For thousands of years, gold has survived the rise and fall of empires, currencies, and monetary systems. It has served as currency, supported international trade, and backed the value of national currencies. Today, central banks hold it as a reserve asset, investors buy it to preserve wealth, and much of the world's gold sits in vaults. Gold has retained its place in finance. What has changed dramatically, however, is how (little) we use it.
Gold was once money people could spend
Around 550 BC, King Croesus of Lydia, in modern-day Turkey, commissioned some of the earliest gold coins. These helped turn gold into a standardized form of money that could circulate through markets and economies. For centuries afterward, gold coins were used to pay for goods, settle debts, and conduct trade. As economies expanded and paper currencies emerged, gold continued to serve as the asset supporting confidence in monetary systems. By the late 19th century, many of the world's major currencies were tied to gold through the gold standard. Money could be exchanged for a defined quantity of gold, giving national currencies a common reference point. Gold had become the foundation of international finance
The world moved away from gold as everyday money
The 20th century fundamentally changed gold's relationship with money. Wars, economic crises, and changing monetary policies weakened the international gold standard. In 1944, the Bretton Woods system tied the US dollar to gold at $35 per ounce, while other participating currencies maintained fixed exchange rates against the dollar. That arrangement ended in 1971 when the United States suspended the dollar's convertibility into gold for foreign monetary authorities. Gold no longer served as the formal anchor of the international monetary system. Government-issued currencies increasingly took over the everyday functions gold had once performed.
Gold remained valuable, but its role narrowed
Gold did not disappear from finance. But rather, central banks continued holding it as a reserve asset. Investors bought bullion, coins, and investment products to diversify portfolios and preserve wealth. By the end of 2025, central banks held an estimated 38,600 tonnes of gold, worth approximately $5 trillion.
Yet for most holders, gold became an asset to buy, store, and eventually sell. Putting physical gold to work typically involves vaults, custodians, brokers, physical delivery, or additional financial arrangements. Its value can travel across centuries, but transferring and using the asset itself remains more complicated than moving digital money. This creates an interesting contradiction. One of the most enduring forms of money has become far less practical for everyday financial activity.
Gold's next chapter is about utility
The history of gold shows that its role has not been fixed, but has evolved alongside the financial systems built to use it. Blockchain infrastructure creates another opportunity for that evolution. Tether Gold has already brought ownership of physical gold onchain to make it as accessible as the rest of the internet. XAUT0 extends its reach across supported networks, creating opportunities for gold to move between financial applications and, where supported, be used in lending, trading, collateral, and treasury operations. Gold has spent centuries proving its value. The next chapter is about making that value useful again.
