A few years ago, 2022 was that pivotal moment when inflation spiraled out of control in Europe and the United States. Central banks had no choice but to aggressively raise interest rates, a scenario we hadn't seen in decades. And with that came an interesting economic discussion: what does deflated mean and why does it matter for our wallets.

Deflation adjustment is basically a correction made by economists to compare real data over time, removing the noise caused by inflation. Imagine your salary increases by 5%, but inflation also rises by 5%. In nominal numbers, it looks like you earned more, but in reality, your purchasing power remains the same. That’s why we need to understand what deflated means: it’s the real value after removing the effect of prices.

In Spain, during that inflation crisis, politicians started debating about deflating the IRPF, the income tax. The idea was simple: if taxpayers receive nominal salary increases but inflation erodes them, tax brackets should be adjusted so they don’t pay more taxes for earning more nominally. Other countries like the United States, France, and Germany already do this regularly. In the U.S., they even do it annually. But in Spain, at the national level, it hadn’t been done since 2008.

What’s interesting is that many people don’t really understand what deflated means in practical terms. Basically, it’s recognizing that 100 euros today are not worth the same as 100 euros three years ago. When you deflate economic data, you’re normalizing everything to a base year to make fair comparisons. For example, if a country’s GDP grows nominally by 20%, but prices have risen by 10%, the real growth was only 10%. That’s what deflated means: the number adjusted for inflation.

Now, how does this affect our investments? If IRPF is deflated, you potentially have more money available to invest. With greater purchasing power, you might consider different strategies depending on the economic context.

In times of high inflation, many investors turn to safe-haven assets like gold, which historically maintains its value. Stocks can be tricky because financing costs for companies increase, but some sectors resist better, such as the energy sector. Diversifying into Treasury bonds or exploring currency markets is also an option, though the latter is quite volatile and requires experience.

What needs to be understood is that the actual economic benefits of deflating IRPF for an average person are not spectacular. We’re talking about savings of a few hundred euros a year, not thousands. So, while it’s important to understand what deflated means and how it works economically, it’s not the panacea some present it to be.

The key is to see the full picture: inflation, interest rates, fiscal policies, and how all this influences your investment decisions. Understanding these concepts, even what deflated means at a technical level, helps you make more informed choices about where to put your money across different economic cycles.
