The Dollar Tax: What It Costs to Route EUR→TRY Through New York
The short answer
When you move euros to lira through a typical bank or payment provider, the money is almost never converted EUR→TRY directly. It is converted EUR→USD, parked, then USD→TRY. You pay a spread on both legs. The dollar in the middle is not free — it is a second transaction you never asked for, and on a non-dollar corridor it is pure overhead.
Why the dollar is in the middle at all
The global banking system is wired around USD. Most currencies have deep, liquid markets against the dollar and thin, fragmented markets against each other. A correspondent bank in Frankfurt does not keep a continuous EUR/TRY book the way it keeps EUR/USD. So when a German importer pays a Turkish supplier, the path of least resistance inside the old plumbing is: sell EUR for USD, send USD to a US correspondent, sell USD for TRY. Two conversions, two spreads, two settlement windows.
The provider is not trying to charge you extra. The dollar leg is a side effect of an infrastructure built for a dollar-centered world. But you still pay for it.
What the second spread costs
Cross-border payments on correspondent banking typically run an all-in cost of roughly 1.5–3% across legs. On a direct pair that is one spread. On a routed pair you are effectively paying for two. A conservative read:
| Route | Conversions | Indicative cost |
|---|---|---|
| EUR→TRY (routed via USD) | 2 (EUR→USD, USD→TRY) | ~1.5–3% all-in |
| EUR→TRY (direct) | 1 | one spread, quoted up front |
On a €100,000 supplier payment, the difference between one spread and two is not rounding error. It is the kind of money that gets negotiated into margin on every invoice.
Who takes it
The spread is shared across the chain: the originating bank, the US correspondent that holds the dollar leg, and the destination bank. None of them set out to add a "dollar tax" — it is just how the rails are priced. The point is not blame. The point is that the cost is structural, and it disappears the moment the conversion is direct.
Why almost every provider builds it in
If your settlement layer is correspondent banking, you inherit its topology. You cannot offer EUR→TRY natively without holding TRY liquidity, maintaining a TRY corridor, and taking the operational risk of a market you may only touch occasionally. So the product is built around the USD hub, and the dollar leg is invisible to the customer until they price the job.
A stablecoin settlement layer changes the topology. The stablecoin is the intermediary instead of a bank in a third country. EUR and TRY can meet on the rail directly — both legs native, one spread, quoted before you commit, 24/7 including weekends and bank holidays.
What to ask your provider
- Is this pair settled directly, or routed through USD?
- How many conversions am I paying a spread on?
- Is the rate quoted before I commit, or filled at execution?
- Does settlement run on weekends, or only business days?
Money doesn't observe banking hours. Neither should its cost.
The bottom line
The "dollar tax" is not a fee a provider adds. It is the structural cost of a payment network designed around one currency. On non-dollar corridors — EUR/TRY, AED/INR, PLN/GBP, ZAR/EUR — it is paid by people who never wanted a dollar in the first place. A direct pair removes it.
What is the dollar tax on currency conversion?
On a non-dollar corridor like EUR→TRY, the payment routes through USD: EUR→USD then USD→TRY. Each leg carries a spread, so you pay twice to move between two non-dollar currencies. That second spread is the dollar tax.
Why do international payments take 2–4 days?
The delay is the correspondent banking chain: your bank, an intermediary, and the beneficiary's bank each reconcile the USD leg in batches. A stablecoin settlement leg does the cross-border portion in minutes; only the local off-ramp takes what banking takes.
How many currencies can a stablecoin platform settle?
It depends on the model. A provider that owns its rails typically settles 2–3 currencies. A technology layer that connects to licensed institutions can reach 35+, because adding a currency is a configuration, not a new banking licence.
