Both the auditing standards, Indian as well as International Accounting standards have compliment each other. The problem is not the option of standard of auditing but the methods adopted by the Auditors themselves.
I worked for more than 12 years in Finance department of International Bank in Saudi Arabia, Bermuda, India and Dubai. There is always a window dressing done prior to the closing of the banks. The adjustment is always done in " Adjustment account, accrual account and loan loss and operational loss provisions.
Most of the financial audititors conduct only the reconciliation of accounts and reconciliation of balances with the source. In most cases, when the profit is in excess of forecast/guidance, either provision is made or write back to the Profit.
IAS 39, IFRS as well as Indian audit standards are all the same but the application of these standards are most of the times flouted by the auditing firm at partners level in connivance with the Boards or CEO of the Bank.
CEO of Lehman Bros few days before the bankruptcy petition claimed that the financial of the bank is sound and he quoted the interim auditors' statement. Same as the case for ENROL, Worldtel. In 2010, 32 banks in USA were closed due to non compliance with the prudential norms.
Therefore, I am of the opinion that standards are fine but the application by the Auditing firms need to be closely monitored.
I suggest that one of the best way to monitor the auditors work is audit by Central Bank based on exceptions, though it sometimes is difficult
