Among the group, Grupo Financiero Citibanamex SA de CV recorded the biggest drop in its RORWA, falling 135 basis points to 3.55% in the quarter.

In contrast, Grupo Financiero Galicia SA's RORWA jumped 652 basis points to 11.71%, the largest return among the sample. The bank's profit for the third quarter soared 175%.

Meanwhile, Chile's Banco BICE had the smallest RORWA at 0.54%.
