The Higher-Altitude Equilibrium: The Federal Reserve's October 2026 Hold, the Neutral-Rate Debate and IS-LM Shift Scenarios to August 2027

On 28 October 2026 the Federal Open Market Committee held the federal funds target range at 3.75–4.00 per cent by a 10–2 vote, with two dissents favouring an immediate hike, one month after the first increase since 2023. This article reads the decision as evidence on whether the United States is settling into a higher-altitude IS-LM equilibrium, in which a higher interest rate coexists with resilient output because AI-related investment has shifted the IS curve right while policy holds the LM curve higher. It documents transmission to equities, Treasuries (a bear steepening with the 10-year yield above 5 per cent), digital assets and private equity; assesses claims of political timing; examines household pressure into the holiday season; and compares the FOMC longer-run rate of 3.2 per cent with model-based and market-implied neutral-rate estimates. Three IS-LM scenarios with timelines to August 2027 are presented as labelled projections with stated assumptions. The article argues that the likely path is a compositional shift toward capital-intensive, high-value production that is distributionally regressive in the near-to-medium term, and traces spillovers to Bangladesh and the Global South through the dollar, external financing costs, imported inflation and capital flows, with implications for reserve management, debt strategy and domestic capability building.
