When a company in China sends samples to the United States, when an online store in Europe delivers an order to Brazil, when a law firm forwards documents between London and Singapore — all these shipments are handled by global courier services that operate in dollars.

The global express delivery market exceeds $300 billion a year, and U.S. companies control a significant share of it.

UPS and FedEx are American, DHL is German, but its international settlements often go through dollars. Rates, insurance, customs fees, and customer service are denominated in U.S. currency. Courier services are another invisible pillar of the dollar, about which almost nobody speaks.

Why Courier Services Operate in Dollars

International shipping is one of the most globalized industries. A parcel from Shanghai to São Paulo, documents from New York to Dubai, samples from Berlin to Tokyo — this is daily reality for millions of companies. Such an industry needs a currency that is accepted everywhere. Historically, that currency has been the dollar.

The reason is simple: the largest courier companies are American. UPS and FedEx are based in the United States. Their rates, customer contracts, and internal accounting are denominated in dollars. Even DHL, a German company, often uses dollar settlements for international shipments because its biggest clients are global corporations that operate in U.S. currency.

Moreover, customs duties, cargo insurance, and returns processing frequently go through dollar accounts. The biggest logistics hubs are in the United States, Europe, and Asia, but their financial operations are tied to the dollar system.

How Courier Services Create Demand for Dollars

Every time a company ships an international parcel, it pays for the delivery in dollars. Even if the sender is in Europe and the recipient in Asia, the settlement often goes through U.S. currency

For the United States, the courier industry is not only UPS and FedEx. It also includes banks that finance their operations and process payments. JPMorgan, Citigroup, Bank of America — all of them work with courier companies. This creates additional capital flows in dollars.

For the dollar, courier services are a steady source of demand. Even if other factors weaken, people will always be sending parcels and documents. This makes the U.S. currency more resilient than one might expect.

For developing countries, the courier industry is a challenge. Companies are forced to buy dollars to pay for international shipping. This creates pressure on their national currencies and increases dependence on the U.S.

What this means for the dollar

Courier services are an inconspicuous but important pillar of the dollar. They create steady demand for the U.S. currency that does not depend on Fed rates or geopolitics. As long as the world ships parcels, the dollar will receive support.

However, this pillar has a weak spot. If China or other countries create their own competitive courier networks and begin promoting them in yuan, this could gradually undermine the dollar’s monopoly. China is already developing its logistics infrastructure and international delivery services.

What this means for the average person

If you order goods from abroad or send parcels, you are already part of this system. Shipping costs include dollar expenses that support the U.S. economy.

For those holding savings in dollars, the courier industry provides additional support. For those working in logistics or e‑commerce, it means understanding how global capital flows affect exchange rates.

What’s next

The global express‑delivery market will grow. E‑commerce is expanding, global supply chains are becoming more complex, and consumers expect fast delivery. This means that demand for dollars in the industry will only increase.

For the dollar, this means it has another steady pillar that will not disappear in the coming decades. Even if other factors weaken, courier services will remain a quiet haven for the U.S. currency.
