Middle-income squeeze
Middle‑income households spend a materially larger share of their budgets on necessities like gasoline and groceries than upper‑income households, so higher oil prices hit them harder. RBC's estimate that the bottom 60% spend close to 4% of income on gasoline versus about 2% for the top decile captures this gap and explains why middle‑income sentiment is more fragile even as affluent spending holds up.[3]
Rising gas and food costs have already eroded purchasing power for middle‑income families since 2022, forcing more use of credit and leaving less room for savings or discretionary spending.[2][6]
Oil, CPI, and sentiment
RBC's scenario that year‑end headline CPI lands near 3% with oil around $75 and closer to 3.5% if crude stays above $90 illustrates how an oil shock can stall further disinflation. Higher gasoline and transport costs also bleed into goods and grocery prices, amplifying the impact on households that already devote a large share of spending to essentials.[1][3]
That combination tends to darken consumer sentiment even if the labor market is still OK, because people feel recurring pain at the pump and at the supermarket. Surveys and budget indexes are already showing that many households report high prices as a significant burden and are cutting back or trading down.[1][2]
Implications for the Fed
With headline inflation stuck closer to 3–3.5% instead of gliding to 2%, the Fed is more likely to stay in "wait and see" mode, delaying or reducing rate cuts. Oil‑driven inflation is tricky: the Fed can't pump more oil, but it worries that repeated energy shocks will unanchor inflation expectations and spill over into wages and broader prices.[3][1]
So as long as oil remains high and upper‑income demand keeps overall spending numbers looking decent, the Fed has little urgency to ease policy, even though the middle of the distribution feels increasingly squeezed.[6][3]
