This chapter examines the impact of globalisation and institutional quality on the stability of the GCC banking sector over the period 2022–22. The GMM findings show that globalisation enhances the stability of GCC banks primarily through its economic and social dimensions. Economic globalisation promotes stability through access to international capital markets, whereas social globalisation strengthens resilience via remittances and financial inclusion. Political globalisation contributes to stability only when supported by high regulatory quality. The negative effect of the interaction between globalisation and institutional quality on bank stability may suggest that globalisation strengthens stability when institutions are strong. This chapter recommends further integration into global financial markets, aligning local regulations and governance with global standards and enhancing financial inclusion.
