Rapid disinflation
Updated
What it is
Disinflation refers to a slowdown in the rate of price increases (inflation falling while prices still rise), as distinct from deflation where prices fall outright. A rapid-disinflation scenario is typically invoked as a condition that would give a central bank room to cut interest rates without reigniting demand-driven price pressure. It is normally associated with softer demand, cheaper energy and food, or easing supply-chain bottlenecks.
Why it matters lately
2026 has produced the opposite of rapid disinflation: an Iran-war-driven inflation shock. US producer prices rose 0.4% in August 2026, pushing annual wholesale inflation to about 5.4%, as the Strait of Hormuz disruption pushed Brent crude above $100 a barrel and US gasoline above $4/gallon; consumer inflation had already hit roughly 4.2% year-over-year in May 2026, its highest reading in three years.
Asymmetric Analytics view
Inference (AA): Because 2026's inflation shock is supply-driven (war, energy, food) rather than demand-driven, AA treats the rapid-disinflation scenario as currently falsified and weights scenarios where the Fed stays restrictive for longer.
