Banco Múltiple López de Haro is a Dominican commercial bank based in Santo Domingo. Its home page lists its buying and selling prices for the US dollar and the euro. This guide shows how to read that board as JSON: what the rates mean, how they compare with the Banco Central de la República Dominicana official rate and with other banks in the Dominican Republic, and the calls that return them.

## What the López de Haro board shows

- **2 currencies against the Dominican peso**: EUR and USD. Every value is DOP per 1 unit of the foreign currency.
- **The branch buy / sell pair.** Dominican banks post a buying and selling price in pesos per US dollar and euro. The Banco Central de la República Dominicana publishes a daily reference rate from market trades. The Banco Central de la República Dominicana official rate is shown next to each row.
- **USD on 15 November 2026**: López de Haro bought at 59.3 and sold at 61.4 DOP, a spread of 3.48%. The Banco Central de la República Dominicana official rate was 60.8132, so the bank's mid sat -0.76% from it.
- **No timestamp on the bank's page.** López de Haro does not print a last-updated time, so `bank_updated_at` is `null` and `captured_at` (when AllRatesToday read the page) is the only time available.
- **Every day's board is kept permanently, from 15 November 2026, the day collection started.** Read one past day with `?date=`, or a range for one currency with the `/history` endpoint (paid plans).

## Spreads across the board

On the 15 November 2026 board the spreads were USD 3.48%, EUR 5.88%. Spread is (sell − buy) ÷ mid: what a round trip through the bank costs, before any fees. The API returns it on every row as `spread_pct`, so you can rank currencies or alert when a bank widens its board.

## USD at López de Haro and other banks in the Dominican Republic

USD on the 4 boards AllRatesToday reads in the Dominican Republic, all captured on 15 November 2026 (the Banco Central de la República Dominicana official rate was 60.8132):

| Bank | Buy | Sell | Spread | Mid vs official |
| --- | --- | --- | --- | --- |
| **Banco López de Haro** | 59.3 | 61.4 | 3.48% | -0.76% |
| Scotiabank República Dominicana | 58 | 61.45 | 5.78% | -1.79% |
| Banco LAFISE República Dominicana | 58.75 | 61.45 | 4.49% | -1.17% |
| Banco Vimenca | 59.4 | 61.4 | 3.31% | -0.68% |

López de Haro had the 2nd narrowest USD spread of the 4. One call to `/api/v1/bank-rates/do` returns every board in the table at once.

console.log(`López de Haro buys USD at ${r.buy}, sells at ${r.sell} DOP`);

// The board as it stood on a past day
const past = await client.bankRates('do', { bank: 'lopezharo', date: '2026-11-15' });
console.log(past.snapshot_date, past.rates.length);

## Board rate or official rate?

The Banco Central de la República Dominicana rate is the one tax, accounting and customs rules in the Dominican Republic name; nobody transacts at it. López de Haro's board is the price a customer actually gets. The API puts both on every row: `official` is the central bank's rate for the same currency and `vs_official_pct` is how far the bank's mid sits from it. Use the board to show customers a real price, compare banks for a remittance, or keep a dated record of what the bank quoted; use the [Banco Central de la República Dominicana endpoint](https://allratestoday.com/central-bank-rates-api/bcrd/) when a rule asks for the official rate.

## FAQ

### Where do the Banco López de Haro rates come from?

From the bank's own public rates page (https://www.blh.com.do/), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price López de Haro shows, with the mid, the spread and the Banco Central de la República Dominicana rate added.

### Are these the official DOP exchange rates?

No. They are López de Haro's retail prices for customers. The official rate in the Dominican Republic is the Banco Central de la República Dominicana rate, which the API returns as `official` on each row where the central bank has one, and in full from the central-bank endpoint.

### How often is the López de Haro board updated?

AllRatesToday reads the page every hour. The bank prints no timestamp, so `captured_at` tells you when the rates were read.

### Can I get López de Haro rates for a past date?

Yes, from 15 November 2026 onward; every day's board is kept permanently. Add `?date=YYYY-MM-DD` for one day: the response is the board captured that day, or the nearest earlier day within five days, with `date_requested` and `snapshot_date` added. For a range, `/history?ccy=USD&from=…&to=…` returns one row per day as JSON, CSV, XML or XLSX on paid plans.

### Do I need an API key?

Yes. Commercial bank boards need an API key; any plan works, the free key included, and each call counts against the plan. Public pages or widgets that show the rates need a visible link to allratestoday.com.
