USD to DOP for business payments
To pay a Dominican supplier in pesos, convert US dollars to Dominican pesos (DOP) and pay its peso account; to pay in dollars, wire USD to its dollar savings account or, often, to its account abroad. Dominican law guarantees free convertibility and a free exchange market, so the choice is commercial. This page covers how the peso's rate is set, the account rules that surprise foreign buyers, the details to collect, the costs and how to choose.
- The Monetary and Financial Law 183-02 establishes free convertibility of the Dominican peso and provides that monetary and financial operations take place under free market conditions.
- The BCRD publishes daily buying and selling rates for the US dollar, calculated as the weighted average of that day's spot market transactions, under Article 61 of the exchange regulation of Law 183-02.
- Under Law 183-02, multiple banks may take savings and time deposits in foreign currency, but demand deposits are in pesos, and the US government's guide states there are no local checking accounts in US dollars.
- The US International Trade Administration states that most Dominican companies maintain dollar accounts abroad.
- Only authorized financial intermediaries and exchange agents may intermediate foreign exchange in the Dominican Republic, and the Central Bank cannot require exchange operations to go through it.
The Dominican peso and how its rate is set
The Dominican peso (code DOP, written RD$) is issued by the Banco Central de la República Dominicana (BCRD). Its exchange regime is set by Law 183-02, the Monetary and Financial Law, which establishes the principle of free convertibility of the peso with other currencies and provides that monetary and financial operations take place under free market conditions. The Central Bank cannot require exchange operations to go through it, and only authorized financial intermediaries and exchange agents (agentes de cambio) may intermediate foreign exchange.
The BCRD still publishes a reference. Each day its treasury department issues the Central Bank buying and selling rates for the US dollar, under Article 61 of the exchange regulation of Law 183-02. They are the weighted average of that day's spot market transactions, excluding derivatives, and serve as the reference for the BCRD's own operations until the next day. Banks and exchange agents set their own rates around it.

Account rules that shape a payment
The rule that surprises foreign buyers is about account types. Under Law 183-02, multiple banks (bancos múltiples), the full-service commercial banks, may receive demand deposits in national currency and savings and time deposits in national and foreign currency. The Country Commercial Guide, last published on 17 March 2026, puts it in practical terms: there are no local checking accounts in US dollars, and local banks offer savings accounts in US dollars.
- Where your dollars land. A dollar payment to a Dominican bank goes into a dollar savings account. Ask the supplier which account to use, because a payment sent to its peso account is converted by the bank.
- Accounts abroad. The same guide states that most Dominican companies maintain dollar accounts abroad. A Dominican supplier asking to be paid outside the country is common, but confirm any new bank details by phone with a contact you already know.
- No standing inflow control. The Monetary Board may temporarily limit short-term foreign capital inflows, for no more than one year at a time. It is a power held in reserve, and it does not concern payments for goods.
Inside the country, the BCRD operates the national payment system, which includes a real-time gross settlement system (LBTR) and an instant payments service, the rails a provider uses for a peso payout.
Details you need to pay a Dominican supplier
A SWIFT payment to a Dominican bank needs the bank's SWIFT code and the supplier's account number in the format its bank gives for incoming wires. A Dominican account has no US routing number, so a US buyer cannot pay it by ACH or Fedwire.
| Field | For a dollar wire | For a peso payment |
|---|---|---|
| Beneficiary name | Registered name exactly as on the account, matching the RNC | Same |
| Account number | The dollar savings account number | The peso account number |
| Bank identifier | Bank's full name, address and SWIFT code | Bank name, for a local payout |
| Intermediary bank | The US correspondent the supplier's bank names | Not needed |
| Reference | Invoice number | Invoice number |

The RNC (Registro Nacional de Contribuyentes) is the taxpayer number issued by the DGII, the tax authority. Use it to check that the account holder is the company that invoices you.
What converting USD to DOP costs
A conversion costs the mid-market rate plus the margin of whoever converts, plus the payment fee. Because each bank and exchange agent quotes its own rate in a free market, the BCRD's published buying and selling rates are the benchmark to compare against. A 1% difference in rate costs $100 on every $10,000 converted.
If you pay dollars into the supplier's dollar savings account, there is no conversion on your side; the supplier sells dollars for pesos when it chooses. Ask it whether its savings account limits transfers out, which matters if it needs to pay its own suppliers abroad from the same balance.

Pay in USD or in DOP?
| Situation | Better choice | Why |
|---|---|---|
| Free zone manufacturer or exporter invoicing in USD | USD | No conversion; dollars can stay in a savings account or abroad |
| Supplier's costs and price list are in pesos | DOP | It receives the exact amount; you carry the exchange risk |
| Supplier gives a peso account for a USD invoice | Ask for the dollar savings account | Otherwise its bank converts at its own rate |
| Supplier asks to be paid to an account abroad | Verify by phone | Common practice, and also a common fraud pattern |
