The borrowing company defrauded the bank loan, does the guarantee company still need to compensate the loan?

You can go to court. Although the enterprise made a secured loan, due to the unclear due diligence of the bank, the bank first neglected its duty and suspected that the bank account manager colluded with the enterprise, thus defrauding the bank.

If it is normal, loans overdue must pay compensation, but if the information provided by the enterprise is untrue and the bank has obvious mistakes, it must rely on the law to protect itself.
