Inflation

Inflation measures how fast prices for everyday goods and services rise across the economy. It is the single most important number in macroeconomics because it directly shapes interest rate decisions, consumer behavior, asset prices, and economic growth. When inflation runs hot, the central bank raises interest rates to cool things down. When it falls, rate cuts come into view. Understanding what pushes inflation up and down is the key to reading almost every other economic signal.

Main drivers

What pushes inflation up

• Oil and energy prices — Energy is a direct part of the consumer price basket and an input cost for producers, so rising oil prices flow quickly into higher gasoline costs and overall prices.
• Shelter costs — Rent and homeowner housing costs make up roughly 30% of the monthly price index, so when they stay elevated they keep inflation sticky even if other categories cool.
• Tariffs and trade policy — Taxes on imported goods raise the cost of foreign products, and businesses pass those costs on to consumers with a lag.
• Rising producer costs — When businesses pay more for inputs like natural gas and raw materials, they eventually charge consumers more for finished goods.

What pushes inflation down

• Falling energy prices — Cheaper oil and gasoline pull headline inflation lower almost immediately.
• Falling food prices — Food is a volatile piece of the price basket, and when it moderates, overall inflation drops.
• Higher interest rates (feedback loop) — When the central bank raises rates, borrowing gets more expensive, demand cools, and price pressures ease over time.

Historical examples

When inflation increased

• Oil and energy prices

  • September 2023 oil spike — Oil prices held near their highest levels since November as U.S. crude inventories plummeted by 10.6 million barrels in late August, far exceeding forecasts. This raised fresh concerns about a new wave of inflation.
  • Mid-2025 oil price rise — Oil climbed toward $69 per barrel as Houthi attacks on Red Sea shipping raised supply fears, the EU moved to tighten sanctions on Russian oil, and summer travel boosted demand. Gasoline prices rebounded and helped push annual inflation from 2.4% in May to 2.7% in June 2025.

• Shelter costs

  • January 2025 surprise — Consumer prices rose to 3.0%, above the 2.9% forecast, largely because shelter costs jumped 0.4% in a single month and accounted for nearly 30% of the total increase.
  • April 2023 stickiness — Core inflation ticked up for the first time in six months to 5.6%, boosted by persistent shelter price increases that refused to come down alongside other categories.

• Tariffs and trade policy

  • Late 2024 tariff fears — Federal Reserve meeting minutes from December 2024 revealed that almost all officials saw rising inflation risks from potential changes in trade and immigration policy.
  • June 2025 tariff pass-through — Businesses began passing on higher import costs from tariffs imposed since February, particularly in furniture, toys, recreational goods, and automobiles. Core inflation was projected to edge back up to 3.0%.

• Rising producer costs

  • September 2023 producer price jump — Producer prices rose 0.5% in a single month, well above the 0.3% forecast, driven by a 5.4% surge in gasoline costs. Declining natural gas output and rising exports to Mexico contributed to the supply squeeze.

When inflation decreased

• Falling energy prices

  • March 2025 decline — Annual inflation eased to 2.6%, its lowest since October, driven in part by a decline in energy prices that pulled headline numbers down.

• Falling food prices

  • March 2023 disinflation — Annual inflation slowed for a ninth straight month to 5.2%, the lowest since May 2021, brought down by lower costs for both energy and food.

• Higher interest rates (feedback loop)

  • Early 2023 cooling — After aggressive rate increases by the Federal Reserve, inflation fell to 6% in February 2023 from much higher levels, the lowest reading since September 2021. Officials continued to favor further rate increases to keep the pressure on prices.
  • Mid-2023 rapid disinflation — Inflation fell from 6% in February to around 3% by June 2023 as the combined force of rate hikes, falling energy costs, and moderating food prices all worked together. A banking crisis in March 2023 tightened lending conditions further, adding to the cooling effect.

Who benefits

When inflation rises

• Oil-producing regions and energy sectors — Rising energy prices, a key inflation driver, directly increase revenue for energy producers.
• The U.S. dollar — Higher inflation triggers expectations of higher interest rates, which widens the gap between U.S. and foreign rates and attracts capital, strengthening the dollar. In September 2023 the dollar index held at its strongest level in ten months as a central bank official said there was nearly a 50-50 chance rates would need to move significantly higher.
• Owners of real assets like commodities — Physical goods tend to hold their value or appreciate when the general price level is climbing.

When inflation falls

• Consumers — Falling inflation preserves household purchasing power and lifts confidence. Consumer sentiment surged to 72.6 in July 2023, its highest since September 2021, largely because inflation was slowing.
• Gold — When inflation cools enough to make rate cuts likely, gold rallies because the cost of holding an asset that pays no interest drops. Gold hit a record $2,440 per ounce in May 2024 after signs of slowing consumer prices gave the central bank more room to cut rates.
• Stock markets — Lower inflation means lower expected interest rates, which makes future corporate earnings worth more today. In April 2023, weak retail sales and falling producer prices boosted hopes that the rate-hiking cycle was ending, lifting equities.
• Homebuyers and the housing sector — Lower inflation leads to lower mortgage rates, improving affordability. During 2023, high rates caused mortgage applications to drop 8.8% in a single week and pushed residential investment into contraction for eight straight quarters.
• Manufacturing — Lower borrowing costs stimulate orders and ease margin pressure. Manufacturing had contracted for six consecutive months by April 2023 under the weight of high rates, so any relief from falling inflation directly supports that sector.
• Rate-sensitive growth sectors in stock markets — When long-term bond interest rates topped 4% in March 2023 on hot inflation data, investors fled technology and other high-growth stocks. Falling inflation reverses that dynamic.

The feedback loop

Throughout the entire 2023 to 2025 period, a powerful cycle operated: inflation data shaped central bank rate decisions, rate decisions shaped demand, and demand shaped future inflation. In mid-2023, falling inflation shifted expectations from "rates staying high for a long time" to "rate cuts ahead," which loosened financial conditions and supported risk assets. By mid-2025, converging forces — tariff pass-through, rising oil, and sticky shelter costs — pushed inflation back up, tightening expectations again. This loop is the engine that connects inflation to nearly every corner of the economy.
