50 Riyals Saudi Central Bank

The 2021 series marked SAMA's rebranding from "Saudi Arabian Monetary Authority" — the name the institution had carried since its 1952 founding — to "Saudi Central Bank," a shift reflecting a broader GCC trend toward aligning central bank nomenclature with international norms. The change required a full series redesign rather than an overprint, which is why P#48 exists as a distinct issue rather than a minor variant of the preceding family.

De La Rue's retention as printer is unremarkable given their decades-long relationship with Saudi Arabia, but the security specification here is notably lean for a mid-denomination note of this period — watermark and thread only, without the optically variable elements increasingly standard on comparable issues from neighboring central banks.
