What Is The Best Currency To Save In? A 55-Year Test Shows Three Options

What Happened

The Swiss franc was the strongest government-issued currency in the study. Yet even the franc failed to beat US inflation in most long holding periods. Gold protected purchasing power more often, while Bitcoin produced far higher returns over its much shorter history and charged investors with repeated crashes.

Market Context

There is no single best currency for every kind of saving. Our research found three assets with three different jobs: the US dollar for liquidity, gold for long-term insurance, and Bitcoin for high-risk upside.

We ran three return tests and then built a seven-part scorecard. All figures use data available through July 10, 2026. The charts draw on BeInCrypto Research calculations using the London Bullion Market Association, US Bureau of Labor Statistics, Federal Reserve H.10 exchange-rate series, IMF reserve data, World Gold Council, RWA.xyz, and CoinGecko. Individual claims link to supporting sources in the text.

Alongside those returns, we plotted an inflation line using the US Consumer Price Index. It shows how much $100 had to become to buy the same broad basket of goods and services. By July 2026, the answer was about $815.

The test measures the money itself. It excludes bank interest, bond yield, gold storage costs, trading fees, taxes, and other income or expenses. A dollar, therefore, remains a nominal $100 throughout the chart, even though its buying power falls.

Why It Matters

The research judged each form of money by four practical questions. Did it hold its value over time? Could a saver sell or use it during a crisis? How severe were the losses along the way? Could an owner move and control it without depending entirely on one institution?

Four of the nine assets could not take the full 1971 test. Bitcoin and the euro did not exist. The Chinese yuan was not freely tradable, and comparable Singapore dollar data starts later.

Details

The main lesson is simple. A saver first needs to decide what the money must do. Cash for next month’s bills has a different job from wealth meant to last for decades.

What “Best Currency” Means in This Study

People often use currency, cash, and savings as if they mean the same thing. They do not.

In this study, “money” includes seven government-issued currencies, gold, and Bitcoin. The seven currencies are the US dollar, euro, British pound, Swiss franc, Singapore dollar, Japanese yen, and Chinese yuan.

Gold and Bitcoin are not everyday currencies for most people. We included them because savers use both as alternatives to government money and because neither has a central issuer that can create more supply at will.

This produces a broader answer than a simple exchange-rate table. A currency can be stable and still lose purchasing power. An asset can deliver a large return and still be unsuitable for emergency savings.

How the Research Was Conducted

Test 1: What Happened to $100 from 1971?

The first test starts in 1971, when the United States ended the dollar’s convertibility into gold. That change marked the beginning of the modern system of freely floating government-issued currencies.

We asked what happened if a saver converted $100 into each available form of money in 1971 and held it until the study’s cutoff date. We then translated the final value back into US dollars.

This choice matters. A saver who held Treasury bills or an interest-paying account would have done better than someone holding banknotes. The same principle applies to interest earned on deposits in other currencies.

Test 2: A common starting point in 2013

We therefore repeated the exercise from the end of 2013. This gave all nine assets the same starting date and allowed Bitcoin to complete at least one full 10-year holding period.

In this test, $100 needed to become $144 to match US inflation. Bitcoin reached $8,381 and gold reached $342.

The Swiss franc finished at $110 and was the only fiat currency to beat the dollar, although it still missed the inflation target.

Test 3: Rolling five-year and 10-year periods

A single start date can flatter or punish an asset. Someone who bought gold near its 1980 peak had a very different experience from someone who bought it in 2001.
