Understanding the SOS/SAR Exchange Rate

The SOS/SAR exchange rate tells you how many Saudi riyals you get for 1 SOS. This is the mid-market rate — the real exchange rate without any markup. It's the same rate used by Google Finance.

AllRatesToday provides this rate via a free REST API, updated every 60 seconds from institutional interbank market data. Integrate live SOS/SAR rates into your app with our official SDKs for JavaScript, Python, PHP, and React.

The exchange rate between SOS and SAR fluctuates based on supply and demand in the foreign exchange market. Economic data releases, central bank announcements, and geopolitical events can all cause significant movements in the rate.

Currency converter API for SOS to SAR

This converter is a thin layer over two APIs. Both return JSON, both take one HTTP call, and both have a free tier — no credit card.

  -H "Authorization: Bearer YOUR_API_KEY"

[{ "rate": 0.8643, "source": "SOS", "target": "SAR",
   "time": "2026-08-16T11:01:24+0000" }]
  • Several targets at once — target=SAR,GBP,JPY returns one row per pair in a single call.
  • Historical — /api/historical-rates for a date range, or ?time=YYYY-MM-DD for one past day.
  • Four formats — add ?format=csv, xml or xlsx to get a file instead of JSON.

Central bank rate API

The rate a named institution actually published for a given date, from 116 central banks and 3 tax authorities. Unlike a mid-market rate it never changes after publication, which is what tax filings, customs valuations and audits require. 

curl "https://allratestoday.com/api/v1/central-bank/ecb/latest?source=SOS&target=SAR" \
  -H "Authorization: Bearer YOUR_API_KEY"

{ "bank": "ecb", "rate_date": "2026-08-14", "rate": 0.8643,
  "rate_type": "reference", "derived": false, "method": "published" }
  • Any past date — /central-bank/{bank}/2026-06-30. If the bank did not publish that day you get the most recent prior date, flagged.
  • Every bank at once — /api/v1/central-banks/rates returns all sources for one pair, so you can compare what each institution published.
  • Nothing is guessed — pairs a bank does not print are cross-computed from that bank's own table and returned with "derived": true and the method used. Banks are never mixed.

Which one do you need? If a regulator, tax authority or auditor names the source, use the official rate — the two can differ by several percent on the same day. For everything a customer sees, use the mid-market rate. On weekends and holidays the official endpoints return the most recent published date, which is the figure compliance rules expect you to apply.

Official SOS and SAR Central Bank Rates

How SOS/SAR Exchange Rates Work

Exchange rates are determined by supply and demand in the global foreign exchange (forex) market, the largest financial market in the world with over $6 trillion traded daily.

Floating vs Fixed Rates: Most major currencies like SOS and SAR have floating exchange rates, meaning their value is determined by market forces. Some currencies are pegged to another currency (usually USD) at a fixed rate.

Bid and Ask Prices: In forex markets, currencies are quoted with a bid price (what buyers pay) and ask price (what sellers receive). The mid-market rate shown on this page is the midpoint between these two prices.

Rate Fluctuations: The SOS/SAR rate can change every second during trading hours. Major economic announcements, interest rate decisions, and geopolitical events can cause significant moves in either direction.
