About USD to SAR
The Saudi Central Bank (SAMA) has held the riyal at 3.75 per US dollar since 1986, one of the longest-running pegs in the world.
Because of the peg, any large difference between a quote and 3.75 is the provider’s margin or fee, not a market move.
Saudi Arabia is one of the largest sources of remittances worldwide, so it pays to compare transfer quotes — see the transfer fee calculator.
Assumptions
- The rate is a mid-market reference rate, not a bank’s buy or sell price.
- Rates are published once per working day and cached on your device for up to an hour.
Common mistakes
- Expecting a bank or exchange shop to give you the reference rate exactly.
- Forgetting to check the publication date on weekends and public holidays.
