Guangdong Nanyue Bank is a commercial bank headquartered in Zhanjiang, Guangdong. Its FX rates page lists settlement (buy) and purchase (sell) rates per 100 units for 5 currencies, with the effective time of each price. This guide shows how to read that board as JSON: what the rates mean, how they compare with the People’s Bank of China official rate and with other banks in China, and the calls that return them.

## What the Nanyue Bank board shows

- **5 currencies against the Chinese yuan**: EUR, GBP, HKD, JPY and USD. Every value is CNY per 1 unit of the foreign currency.
- **The settlement (结汇) / purchase (购汇) rates, transfer pair.** The People’s Bank of China sets a daily central parity for the yuan, but the rate a customer gets is a bank’s board, and Bank of China’s is the one most quoted. Chinese banks publish spot-exchange (transfer) and cash columns, quoted per 100 units of foreign currency; the pair here is spot exchange, shown per 1 unit.
- **USD on 15 November 2026**: Nanyue Bank bought at 6.6578 and sold at 6.6858 CNY, a spread of 0.42%. The People’s Bank of China official rate was 6.7152, so the bank's mid sat -0.65% from it.
- **The bank's own timestamp.** The page prints a last-updated stamp (`2026-11-14 03:00:05 (Beijing)` on the board above), returned as `bank_updated_at` next to our `captured_at`.
- **Every day's board is kept permanently, from 14 November 2026.** 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 tightest spreads were USD (0.42%), HKD (0.42%), GBP (0.59%) and the widest JPY (0.77%), EUR (0.63%), GBP (0.59%). 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.

## Board rate or official rate?

The People’s Bank of China rate is the one tax, accounting and customs rules in China name; nobody transacts at it. Nanyue Bank'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 [People’s Bank of China endpoint](https://allratestoday.com/central-bank-rates-api/pboc/) when a rule asks for the official rate.

## FAQ

### Where do the Guangdong Nanyue Bank rates come from?

From the bank's own public rates page (https://www.gdnybank.com/api/dispalyExchange.jspx), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price Nanyue Bank shows, with the mid, the spread and the People’s Bank of China rate added.

### Are these the official CNY exchange rates?

No. They are Nanyue Bank's retail prices for customers. The official rate in China is the People’s Bank of China 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 Nanyue Bank board updated?

AllRatesToday reads the page every hour. The bank's own last-updated stamp is returned as `bank_updated_at`, so you can tell a fresh read of an unchanged board from a new board.

### Can I get Nanyue Bank rates for a past date?

Yes, from 14 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.
