US inflation rises to 3.7% as fuel costs climb ahead of midterms

When the CPI says US inflation was 3.7% in September, prices overall were 3.7% higher than September last year. It measures a typical household basket, so individual prices rose by different amounts. It does not mean every item became 3.7% costlier.

Petrol shows how the number can change quickly: prices jumped about 9% from August to September. Fuel also raises transport costs, helping push airfares about 23% higher than a year earlier. Businesses may pass these extra costs to customers.

In September, consumer prices increased 0.6% from August, up from 0.4% in August. Core inflation, excluding food and energy, reached 2.6% annually, suggesting wider price pressure. The figure exceeded economists’ 3.6% forecast and remained above the Federal Reserve’s 2% target. That can keep borrowing costs high as the Fed considers further rate rises.

The report measures how much US prices changed over one month and one year. Overall consumer prices rose 3.7% from September a year earlier and 0.6% from August. Core prices, excluding food and energy, rose 2.6% annually and 0.3% monthly. These figures show inflation spreading beyond fuel.

Petrol was the biggest immediate driver: prices jumped about 9% between August and September. Airfares were about 23% higher than a year earlier, showing how fuel costs can raise travel prices. More expensive petrol also increases companies’ shipping bills, and businesses may pass those costs to shoppers. PepsiCo, for example, planned higher prices for some snacks and drinks.

Inflation accelerated from 3.4% in August, while the 3.7% annual result exceeded economists’ 3.6% forecast. Petrol had eased recently, but averaged $4.34 per gallon on Tuesday, still higher than a month earlier. Persistent core inflation could keep pressure on households and encourage the Federal Reserve to consider another rate increase.

Annual inflation rose because several major household costs increased sharply, especially petrol. The index tracks average price changes. Energy increases can lift the overall rate and spread through businesses.

Petrol prices jumped about 9% between August and September. That raised driving costs directly and increased shipping expenses, while airfares climbed about 23% from a year earlier. Clothing also became more expensive, and businesses can pass higher fuel costs to shoppers.

The result was 3.7% annual inflation in September, above August’s 3.4% and economists’ 3.6% forecast. Core inflation, excluding food and energy, also increased from 2.4% to 2.6%. This suggested price pressures were broadening, increasing pressure on households and the Federal Reserve. The Fed was considering another rate increase at its October 27–28 meeting, though higher rates cannot fix war-related supply disruptions.

Petrol is a basic cost for moving people and products. When it rises, airlines, delivery companies, shops, and manufacturers often pay more to operate. They may pass those costs to customers through higher fares and prices.

Airlines burn fuel on every flight, so pricier petrol raises operating costs and can lift airfares. The article says airfares were about 23% higher than a year earlier. Shipping companies also use fuel to move goods, making food, drinks, clothing, and electronics more expensive. PepsiCo said it would raise some snack and soft-drink prices, citing higher fuel, aluminium, and ingredient costs.

Petrol prices jumped about 9% between August and September, driving much of September’s inflation increase. Businesses may absorb some costs, but persistent increases can spread through supply chains and squeeze household budgets. Prices recently eased, yet averaged $4.34 a gallon on Tuesday, still above a month earlier.

The Fed might raise rates because inflation reached 3.7% in September, well above its 2% target. Rates make mortgages, credit cards, and business loans more expensive, encouraging people and companies to borrow and spend less. Cooling demand gives sellers less room to keep raising prices, helping inflation move downward.

Petrol prices rose about 9% from August to September, and airfares were about 23% higher than a year earlier. Rate increases cannot produce more petrol, but they can limit the wider price effects of costlier fuel. For example, PepsiCo said it would raise some prices after fuel and other input costs increased.

September’s monthly inflation was 0.6%, while core inflation rose 2.6% annually, showing pressure beyond energy. After the report, traders increased bets on another increase, sending the two-year Treasury yield to 4.93%. The Fed’s next meeting is October 27–28, and higher rates may restrain prices, but risk slowing growth.

Interest rates can cool inflation by reducing demand, but they cannot create missing fuel or repair disrupted supply. Higher monthly loan payments discourage borrowing and spending, giving businesses less power to raise prices.

After the Iran war pushed petrol prices higher, US petrol prices jumped about 9% from August to September. Raising rates cannot produce extra oil or reopen disrupted transport routes. It can only limit secondary effects, such as consumers spending less elsewhere and companies passing fuel costs forward.

That distinction explains why the Federal Reserve faced a difficult choice. September inflation reached 3.7% annually, while airfares rose about 23% from a year earlier. The Fed could raise rates to stop energy costs spreading, but tighter credit also slows growth and hurts households. Supply problems require improved production or transport, while rate rises mainly restrain demand.
