U.S. disinflation has emerged; the Fed may wait patiently, but durability remains subject to oil-price and demand risks

Overview

The report focuses on the U.S. disinflation process and its implications for monetary policy. Morgan Stanley believes that recent CPI and PPI data support the disinflation view, driven primarily by tariff price pass-through nearing completion, easing energy-price pressures, further slowing in housing inflation, and factors including residual seasonality and PCE statistical adjustments.

Core views

The core view is that the Fed can remain patient conditionally: with inflation softening, employment and wage growth cooling, and limited risk of labor-market overheating, the Fed can leave the policy rate unchanged through end-2026 and allow disinflation to evolve on its own. The report expects cumulative rate cuts of 50 basis points in 2027, but emphasizes that risks are skewed toward a higher rate path.

Analysis framework

The report combines CPI, PPI, and PCE nowcasts, decomposes drivers of core goods, energy, and housing inflation, and uses a financial conditions indicator based on the FRB/US model to assess the federal funds rate-equivalent effect of asset-price changes on economic activity. It also tests the effects of oil prices, demand, and AI investment on growth, employment, and inflation through baseline and alternative scenarios.

Methodology notes

• Macroeconomic ForecastingCPI/PPI-to-PCE Tracking

  Inflation Indicator Mapping

  Uses released CPI and PPI data to estimate monthly headline and core PCE inflation, and compares divergences between CPI and PCE arising from differences in housing weights.

• Financial ConditionsFRB/US Financial Conditions Indicator

  Policy Rate-Equivalent Change

  Aggregates the growth elasticities, estimated using the FRB/US model, of the 10-year Treasury yield, S&P 500 returns, BBB credit spreads, dollar valuation, and oil prices, converting them into a basis-point change in the federal funds rate with a similar effect on economic activity.

• Scenario AnalysisU.S. Economic Baseline and Alternative Scenarios

  Risk Scenario Stress Testing

  Compares growth, employment, inflation, and policy paths under scenarios including stronger demand, AI-driven productivity gains alongside job displacement, a moderate rise in oil prices, a permanent oil-price premium, and an oil-price-driven recession.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• U.S. Treasuries

  Disinflation and holding steady this year reduce expectations for further rate hikes, broadly easing upward pressure on yields.

  Strengths

  Core and headline inflation have recently slowed, while the labor market and wage growth have softened.

  Weaknesses

  PCE remains above CPI, and core PCE is expected to decline only gradually.

  Comparison

  Relative to short-duration assets, longer-duration assets are more sensitive to future disinflation and expectations for 2027 rate cuts.

  Risks

  An oil-price shock, renewed tariff pass-through, or excessively strong demand could all push yields higher.

• U.S. Equities

  Financial conditions have eased since the July FOMC, with rising equities one of the main drivers.

  Strengths

  Moderate disinflation and stable growth support valuations and risk appetite.

  Weaknesses

  Rates will not decline this year, while AI demand may simultaneously raise costs and inflation.

  Comparison

  Sectors benefiting from resilient growth may outperform sectors more sensitive to high rates and with fragile earnings.

  Risks

  A resurgence in inflation could raise real rates, or escalating geopolitical conflict could weigh on risk appetite.

• Crude Oil

  Renewed escalation in the Middle East has lifted spot and futures oil prices, again creating an inflation risk.

  Strengths

  Lower inventories, low Strategic Petroleum Reserve levels, and geopolitical risks all support prices.

  Weaknesses

  The report's baseline scenario assumes no escalation in the conflict, with WTI remaining around $80/barrel.

  Comparison

  An oil-price shock has a greater effect on headline inflation than a direct effect on core inflation, absent second-round effects.

  Risks

  De-escalation of conflict, demand destruction, or a recovery in supply could cause oil prices to decline.

• U.S. Dollar

  Dollar depreciation has been an important source of financial conditions easing since the July FOMC.

  Strengths

  A weaker dollar helps ease financial conditions.

  Weaknesses

  The reversal of dollar weakness since the Middle East conflict began has been one of the main factors tightening financial conditions.

  Comparison

  The dollar's trajectory and the 10-year Treasury yield jointly dominate recent changes in financial conditions.

  Risks

  Rising safe-haven demand or a continued increase in Treasury yields could strengthen the dollar and tighten financial conditions.

Impact & implications

If disinflation continues under the baseline scenario, market pricing pressure for further rate increases should ease, benefiting duration assets and risk appetite. However, the report does not view rate cuts as imminent; holding steady this year remains the main theme. A rebound in oil prices, escalation of geopolitical conflict, or AI-related demand lifting goods and software prices could stall disinflation, weakening expectations for 2027 rate cuts and potentially even creating rate-hike risk.

Risks

• An escalation of the Middle East conflict could push oil prices higher and generate stronger inflation pressure through energy and transportation costs.
• Tariff pass-through may not end fully as expected, or the effective tariff rate approaching 10% by year-end could create new price pressures.
• Sustained strength in AI-related demand for electronics, memory, and software could directly or indirectly raise core goods and services prices.
• Inflation may decline only temporarily, causing expectations for 2027 rate cuts to be withdrawn; in an extreme case, rate hikes of 50–75 basis points may be needed.
• Housing inflation may converge to market rents more slowly than expected.
• Tighter financial conditions, higher 10-year Treasury yields, and a stronger dollar could restrain economic activity.

What to watch

• Subsequent core PCE, core goods prices, and housing-rent-related indicators to confirm whether disinflation continues.
• Oil prices, U.S.-Iran relations, and changes in the Middle East conflict, with attention to potential energy second-round effects.
• Effective tariff rates, tariff revenue, and rebate data to assess whether tariff price pass-through has been completed.
• Discussion in FOMC minutes regarding inflation risks, the degree of data dependence, and the threshold for keeping rates unchanged.
• Signals from employment, wages, industrial production, housing starts, and permits for the growth-inflation mix.
• The combined effects of the S&P 500, the dollar, BBB credit spreads, and the 10-year Treasury yield on financial conditions.
