I’ve been thinking about a question lately: why has inflation become the top concern worldwide in recent years? When I looked through the data, I finally understood that inflation’s impact runs far deeper than we think.

Simply put, inflation means money is becoming less valuable. This year, your 100 dollars can buy ten items; next year, it might only buy eight. This isn’t something new, but in the past few years it has definitely gotten worse. In 2022, the US CPI rose 9.1% year-over-year, reaching a 40-year high. Europe was even worse—at one point it exceeded 10%.

Why is this happening? At its root, there is too much money and too few goods. As demand increases, costs rise, and central banks print excessive amounts of money—along with people expecting prices to rise—everyone starts rushing to buy things, and the more they buy, the more prices go up. This becomes a vicious cycle.

What can central banks do? Raise interest rates. In 2022, the Federal Reserve raised rates 7 times in one go. Interest rates jumped from 0.25% to 4.5%. The logic is straightforward: borrowing becomes more expensive, so people are less willing to borrow and are less likely to spend wildly. Demand falls, and prices naturally come down. But the price is high too—rising interest rates caused a sharp sell-off in the stock market. The S&P 500 fell 19%, and the Nasdaq dropped 33%. Many people lost their jobs, and economic growth stalled.

Interestingly, inflation isn’t entirely a bad thing. Moderate inflation can stimulate consumption and investment. Think about it: if things will be more expensive next year, you’d have to buy sooner this year. That boosts demand, and companies expand production, so the economy grows as well. China experienced this in the early 2000s: CPI rose from 0 to 5%, and GDP growth also increased from 8% to over 10%. The opposite lesson comes from Japan, though—after the economic bubble burst in the 1990s, Japan fell into deflation. Prices stagnated, people only wanted to save and didn’t want to spend, and as a result GDP turned negative growth, leading to the “Lost Thirty Years.”

So central banks around the world are working hard to keep inflation within a reasonable range of 2%–5%—ensuring there’s momentum for growth while preventing prices from getting out of control.

The question now is: in an inflationary age, how do we protect our money? People with debt may actually benefit. For example, if you borrowed 1,000,000 to buy a house 20 years ago, then in a 3% inflation scenario, that 1,000,000 would only be worth 550,000 after 20 years—effectively repaying the house at half price. But most people don’t have that much debt. What should they do?

Invest. Stocks, gold, real estate, and the US dollar are all good choices for hedging against inflation. In 2022, the US stock market energy sector saw a return of over 60%. Western Petroleum rose 111%, and ExxonMobil rose 74%. Gold is a classic safe-haven asset—when inflation is higher, gold tends to perform better. Real estate is also not bad. During periods of inflation, more liquid money flows into the market, and a lot of it pours into real estate, pushing up home prices.

If I were to make a recommendation, I’d suggest diversifying your allocation: 33% in stocks, 33% in gold, and 33% in the US dollar. In this way, you can benefit from stock market growth while also enjoying the value-preservation effects of gold and the US dollar—spreading risk and resisting inflation erosion at the same time.

One last piece of advice: don’t put all your money in the bank. In an inflationary era, cash is the most devaluing asset. When the time is right, take action—allocate your money into assets that can withstand inflation. That’s the smartest way to deal with inflation.
