Longer Audit Tenure and Larger Audit Firms Boost Reliability of Bank Financial Reports

Ilusstration by AI

A 2026 study by Nia Afriha and Luke Suciyati Amna from Bandar Lampung University finds that audit tenure, audit firm size, and audit fees play a crucial role in strengthening the integrity of financial statements in the banking sector. The findings highlight the importance of high-quality auditing in maintaining public trust in financial reporting.

Amid ongoing issues of financial reporting violations in Indonesia’s banking industry, including cases involving fictitious loans, the need for transparent and reliable financial statements has become increasingly urgent. Inaccurate reports can mislead investors, regulators, and the public in making economic decisions.

The researchers applied a quantitative approach by examining 23 banks listed on the Indonesia Stock Exchange during the 2022–2024 period. Using data from annual reports, they analyzed 69 firm-year observations through multiple linear regression after passing standard statistical tests.

Key Findings

The study reveals several important insights:

  • Audit tenure has a positive and significant effect on financial statement integrity
  • Audit firm size, particularly large firms (Big Four), shows the strongest influence
  • Audit fees that are proportionate improve the quality and reliability of reports
  • All three variables simultaneously have a significant impact on financial reporting integrity

Statistically, these factors explain 15.6% of the variation in financial statement integrity, with the remainder influenced by other variables not included in the model.

Why These Factors Matter

Nia Afriha explains that an optimal audit duration allows auditors to understand a company’s operations without compromising independence. A tenure that is too short limits insight, while one that is too long may reduce objectivity.

Luke Suciyati Amna emphasizes the importance of large audit firms. According to her, larger firms have stronger resources, better quality control systems, and higher reputational stakes, enabling them to deliver more reliable audits.

Audit fees also play a key role. Adequate fees allow auditors to allocate sufficient time and effort, resulting in more thorough audit procedures and reduced risk of misstatements.

Real-World Implications

The findings carry broad implications:

  • For banks: improved transparency and investor confidence
  • For regulators: evidence to support policies on auditor rotation and audit standards
  • For companies: encouragement to engage reputable auditors with adequate fees
  • For the public: greater assurance of trustworthy financial information

The study also reinforces agency theory, which highlights the importance of external monitoring mechanisms in reducing conflicts of interest between management and shareholders.
