Import parity often appears in news and debates whenever fuel prices come up. Despite the technical name, the idea behind it is simple and helps explain purchasing, selling, and supply decisions in the country.

In practice, talking about parity is talking about comparison: how much it costs to bring fuel from abroad versus producing and selling it domestically. Below, the concept is broken down into parts, without complicated terms.

What is import parity, in simple terms

Import parity is a price reference. It answers the question: if Brazil needed to import gasoline or diesel today, how much would it cost until the product arrives here?

This reference value considers the international price of the fuel and adds the costs for it to be available in the Brazilian market. It is not a single or fixed price, but a parameter used for comparison.

What goes into this calculation in practical terms

Without formulas, parity usually reflects a set of objective factors, such as:

- International fuel price - Exchange rate (how much the real is worth against the dollar) - Maritime transportation costs - Port fees and insurance - Domestic logistics to distribution centers

These elements vary over time, which explains why parity also changes.

Why Brazil looks at parity even with local production

Although the country produces oil and has refineries, the Brazilian market is not isolated. At times, domestic production does not cover all demand or does not meet all specifications.

Parity works as an economic signal:

- It indicates whether it makes sense to import to complement supply - It helps avoid product shortages during periods of higher consumption - It serves as a reference for commercial decisions in the sector

Parity is not the pump price — understand the difference

An important point: import parity is not the amount the consumer pays at the gas station.

The final price includes other layers, such as:

- Distribution and retail margins - Federal and state taxes - Mandatory blends of ethanol and biodiesel - Local operating costs

For this reason, even when parity rises or falls, the impact at the pump may differ in intensity and timing.

When parity gains more weight in the debate

Parity tends to draw more attention in some specific scenarios:

- Increases in oil prices on the international market - Rapid exchange rate fluctuations - Periods of greater dependence on imports - Discussions about pricing policy in the oil and gas sector

At these times, the term appears as a way to explain cost pressures perceived along the chain.

How this concept affects daily life, even if you don't notice it

Even if consumers do not closely track parity, it influences decisions that keep the market supplied. When domestic prices move too far away from this parameter, importing can become more or less attractive, which affects supply and logistics.

Understanding import parity helps you read the news more clearly and separate what is a market reference from what actually makes up the price paid day to day.
