Credit Suisse was a global systemically important bank (G-SIB) with operations and legal entities across many jurisdictions. Applying resolution tools, especially bail-in (where creditors' claims are written down), requires smooth cooperation and legal frameworks that are aligned across these jurisdictions. The Credit Suisse case exposed difficulties in achieving this alignment quickly and effectively during a crisis. Effective cross-border resolution requires strong international cooperation and legal harmonization. The Credit Suisse case demonstrated that while progress has been made, gaps remain, especially in the practical execution of cross-border bail-ins.

B is incorrect. While pre-crisis planning is crucial, the Credit Suisse resolution primarily exposed issues with the execution of those plans across borders, not necessarily a lack of focus on planning itself.

C is incorrect. The resolution involved a forced merger facilitated by the Swiss authorities, not a reliance on shareholder equity to absorb losses.

D is incorrect. The Credit Suisse situation was unique due to its size and systemic importance, and the resolution strategy was tailored to that context (a forced merger), not a uniform strategy applied broadly.
