What are the chances of getting money back from YES Bank investments in AT1 BONDS sold to meas super FD.I am a retired citizen.

To be frank, the chances are almost nil. Normally, once the AT1 bonds are written off in the balance sheet, it is rarely paid back because it is that kind of risk capital. It is unfortunate that the bank sold these bonds to you as Super FDs, but I would suggest that you should talk to your financial advisor on this matter.

Typically, these AT1 bonds are like equity as they are perpetual in nature. They only carry interest and in the case of Yes Bank, the other banks agreed to take a stake in Yes Bank only if these AT1 bonds were repudiated. There was really no choice for the investors in this case. If you get back any money, it is just a bonus.
