Though I feel that I am missing something, I think if you are right and RE invokes DLG at first loss they face any portfolio then there would be no benefit of becoming DSA as you might be aware these are high interest loan (than bank) and somewhat questionable credit - all that backed in interest loan so RE is expecting some loans to go NPA and my believe that DLG will be invoked once that limit is breached as RE will hold digital DSA for giving bad clients. please feel free to correct me.
Thanks!
