What Is Inflation and How Is It Measured?
Inflation is a big driving force in economics, often mistakenly considered to be uncontrollable, but it is, in fact, an economic tool used to cool down an overheating economy, often done by central banks raising interest rates. There are, however, many instances where inflation can be spurred on by external factors to centralized processes, like wars or the 2020 pandemic, which had countries divert billions to emergency services and citizen support programs. The pressure put on by the 2020 Covid pandemic, the closing of borders and many businesses for years at a time, had a slow, but very heavy effect on the economy, resulting in an ever-increasing inflation rate.
Inflation can be measured in several ways, by using CPIs, PPIs, PCEs, and core inflation markers, which exclude food and energy prices since these categories are considered highly volatile, as they are affected by changing factors like weather, geographic tensions between countries, and supply chain disruptions.
CPIs, or Consumer Price Indexes, are the most often used way of measuring inflation as it tracks the average change over time of the cost of consumer goods as felt by the consumer. This index follows the price of:
Foods and beverages;
Services;
Housing and rent;
Transportation costs, which include fuel;
Medical care;
Education costs;
Recreational activities.
PPIs, or Producer Price Indexes, measure the price change and the increase in the cost of producing a given unit of goods, let's say bread. PPIs include:
Raw materials needed for manufacturing, including crude oil;
Intermediate goods that are close to being a final product;
Finished products that are sold wholesale to retailers, but not directly to consumers.
A big part of PPIs is also the cost of fuel and crude oil prices since all manufacturing processes require, at least at some stage, transportation, which ultimately increases the cost of production.
PCEs, or Personal Consumer Expenditures, are the preferred inflation-measuring index by economic institutions like the central bank; in the case of the U.S., it's the Federal Reserve. This data set uses a broader range of data to measure inflation, actively adjusts when changes in consumer behavior are a big enough factor, and emphasizes different spending categories. Fuel costs still play a very big role in PCEs, though their impact may be less noticeable than with CPIs.
The long-term trends of inflation are studied by Core Inflation, which generally works better for prolonged periods, as it avoids the data noise created by trends and momentary economic downturns.
Key Inflation Trends in 2025- 2026 in the US
The period between 2025 and 2026 can be described as relatively moderate compared to the past 3 years; however, due to persistently rising inflation, the average household has lost more buying power than in 2022 or 2023. That has left many with the feeling that things are worse and that there is a significant constraint on their ability to live comfortably. There are some notable inflation trends in 2025 - 2026, like:

Stabilizing but not normal - while inflation rates have slowed down, they are still a lot higher than the period before the 2020 Pandemic.
Inflation in certain sectors. The cost of housing, insurance, and healthcare continues to rise steadily despite slowing inflation rates.
Volatile energy prices: One of the backbones of the economy and a requirement for economic growth and sovereignty is a countryβs ability to use energy resources, such as nuclear power, hydro power, coal power, and green or renewable sources. Inflation has also affected energy prices, which affect every aspect of life, production, and economic capabilities.
Different monetary policies: The Federal Reserve has implemented monetary policies that have slowed inflation; however, the line is being pushed by supply-side pressures that still affect consumer prices.
Does Inflation Remain a Global Concern in 2026?
The Biggest Causes of Inflation in 2026
Inflation is one of the biggest global concerns despite its variability across different regions. This can be felt particularly in North American and some European economies that are still developing or coping with restrictions elsewhere in their economies. In these types of economies, prices stay high compared to pre-pandemic levels. Emerging markets also face higher inflation volatility, driven mainly by currency fluctuations, a higher dependence on imports, and a less stable monetary framework. There are several driving factors of inflation in 2026 that show the biggest impact:
- Geopolitical uncertainty and instability cause a disruption in supply chains and energy flows.
- Energy market volatility, which has especially affected oil and gas prices.
- Labor market imbalance, which is leading to rising wages and service costs.
- Trade disruptions and fragmentation as more and more countries shift towards local and regional supply chains.
Due to these factors, inflation is no longer seen as a short-term problem, but a structural challenge that requires constant management by governments and central banks all across the world.
What Drives Fuel Costs Today?
The fuel costs of today are shaped by several major factors, such as the global political climate, political decisions, logistical bottlenecks, and setbacks. Unlike other commodities, fuel prices are heavily affected by both micro and macro-level events, which can cause both short and long-term disruptions that require time to settle.

How Fuel Costs Affect Key Industries
Modern world economies are heavily dependent on fuel consumption, a readily available supply of various kinds of fuels, and therefore will be heavily affected by the increase in fuel costs, such as the case after March 2026, since the start of the conflict with Iran.

Impact on Logistics and Supply Chain Costs
Logistics operations are entirely dependent on the cost of fuel as both rail and road-based freight transportation require diesel to move a large amount of goods, both for consumers and manufacturing. Since the start of March 2026, logistics costs have increased by 20 to 30%, depending on the state, which has put tremendous pressure on logistics companies. This has caused them to increase their prices, and in some cases, to consolidate their efforts. This, on one hand, has caused a supply chain disruption due to a lesser availability, and has further pushed an increase in prices due to a lack of availability.
Fuel Prices and the Auto Transport Industry
Another big participant in the transport industry, the auto transport trade, has reported a big increase in demand, and a lack of availability in many cases, caused by a consolidation in the market. A lot of owner-operators have closed their operations as profit margins melt with the increase in fuel and labor costs. This trend is further exacerbated by the increase in inflation, which has made many small auto transport companies restructure or entirely stop their operations. Just like with the logistics industry, more than 60% of the cost of operations comes from fuel costs, and even a 10% in that regard means a greater reduction in profitability.
Effects on Food Prices and Agriculture
One huge aspect of fuel costs increasing in 2026 is the effect it has had on the agricultural sector. Despite the tax rebates and lower fuel costs for agricultural purposes, farmers from all across the country have reported a greater increase in their expenses related to equipment maintenance and parts availability. This is another big side effect of the supply chain pressure felt across the U.S. As such, the agricultural sector has had to adjust to the changing fuel rates and has had to increase the price of its output. According to international data from the World Bank, FAO, and Eurostat, fuel and energy costs represent up to 40% of the total cost of agricultural production. Modern agriculture is highly mechanized, in some instances even automated, and therefore it is highly affected by fuel and energy costs. According to Eurostat, another 30% of the cost increase in food comes from transportation costs alone. Fertilizer production is also affected by energy costs, as the primary fertilizer type, nitrogen, is very natural gas-intensive and requires a big input to produce a smaller %, meaning it is both expensive and quite demanding on energy sources.
Airline and Travel Industry Cost Increases
Air travel is also affected by cost increases, as more than 30% of the cost of operations comes from refueling. With higher oil prices (higher than $100 a barrel), air travel costs can increase by nearly 30% to compensate for the added cost of maintaining the current available fleet. After labor, jet fuel is the second largest expense for an airline, and with inflation, labor costs also skyrocket. A recent 2026 projection shows that a sharp increase in fuel prices can increase jet fuel costs by an estimated $14 billion in a single year. Some carriers also report an additional $4 to $5 billion in fuel expense increase per carrier. Jet fuel prices have also exceeded $200 per barrel, with some forecasts predicting prices could reach $300 per barrel in extreme cases.
Manufacturing and Production Cost Pressures
Crisis or not, manufacturing and production must continue as costs increase from several aspects. This puts added pressure on manufacturers to maintain their current production levels while keeping product costs relatively accessible to consumers, risking revenue growth. This hides a potential risk of production output reduction, and in some cases, a delay in production, which will additionally put pressure on the supply chain. A good example of this is the lack of availability in microchips, which directly affects several industries, like the auto manufacturing sector, computer parts sector, and basically any industry where computerized equipment is required.

How Businesses Adapt to Rising Fuel Costs
Of course, businesses have to adapt to the developing situation, and some industries have a surprising level of ingenuity to circumvent the growing fuel costs, in order to not only stay afloat, but also grow during a time where other sectors are shrinking or at risk of great losses.
