Nabil Bank Exchange Rate API: NPR Buy and Sell Rates as JSON

Nabil Bank, established in 1984 as Nepal’s first private-sector bank, is one of the country’s largest commercial banks. Its forex page lists daily cash buying, non-cash buying and selling rates for about 20 currencies, with the time of the update. This guide shows how to read that board as JSON: what the rates mean, how they compare with the Nepal Rastra Bank official rate, and the calls that return them.

What the Nabil Bank board shows

21 currencies against the Nepalese rupee: AED, AUD, BHD, CAD, CHF, CNY, DKK, EUR, GBP, HKD, JPY, KRW, KWD, MYR, OMR, QAR, SAR, SEK, SGD, THB and USD. Every value is NPR per 1 unit of the foreign currency.
The non-cash buy / sell pair. The Nepalese rupee is pegged to the Indian rupee at 1.6 per INR, so other currencies move with the rupee’s cross against INR. Nepal Rastra Bank sets official buying and selling rates each day, and commercial banks post their own boards around them, usually with separate cash and non-cash buying rates and one selling rate. The pair here is the non-cash buy and the sell.
USD on 13 November 2026: Nabil Bank bought at 150.4 and sold at 151 NPR, a spread of 0.40%. The Nepal Rastra Bank official rate was 150.78, so the bank's mid sat -0.05% from it.
The bank's own timestamp. The page prints a last-updated stamp (2026-11-13 09:54:09 (Kathmandu) 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, 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 13 November 2026 board the tightest spreads were USD (0.40%), SAR (0.48%), BHD (0.49%) and the widest SGD (0.99%), GBP (0.99%), AUD (0.99%). 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 Nepal Rastra Bank rate is the one tax, accounting and customs rules in Nepal name; nobody transacts at it. Nabil 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 Nepal Rastra Bank endpoint when a rule asks for the official rate.

FAQ

Where do the Nabil Bank rates come from?

From the bank's own public rates page (https://www.nabilbank.com/currency), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price Nabil Bank shows, with the mid, the spread and the Nepal Rastra Bank rate added.

Are these the official NPR exchange rates?

No. They are Nabil Bank's retail prices for customers. The official rate in Nepal is the Nepal Rastra Bank 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 Nabil 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 Nabil Bank 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.
