Spanish consumer prices in March 2026 stood at 3.4%, more than a point above February’s, pushed by fuel and energy. It was the highest rate since mid-2024, and it confirmed in the statistics what many households were already noticing at the petrol station and on the electricity bill.
Inflation is a silent tax: it appears on no invoice, but it reduces what each euro can buy. It is worth understanding where it comes from, whom it affects most and what can be done, at home and in the company, without falling into alarmism or indifference. A monthly figure is a snapshot, not a verdict, but it deserves attention when it moves so much. What matters is not the decimal but the trend and how long it lasts.
What drove the figure
Fuel and energy explained a good part of the jump. It is supply-side inflation, originating in the cost of raw materials and not in excess demand, which makes it harder to combat with the usual tools of economic policy, designed above all to cool or warm consumption. Raising interest rates, for example, slows demand, but it does not make a barrel or a kilowatt hour any cheaper.
Moreover, a rise in energy does not stop at the pump or the electricity bill. It makes transport, production and distribution dearer, and can end up reflected in the prices of very different goods. Economists call these second-round effects, and watching them is one of central banks’ concerns when energy rises. If wages and prices begin to chase each other, a temporary rise in energy can turn into a more lasting problem.
Effect on household savings
Inflation was again eroding purchasing power and savings: what costs a hundred today costs more tomorrow. Those who keep cash idle lose real value every month, and families on fixed incomes, such as wages or pensions, feel the cut in purchasing power sooner. Basic expenses, such as energy and food, weigh proportionally more in lower-income households, which also have less room to save.
The point is not to spend or invest in a hurry, but to distinguish between the liquidity needed for day-to-day life and emergencies and the money that can wait. It pays to compare from time to time what savings earn with the pace of prices, and to talk to an adviser about how to preserve the value of what has been saved without taking risks one does not understand. And faced with any product that promises protection against inflation, it is worth asking for a clear explanation of how it works and what it costs.
Margins and contracts in business
For companies, inflation squeezes margins when costs rise faster than selling prices. Companies with price-revision clauses in their contracts could pass costs on; those without had to absorb them. It is a good moment to review the wording of long-term contracts. A contract signed years ago at a closed price may have stopped being profitable without anyone noticing.
It is worth checking which index the clauses refer to, how often they apply and whether they cover the costs that really weigh on the business. It also helps to follow the cost structure closely, to update tariffs regularly and to explain changes to customers in advance and openly. A well-communicated increase is accepted better than a surprise on the invoice. And if the margin narrows structurally, it is worth asking whether the pricing model is still the right one.
Against inflation, the best defence is to know where the costs are and how they are passed on.
