Who exactly is responsible for the whole PNB-Nirav Modi fiasco? Is it Nirav Modi himself, whose diamond trading firms used irregular LoUs to get money from foreign branches of Indian banks, without paying the required collateral? Is it the diamond trading firms but not Modi? The PNB officials who issued the LoUs and operated them outside the bank’s proper framework? PNB itself?
The CBI will no doubt investigate the role played by each of these parties, among whom the fault for the scam will lie in varying degrees. The headlines will of course belong to the allegations of fraud and the anger that Modi has been able to leave the country and get away. However, this kind of thing will keep happening unless we understand the institutional failures that made it possible.
PNB’s failure to detect the fraud is obviously one, and the bank is having to agree to pay astronomical sums of money to the foreign branches of Indian banks who aren’t getting their money back from Modi’s firms.
But what about those foreign banks themselves? Should they have been able to detect that these LoUs were wrongly issued? Can the PNB claim that they don’t have to pay back the full amounts requested by these foreign branches?
