On a final note, Republic Act No. 8971, or the General Banking Law of 2000, recognizes the vital role of banks in providing an environment conducive to the sustained development of the national economy and the fiduciary nature of banking; thus, the law requires banks to have high standards of integrity and performance. The fiduciary nature of banking requires banks to assume a degree of diligence higher than that of a good father of a family.[39] In the case at bar, petitioner itself was negligent in the conduct of its business when it extended unsecured loans to the debtors. Worse, it was in serious breach of its duty as the trustee of the MTI. It was not able to protect the interests of the parties and was even instrumental in violating the terms of the MTI, to the detriment of the parties thereto. Thus, petitioner has only itself to blame for being left with insufficient recourse against petitioner under the assailed MTI.
