20minutos on 22 August 2026 took the trend of “retos de no comprar nada” in Spain as an opportunity to discuss the benefits and limits of no-spend exercises. According to the report, No-buy challenges are booming on social media as an easy way to start saving, but they fall short unless combined with a systematic analysis of large, ongoing expenses.
The principle is simple: for a set period – for example, a month – non-essential purchases are put on hold. The aim is to identify impulse buying, reconsider subscriptions and break routines. This can work as a short-term prompt for behavioural change: clear rules, a fixed end date and a specific focus encourage discipline and awareness. This is highlighted in 20minutos’s coverage and in relevant advice columns, which have been following the trend for some time.
The limits become clear when structural costs are left out of the picture. According to the official household budget survey, Encuesta de Presupuestos Familiares of the INE the gasto medio por hogar in Spain in 2024. The largest category is housing, including energy – in the INE classification, “Vivienda, agua, electricidad, gas y otros combustibles”. The finding: a substantial part of the budget is already committed to rent or mortgage payments, insurance, energy contracts and mobility. Those who do not review opportunities to optimise these costs may save here and there through purchase bans alone, but will only shift their monthly spending range to a limited extent.
Three sober points can be drawn from the current assessment. First: no-buy challenges are useful as a time-limited learning tool for making automatic purchasing patterns visible and identifying triggers. Second: a lasting effect only comes when major, sometimes negotiable expenses are addressed at the same time – for example through switching tariffs and contracts, renegotiating or making other structural adjustments. Third: rules that are too strict, unclear or unrealistic increase the risk of rebound spending and feelings of guilt, thereby undermining the learning objective.
Context and attribution should be kept separate: the current occasion is 20minutos’ reporting of 22 August 2026 on the “retos de no comprar nada”. The scale of household expenditure is based on the INE’s latest publication of the Encuesta de Presupuestos Familiares for 2024. Forecasts of individual savings depend on each household’s profile and are not quantified here.
