1. Background
The reported pledging of shares in PT Jhonlin Agro Raya Tbk (JARR) and PT Pradiksi Gunatama Tbk (PGUN) to PT Bank Mandiri (Persero) Tbk has attracted significant public attention. The developments occurred around the reported acquisition by PT Jhonlin Baratama of approximately 30.25% of PT Bayan Resources Tbk (BYAN), valued at around Rp26.1 trillion.
Following the disclosure of the share pledges, JARR and PGUN experienced significant share-price declines. These developments raised questions about financing transparency, collateral risk, banking prudence and investor protection.
Bank Mandiri publicly explained that its financing supported capital expenditure and business needs in coal-related industries, rather than the purchase of shares. The bank also stated that shares were part of a broader collateral package and a secondary source of repayment.
2. Is It Reasonable to Use Publicly Listed Shares as Loan Collateral ?
Yes, provided that the financing is properly structured, transparently disclosed and supported by adequate repayment capacity.
Pledging shares is a recognised financing mechanism. It allows companies or shareholders to obtain credit without immediately selling their investments. However, shares are volatile assets whose market value can decline rapidly, especially during periods of economic uncertainty.
A bank should therefore assess the borrower's operating cash flow, debt-service capacity, financial position and business prospects. Collateral should provide additional protection rather than replace the borrower's ability to repay the loan.
3. Principal Risks
The main risks associated with large share-backed loans include:
a. Market risk: A substantial decline in share prices can reduce collateral coverage.
b. Credit risk: The borrower may be unable to repay principal and interest on schedule.
c. Concentration risk: Large exposures to affiliated companies can increase the bank's vulnerability.
d. Dividend risk: Lower corporate profits may reduce dividends available to support debt repayment.
e. Liquidity risk: Selling a large block of shares during a market downturn may be difficult without a substantial discount.
f. Governance risk: Unclear disclosures or potential changes in corporate control may undermine investor confidence.
g. Systemic risk: Excessive lending based on volatile assets may amplify financial stress if several risks materialise simultaneously.
4. Regulatory and Governance Responsibilities.
Bank Mandiri must ensure that lending decisions comply with applicable banking regulations and internal risk-management standards. OJK should assess credit quality, connected exposures, collateral valuation and the borrower's repayment capacity.
The Indonesia Stock Exchange (IDX/BEI) should ensure that listed companies provide timely and accurate material disclosures. Investors should have sufficient information to evaluate the implications of significant share pledges and potential changes in ownership or control.
A share pledge alone does not establish wrongdoing, default or a regulatory violation. These questions must be assessed using the relevant documents, disclosures and applicable laws.
5. Recommendations
For Bank Mandiri:
- Prioritise sustainable operating cash flow when assessing repayment capacity.
- Apply conservative collateral valuations and appropriate safety margins.
+ Conduct stress tests covering falling coal prices, lower dividends and declining share prices.
- Establish clear procedures for collateral shortfalls and loan defaults.
For OJK and the IDX:
- Strengthen supervision of material share pledges and concentrated credit exposures.
- Ensure consistent application of disclosure and prudential requirements.
- Monitor potential effects on corporate control, market stability and minority shareholders.
For investors and companies:
- Evaluate financial statements, leverage, cash flow and dividend sustainability.
- Avoid relying solely on share-price movements or media speculation.
- Maintain transparent ownership structures and responsible financing practices.
6. Outlook for 2026–2029
Three broad outcomes are possible.
a. Positive scenario: Strong operating performance and adequate cash flow support debt repayment, allowing the financing and acquisition to proceed sustainably.
b. Moderate-risk scenario: Weaker commodity prices or reduced dividends place pressure on debt-service capacity and require tighter financial controls.
c. Negative scenario: Falling share prices, insufficient cash flow and refinancing difficulties create collateral shortfalls, potential forced sales and reduced investor confidence.
These scenarios are conditional possibilities, not predictions. Their likelihood depends on the actual loan structure, borrower finances, market conditions and effectiveness of risk controls.
7. Conclusion
The use of publicly listed shares as collateral for a jumbo bank loan can be commercially reasonable and legally permissible. However, the size of the collateral does not automatically demonstrate that a loan is safe.
In the Haji Isam–Bank Mandiri–Bayan Resources case, the scale and timing of the reported transactions justify careful examination of repayment capacity, collateral valuation, concentration risk and public disclosure. They do not, by themselves, prove misconduct or establish that the pledged shares directly financed the acquisition.
POINT Consultant's central recommendation is that prudent lending must be based primarily on sustainable cash flow, supported by conservative collateral valuation, rigorous stress testing, effective supervision and transparent disclosure.
The ultimate test is whether the borrower can continue servicing its debt even if coal prices, dividends and pledged share prices decline simultaneously.
