I did come across the figures for the net interest margin, but in my opinion, the interest paid is really low, compared to the interest received, so I think it's insignificant. And for the NPL, i found the data too, but I don't see a way to analyse them in a meaningful way, and that in my opinion, the loss from npl should be expected loss and therefore priced in the products say charging a higher interest rate for deferred payments.
What do you think
