The dollar remains king but the foundations of the global financial system may be starting to shift.
For more than 80 years, the US dollar has been the world's dominant currency.
Oil is largely priced in dollars. International trade is often settled in dollars. Central banks hold vast quantities of dollars in their reserves, and US government bonds have long been regarded as one of the safest investments in the world.
Despite periodic predictions of its decline, the dollar has remained remarkably resilient.
But a growing number of economic developments suggest that countries are quietly preparing for a future where they are a little less dependent on America's currency.
This is not a revolution.
It is more like a slow evolution.
Gold is back in fashion
One of the clearest signals has come from central banks.
For years, gold played a relatively modest role in many national reserves.
Today, central banks are buying gold at the fastest pace seen in decades.
Countries including China, India, Poland and Turkey have all increased their gold holdings.
Why?
Because gold carries no political risk.
Unlike foreign currencies, it cannot be frozen by another government, sanctioned or affected by the financial policies of another country.
For many central banks, gold has once again become an insurance policy.
The rise of alternative payment systems
Another important change is taking place behind the scenes.
Countries are increasingly exploring ways of trading directly in their own currencies.
China has encouraged greater use of the yuan in international trade.
India has expanded agreements allowing settlement in rupees.
Several members of the BRICS grouping have spoken about reducing reliance on the dollar for trade between member countries.
These initiatives remain relatively small compared with the enormous scale of dollar-based trade.
But the direction of travel is becoming clearer.
America still enjoys enormous advantages
It would be wrong to conclude that the dollar is about to lose its position.
Nothing currently comes close.
The United States still has:
the world's largest economy,
the deepest financial markets,
highly liquid government bond markets,
strong legal institutions,
and unmatched global financial influence.
When international crises occur, investors still tend to buy US dollars rather than sell them.
That is a remarkable vote of confidence.
So why are countries diversifying?
Because relying too heavily on any one currency carries risks.
The freezing of Russian foreign exchange reserves following the invasion of Ukraine demonstrated how financial assets can become part of international diplomacy.
Many governments took notice.
Even countries with friendly relations with the United States began asking sensible questions.
Should all their reserves be held in one currency?
Would greater diversification provide additional protection?
For many, the answer has been yes.
America's growing debt mountain
Another issue attracting attention is the size of US government borrowing.
The United States continues to run substantial budget deficits.
That means issuing enormous quantities of Treasury bonds each year.
As long as investors continue buying them, the system works smoothly.
But larger borrowing also means greater dependence on maintaining international confidence.
Countries such as Japan, China and the United Kingdom remain significant holders of US government debt.
Any gradual reduction in overseas demand could push borrowing costs higher.
Japan offers a glimpse of the future
Japan provides an interesting example.
For decades, Japanese interest rates were close to zero.
Investors therefore bought large quantities of higher-yielding US Treasury bonds.
Now that Japanese interest rates are rising, investors have more attractive opportunities closer to home.
There is little expectation of a dramatic sell-off.
Instead, economists are watching for something quieter but potentially more important:
a gradual rebalancing of global investment.
Technology may accelerate change
Digital payment systems and central bank digital currencies could also reduce dependence on the dollar over time.
Countries are experimenting with faster cross-border payment systems that allow trade without automatically passing through the US financial system.
Most remain in their early stages.
But they illustrate how technology may reshape international finance during the coming decade.
What could this mean for Britain?
For the UK, the dollar's future matters enormously.
Changes in the dollar affect:
import prices,
oil and gas costs,
inflation,
interest rates,
pension investments,
and financial markets.
If borrowing costs rise in America, they often influence borrowing costs elsewhere.
British homeowners, businesses and governments therefore have a direct interest in developments thousands of miles away.
A changing balance rather than a collapse
Some commentators predict the end of the dollar's dominance.
Others dismiss any challenge entirely.
The reality probably lies somewhere between those two extremes.
The dollar is unlikely to lose its reserve currency status any time soon.
There is simply no alternative with the same scale, liquidity and international trust.
But the world does appear to be becoming more diversified.
Instead of relying almost entirely on one currency, countries are slowly building a broader mix of reserves that includes gold, alternative currencies and new payment systems.
The next decade could reshape global finance
History shows that reserve currencies rarely disappear overnight.
The British pound did not lose its international role in a single event.
Its influence gradually diminished as economic power shifted.
The same is likely to be true if the dollar's dominance ever fades.
Rather than witnessing a dramatic collapse, we may instead be watching the early stages of a more balanced global financial system.
The United States will almost certainly remain at the centre of world finance for many years to come.
But central banks, governments and investors are increasingly behaving as though they believe it is wise to have a Plan B.
That may prove to be one of the defining financial stories of the next decade.
Whether the world is preparing for a post-dollar era or simply building greater resilience, one thing is becoming clear:
The architecture of global finance is beginning to change not through sudden upheaval, but through a series of quiet decisions that, taken together, could reshape the international economy for generations.
