The financial market has reacted positively to the information related to US inflation. Inflation is a quantity that indicates the change in the price of goods or services over time. For example, if a bottle of milk costs $1 but increases to $1.10 after a year, the annual rate of inflation for milk is 10%.

The BLS uses this index to calculate total inflation in the United States economy. This index is updated periodically as spending trends and consumption habits change over time. Several factors can cause inflation to increase.

If demand for a product exceeds its availability, producers may increase prices, such as the recent mania for dollar Labubu and high reproduction prices. Other factors may include an increase in income levels, such that it may increase demand and therefore prices. Additionally, if the supply of a product is reduced but the demand remains constant, this can cause prices to rise.

A good example of this is crude oil, used to make gasoline and diesel. Before the Iran-US attack, it was around $70 per barrel, but when the war between the United States and Iran has limited the oil resources, prices have rapidly risen and are currently above $100. In the week leading up to the midterm elections, pressure on prices of goods and services in America was met through inflation.

US inflation exceeded in the last few weeks, with a variation of 0.4% in October. This variation is lower than the one registered in the previous month (0.6%). However, analysts had predicted a variation of 0.3%, and today's higher variation could contribute to arguments for a Fed announcement of tax release at their December meeting.

New figures were released a week after the midterm elections, which took place against the backdrop of daily life pressure in America. Inflation is an important indicator to understand how real costs of goods or services change in real time. For what concerns the US economy, inflation is a problem that must be managed by government entities such as the Federal Reserve.

The Federal Reserve aims to keep annual inflation at 2%. When inflation is too high, the Fed tends to increase taxes to encourage people and businesses to spend less and save more, hoping that this slows down price pressures. Additionally, no information on annualized inflation for October was obtained, but calculations based on available data until September show an annual inflation rate of 3.7%.

The BLS normally provides data on annual changes in inflation, but it has not reached this measure for October 2025. Moreover, while there are no published annual inflation figures for October, analysts think that the importance of higher-than-expected inflation may increase the probability of a Fed announcement of tax release at their December meeting.
