What is SARIE?
SARIE (Saudi Arabian Riyal Interbank Express) is Saudi Arabia's real-time gross settlement (RTGS) system, which settles Saudi riyal payments between banks one by one, in real time. It is run by the Saudi Central Bank (SAMA) and has been live since May 1997.
The name now covers two systems. Alongside the RTGS, SAMA launched an instant payment system called sarie in February 2021, built for low-value transfers that arrive in seconds at any hour. Payout providers, including Due, use the instant system to send SAR to Saudi bank accounts.
What is the difference between SARIE and sarie?
The two systems share a name but do different jobs. SAMA's own branding uses capitals for the RTGS and lowercase for the instant system:
- SARIE (RTGS): settles payments between banks in real time, and SAMA says "all transfers to beneficiaries of all categories pass" through it
- sarie (instant payments): lets customers send transfers under SAR 20,000 that are credited to the recipient instantly, 24/7, according to SAMA's launch announcement
In practice, SARIE is the settlement backbone that banks run on. sarie is the customer-facing rail for everyday transfers, much like the UK's Faster Payment System or India's UPI.
How does the SARIE RTGS work?
SARIE follows the standard real-time gross settlement model. Each payment settles on its own, in full, as soon as the sending bank has the funds. The BIS's 2012 review of Saudi payment systems set out how it worked at the time:
- Central bank accounts: banks settle through the accounts they hold at SAMA
- Finality: settlement is final and irrevocable, so a settled payment can't be pulled back
- Intraday credit: banks could draw intraday overdrafts from SAMA, fully backed by Saudi government securities
- Queuing: payments waited in a queue until the sending bank had enough liquidity
SARIE also settles for other national systems. Per SAMA's payment systems rulebook, these include mada (cards and ATMs), SADAD (bill payments), the ACH (cheque clearing), and Tadawul (the stock exchange). That makes it the point where Saudi interbank settlement comes together.
How does the sarie instant payment system work?
Saudi Payments launched sarie under SAMA's supervision, according to IBM's launch release. The system uses Mastercard's real-time payments technology and is built on ISO 20022 messaging. Its main features are:
- 24/7 transfers: customers can send and receive low-value transfers around the clock
- Aliases: a sender can pay a mobile number, email address, or ID number instead of an IBAN, once the recipient has opted in
- Account check: the sender can confirm the recipient's account is valid before sending
- Low fees: SAMA said fees for low-value transfers would not exceed one Saudi riyal
The account check works much like a penny test, confirming the details before real money moves. Individual banks publish their own fees. Riyad Bank, for example, charges SAR 0.50 up to SAR 500 and SAR 1 up to SAR 20,000, before VAT.
What are the sarie transfer limits?
sarie has two limits, and both affect how payouts are planned. SAMA set them at launch:
- SAR 20,000: transfers below this amount are credited to the recipient instantly
- SAR 2,500: quick transfers below this amount don't need the recipient saved as a beneficiary first
Payments above SAR 20,000 still go through, just not instantly. Riyad Bank says they are "processed through normal local bank transfer method without any change." Each bank also controls the quick transfer limit for its customers. At Riyad Bank, it starts at zero until the customer raises it.
For a business, the practical rule is simple. Keep payouts under SAR 20,000 when speed matters, and expect larger payments to follow standard bank timing.
How is sarie growing?
sarie is part of a wider shift away from cash in Saudi Arabia. In a September 2025 speech, SAMA Assistant Governor Abdulelah Aldeheem said electronic payments grew from 18% of retail payments in 2015 to 79% in 2024. He added that mada, sarie, and SADAD together processed around 12.8 billion transactions in 2024.
SAMA's next step is wider scope. Aldeheem said SAMA is expanding the instant payment system "to include a greater range of payments," and he named expanded sarie features as an area for future work. As the system expands, it's worth rechecking the limits above before building a payout flow around them.
What details do you need to pay a Saudi bank account?
The IBAN is the main identifier for Saudi bank accounts. According to SAMA's IBAN checker, "All Saudi IBANs begin with 'SA' and are exactly 24 characters long."
Aliases are convenient for people paying each other, but each customer has to opt in to use them. That makes the IBAN the safer choice for business payouts, since every account has one. Collect the recipient's name and IBAN, check the IBAN's length and prefix, and use the account check before the first payment.
How does Due support SAR payouts?
Due pays out SAR to Saudi bank accounts over sarie, per its supported payment methods. Three details apply:
- Rail: payouts run on Sarie Instant, the instant payment system
- Settlement: listed as instant to T+0
- Direction: SAR is payout only, with no SAR pay-in or SAR virtual account
Platforms send SAR through the same API they use for other corridors. MENA-focused Sorbet, for example, uses Due for SAR payouts alongside AED collections and payouts.
