USD/SAR is a currency pair that shows the exchange rate between the base currency and the quote currency in the global forex market.

Key factors include central bank interest rate decisions, economic data such as GDP, inflation, and employment, and geopolitical events.

The spread is the difference between the bid and ask prices. Major pairs typically have tighter spreads due to higher liquidity.

Highest liquidity and tightest spreads are typically during the London-New York session overlap (13:00–17:00 UTC).

Carry trade involves borrowing in a low-interest-rate currency and investing in a higher-interest-rate currency to profit from the rate differential.
