10 Riyals

Qatar's 2020 polymer-hybrid series was among the first significant redesigns since the Central Bank's 2008 family, and the choice to use a hybrid substrate rather than full polymer reflected a regional preference — Gulf states have been cautious adopters of polymer, partly due to documented performance issues in prolonged high-heat environments. De La Rue's hybrid product attempts to split the difference: improved security over pure paper, without the heat-warping complaints that dogged some fully polymer issues elsewhere.

The TBB reference places this within a series that rolled out across denominations between 2020 and 2022, a window that overlapped with the FIFA World Cup preparation cycle and the easing of the Qatar diplomatic blockade that had run from 2017 to 2021.
