The dollar’s monopoly in payments will soon be history

THE social-media video where Donald Trump’s AI avatar is may be just a spoof on the US president’s quixotic bid to reindustrialize America by eliminating bilateral trade deficits. But the meme contains a kernel of truth. The world’s farmers, fishermen, and factory workers labor hard to earn the $100 bill that the Federal Reserve prints at no cost. This exalted status, which a French politician from the 1960s termed as the dollar’s has been taken to a breaking point by the tariff war.

No matter what happens in the long run to the US currency’s value or its role as a safe haven for central banks and private investors, one thing is clear: The greenback’s monopoly in payments, whereby it’s exchanged in , is headed for the history books. A weekend trip to Vietnam brought that home to me.

In Hoi An, a 15^th century trading port repurposed as a tourist attraction, tailors and shoemakers pay for visitors’ taxi rides to their shops and shell out commissions to hotels for directing guests their way. If they didn’t have to charge customers a 3% credit-card fee, they might be able to do more to nudge inveterate shoppers. For instance, they could raise their prices by 1% and still throw in a dinner voucher for high spenders — if they purchase one more linen shirt. The buyers will be richer, as will the sellers.

The reason they can’t fund such sales promotions is the dollar. Or, to be more precise, a financial architecture built around the idea that a payment made on a foreign credit or debit card must set off a chain of expensive activity underpinned by the greenback. For that settle without much friction, those costs are negligible. But for the Vietnamese dong, and most other Asian currencies, they’re a burden, which a highly competitive apparel and footwear industry working on tight margins can’t absorb. So it passes on all of it — and sometimes more — to a buyer who would much rather take the free meal. 

Take my example. To pay the tailor in Hoi An, my bank had to obtain the local currency, which doesn’t have a liquid market outside Vietnam. So my money most probably got converted into dollars in Hong Kong. After reaching Vietnam, the funds got exchanged again into Vietnamese dong. Almost 40% of the greenback’s $7.5 trillion daily turnover comes from its role as a vehicle of value. Neither the buyer nor the seller has any direct interest in it. Yet they can’t transact without it.

Trump is aware of America’s special status: He has even countries looking to come up with alternative global reserve currencies with 100% tariffs. A high-profile disengagement with the dollar — for instance, when it comes to Saudi Arabia’s — may not go down well with Washington. What the White House can’t control, however, are low-profile shifts in the engine room of the payment industry. Even before Trump’s inauguration, I that the world of money was splintering into Western and Eastern blocs. The trade war may have accelerated the schism, though the separation is now more likely to be along a US/non-US axis than a West/East split.

I can already pay a in baht from my Hong Kong bank account by scanning a QR code. Vietnam to establish similar connectivity with Singapore. These links are between commercial institutions, with third parties providing foreign-exchange services. However, some central banks in Europe are working with their counterparts in Asia to explore automated conversion using blockchain technology. If the pilots succeed, there may be no room for middlemen — software embedded in digital representations of fiat currencies will act as moneychangers. Ergo, there may be no need for the dollar to act as a go-between in transactions that don’t involve Americans. 

This is just one of the underway to boost the efficiency of cross-border retail payments. They’re underpinned by $800 billion in remittances by overseas workers. And then there’s what tourists spend. In Asia, they’re staying 7.4 days on average, 1.3 days more than before the pandemic, according to Mastercard, Inc.’s . For a small business in a lesser-known beach town competing against larger firms in more popular holiday destinations, each hour is valuable — and an expensive payment system an irritant. It has been tolerated so far because nothing cheaper was available, and Asian policymakers’ focus was on shipping goods to the US, a much larger opportunity.

But everything has changed since the April 2 reciprocal tariffs. Chinese President Xi Jinping just as I was leaving. Beijing has been pushing the so-called mBridge initiative in which financial institutions can swap digital currencies issued by their central banks to settle cross-border claims. If the Trump administration is going to upset friends and foes alike to pursue a chimerical vision of labor-intensive industrialization, then it has to be prepared for geopolitical realignments, and an erosion of at least one form of America’s exorbitant privilege.

Those who still view the dollar as a relatively safe asset may want to hold it, as long as the US remains the world’s predominant superpower. But for tourists buying shoes or shirts in Vietnam, the 3% extra charge on payments is an avoidable, anticlimactic loss after haggling for — and winning — a nice discount on the merchandise.

Rather than incurring outsize fees to Visa, Inc. and its partner banks, a dinner at Hoi An’s Morning Glory restaurant seems like a fairer use of my money — while I wait for the last buttons to be sewed on.
