Mr Kapoor was arrested and formally charged on March 8th with money laundering and corruption, which he denies.
He becomes merely the latest among once-prominent Indian financiers to find themselves in the hands of the law.
As the bank's customers lined up in the streets to withdraw money from ATMs,
others found their electronic payments disrupted, a consequence of Yes's pivotal role in India's digital-payments architecture.
The finance minister, Nirmala Sitharaman, sought to allay depositors' fears

While the technical issues were swiftly sorted out, fundamental ones remain.
The resolution plan was far short of the $4bn needed for provisioning, reckons Ashish Gupta, an analyst at Credit Suisse, a bank.
SBI has said it does not intend to merge with Yes, leaving the latter's fate unclear and,
to use Mr Gupta's careful phrasing, its "reconstruction…unlikely".

Yet falling stock-markets and financial mayhem make it an inopportune time for dealmaking.
Many of the former optimists of Indian finance who bought into Mr Kapoor's story may never say yes so eagerly again.
