UPS call spreads to express freight pricing pass-through on a +0.3–0.4% PPI beat, and buy SPX 1-month 5% put spreads sized as portfolio tail-hedges if core CPI >+0.25%.

Contrarian angles: The market underestimates the mechanical inflation lift from the CEX reweight toward housing — even flat OER prints could raise measured CPI through 2026 by ~0.05–0.10pp y/y, delaying rate cuts and keeping real yields higher. Conversely, if retail sales control falls below +0.2% m/m and initial claims normalize downward, disinflation could be underpriced and long-duration tech/consumer discretionary could materially outperform. Unintended consequence: retailers pre-emptively preserving share may hide margin erosion until H1 2026, creating a late recognition shock in earnings seasons.

Key Decisions for Investors

• Establish a 2–3% NAV long position in iShares TIPS ETF (TIP) over the next 5 trading days; if core CPI m/m >+0.2% or 5y breakevens rise >20bp intra-week, add another 1% allocation.
• Implement a 6–12 month pair trade: long Walmart (WMT) 1.5–2% NAV and/or Costco (COST) 1% NAV vs short PVH (PVH) 1–1.5% NAV targeting margin compression from tariff passthrough; trim shorts if PVH trades down 15% from entry.
• Buy 1–2 month call spreads on FDX (e.g., buy 1 B/E strike, sell 2 B/E strike) sized 0.5–1% NAV to capture freight-rate pass-through if Oct/Nov PPI prints core PPI +0.3–0.4% m/m; delta-hedge post-release.
• Reduce exposure to import-heavy discretionary names (cut exposure by 30–50% over 1 month to tickers like ROST, ANF) ahead of H1 2026 tariff passthrough; redeploy proceeds into staples (WMT/COST) and cash/T-bills if CPI core y/y >2.7%.
• Monitor these triggers over the next 7–30 days and act: core CPI m/m >+0.20% (add duration short/inflation trades), retail control <+0.2% (pause inflation buys and rotate to long-duration growth), and 4-week rolling initial claims >260k (raise equity hedges).
