BSP (Bank South Pacific) Exchange Rate API: PGK Buy and Sell Rates as JSON

Bank South Pacific is Papua New Guinea’s largest bank. Its exchange-rates page lists telegraphic-transfer and note rates in foreign currency per kina for about twenty currencies. This guide shows how to read that board as JSON: what the rates mean, how they compare with the Bank of Papua New Guinea official rate and with other banks in Papua New Guinea, and the calls that return them.

What the BSP board shows

• 22 currencies against the Papua New Guinean kina: AUD, CAD, CHF, CNY, DKK, EUR, FJD, GBP, HKD, INR, JPY, NOK, NZD, PHP, SBD, SGD, THB, TOP, USD, VUV, WST and ZAR. Every value is PGK per 1 unit of the foreign currency.
• The telegraphic transfer pair. The kina is managed against the US dollar and has been allowed to weaken in steps; banks print rates as foreign currency per kina. The rates here are the telegraphic-transfer pair converted to kina per unit. The Bank of Papua New Guinea official rate is shown next to each row.
• USD on 15 November 2026: BSP bought at 4.344 and sold at 4.6468 PGK, a spread of 6.74%.
• The bank's own timestamp. The page prints a last-updated stamp (Fri, 13 November 2026 on the board above), returned as bank_updated_at next to our captured_at.
• Every day's board is kept permanently, from 13 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 WST (2.46%), TOP (2.83%), FJD (2.99%) and the widest THB (19.48%), PHP (10.62%), CNY (10.41%). 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 Bank of Papua New Guinea rate is the one tax, accounting and customs rules in Papua New Guinea name; nobody transacts at it. BSP's board is the price a customer actually gets. Where the central bank has a rate for the same currency, the API returns it as official with vs_official_pct alongside; for Papua New Guinea that is the US dollar only. Use the Bank of Papua New Guinea endpoint when a rule asks for the official rate.

FAQ

Where do the BSP (Bank South Pacific) rates come from?

From the bank's own public rates page (https://www.bsp.com.pg/international-services/foreign-exchange/exchange-rates/), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price BSP shows, with the mid, the spread and the Bank of Papua New Guinea rate added.

Are these the official PGK exchange rates?

No. They are BSP's retail prices for customers. The official rate in Papua New Guinea is the Bank of Papua New Guinea 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 BSP 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 BSP rates for a past date?

Yes, from 13 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.
