Point of Non-Viability (PONV)
The Point of Non-Viability is the trigger at which the RBI can require a bank's AT1 and certain Tier 2 instruments to be written down or converted to equity to keep it afloat.
PONV is a Basel III concept: if the regulator judges a bank non-viable without support, the bank's loss-absorbing capital instruments must take losses before any public money is used. This is what allows AT1 bonds to count as going-concern capital.
In India, the PONV clause was invoked in the Yes Bank reconstruction, where AT1 bonds were fully written down. PONV is the reason AT1 and similar instruments carry higher risk and yield than ordinary bank bonds, since holders can be wiped out at the RBI's discretion.
