Fig. 6

Unconditional variation of CIR and ROA across bank size groups. Note: box plots for pooled sample period 2010–2019. Boxes show 25th, 50th and 75th percentile; whiskers show 10th and 90th percentile. Size quintiles for non-SIBs and wealth management (WM) banks are defined by year. In panel B, only quintiles 3–5 are shown because smaller wealth management banks exhibit even higher variation in CIR and ROA
