Using Shares and Investment Portfolios as Business-Finance Collateral
Eligible shares or investment holdings may support specialised finance, but market volatility, portfolio concentration, custody, regulatory status, margin calls and forced-sale rights make this materially different from property or equipment-backed lending.
General commercial information only—not financial-product advice. Margin lending facilities are regulated financial products. Availability must be confirmed with an appropriately authorised provider and is subject to assessment, documentation and product rules. Securities may be sold following a margin call or default.
A portfolio’s market value is not the same as borrowing capacity. The provider may exclude securities, apply different margins, cap concentration, control custody and revalue the collateral continuously. A fall in value can create an urgent obligation to add cash, provide more collateral or reduce the loan.
What is share-backed business finance?
Share-backed business finance is a specialised facility supported by eligible securities or investment holdings. Depending on its legal and product features, it may be a margin lending facility or another securities-backed arrangement.
The borrower may seek funds for a genuine business use without immediately selling the investments. This does not remove investment risk. The borrower continues to face changes in portfolio value while also carrying finance costs and repayment obligations.
Important boundary: this guide does not state that Basic Finance Loans or every lender provides share-backed facilities. Product availability, authorisation and suitability must be confirmed before proceeding.
Margin lending requires appropriate authorisation
ASIC states that a margin lending facility is a financial product under the Corporations Act. Issuers and advisers of margin lending facilities must hold an Australian financial services licence with the relevant authorisation and comply with applicable licensing, conduct and disclosure requirements.
Provider authorisation
Confirm that the entity issuing or advising on the facility holds the appropriate authorisation or operates under a valid arrangement.
Product disclosure
Read the relevant facility documents, disclosure material, approved-securities rules, margin policy and enforcement provisions.
Advice boundary
General loan information is not a recommendation to retain, sell, buy or leverage any particular financial product.
Margin-call responsibility
Understand who gives notices, how quickly the borrower must respond and what happens if contact cannot be made.
Legal classification depends on the actual facility and parties, not its marketing label. Obtain appropriately licensed financial-product advice and legal, tax and accounting advice where required.
Which investment holdings may be considered?
Listed Australian shares
Eligibility may depend on market liquidity, price history, market capitalisation, volatility and the provider’s approved-securities list.
Exchange-traded funds
A diversified exchange-traded holding may be assessed differently from a concentrated single-company position.
Managed investments
Units may involve redemption rules, liquidity limits, valuation timing and issuer-specific eligibility requirements.
Bonds and other instruments
Credit quality, maturity, trading liquidity, price transparency and custody can affect acceptability.
The provider may reject otherwise valuable holdings. Suspended securities, restricted stock, thinly traded companies, derivatives, highly concentrated positions or instruments with uncertain ownership or transferability may be ineligible or heavily discounted.
Portfolio value does not equal available cash
Each eligible holding may receive its own accepted margin. The provider may also impose portfolio-wide concentration limits and buffers. Existing margin debt and transaction costs reduce net availability.
Indicative usable value = sum of each eligible holding’s accepted market value × its approved margin − existing secured debt − required buffers − retained interest − establishment, legal and other approved costs.
This is a conceptual framework only, not a quoted formula or lending parameter. Market prices and provider rules can change. A security accepted today may later receive a lower margin, become restricted or cease to be eligible under the documents.
Market value
The current quoted value can move during the day and may not represent proceeds achievable for a large or illiquid parcel.
Approved margin
The provider determines what proportion of an eligible security’s value contributes to borrowing capacity.
Concentration limit
A large exposure to one company, sector or related group may be capped or discounted.
Net settlement funds
Available business capital is the remainder after debt, buffers, interest and approved transaction deductions.
Falling markets can turn equity into an urgent obligation
A facility may monitor the relationship between the loan balance and accepted collateral value. If the portfolio falls or the loan grows beyond the agreed threshold, the borrower may receive a margin call.
Add cash
The borrower may need to reduce the outstanding balance within the time allowed by the facility.
Add eligible collateral
Additional approved securities may restore the required buffer, subject to acceptance and custody rules.
Sell investments
The borrower may sell holdings and apply proceeds to the facility, potentially realising losses or tax consequences.
Provider sale
If the call is not met, the provider may sell securities under the documents—potentially without waiting for the borrower’s preferred timing.
Market movements can be rapid. The portfolio may be sold into a falling market and the borrower can remain liable if net proceeds do not clear the debt. A business should not assume that future dividends, a market rebound or an uncommitted refinance will solve a margin call.
Model the downside before borrowing
- fall in the value of the largest holding;
- simultaneous decline across a sector or market;
- suspension, delisting or reduced liquidity;
- lower provider margin or removal from an approved list;
- interest capitalisation or increased facility balance;
- short margin-call response period;
- inability to transfer or pledge additional securities;
- forced sale creating a tax liability or crystallised loss;
- business cash flow weakening at the same time as markets; and
- sale proceeds failing to repay the full facility.
Liquidity must exist outside the portfolio. A prudent contingency plan identifies cash or other readily available resources that could meet a call without relying on the same falling assets.
Confirm how the securities are held and secured
Shares may be held directly, through CHESS sponsorship, through a broker or custodian, or within another legal structure. The provider may require control arrangements, transfer of sponsorship, a security agreement, account restrictions or custody with a nominated intermediary.
The PPSR includes financial-property collateral classes. Official guidance identifies shares, bonds and related products as investment instruments, while rights held through a securities account may be an intermediated security. The correct legal description and perfection method depend on how the asset is held and the facility structure.
Legal owner
Verify the name on holding statements and whether the borrower, trustee, company or another entity owns the collateral.
Existing interests
Identify margin facilities, broker liens, custody rights, All-PAAP registrations or other security claims.
Transfer restrictions
Escrow, shareholder agreements, trust terms, employee plans or foreign-market rules may limit transfer or enforcement.
Control and sale rights
Understand who may trade, substitute, withdraw, vote, receive distributions or sell the securities during the facility.
PPSR registration is not proof of ownership. Securities law, PPSA priority, trust and custody arrangements require legal review.
What may be reviewed?
- borrower and beneficial-owner identity;
- genuine business purpose and required net funds;
- complete portfolio and holding statements;
- security eligibility, liquidity and volatility;
- single-stock, sector and issuer concentration;
- custody, CHESS, broker and account arrangements;
- existing margin loans, liens and PPSR registrations;
- business financial position and repayment capacity;
- interest treatment and total facility costs;
- margin policy, notice method and response times;
- forced-sale, substitution and withdrawal rights; and
- base-case and severe-downside repayment plans.
Prepare before approaching an authorised provider
Define the commercial requirement
State the specific business use, timing and minimum net funds required.
Build the portfolio schedule
List every security, quantity, owner, account, market and any transfer restriction.
Confirm authorisation
Establish that the issuer and any adviser have the appropriate regulatory authorisation for the facility and service.
Review eligibility and custody
Determine accepted holdings, margins, concentration rules, control and security documentation.
Calculate net funds
Deduct existing debt, buffers, interest and approved costs from potential availability.
Stress-test and document the exit
Model rapid market falls and identify how calls, serviceability and final repayment would be managed.
A strong portfolio can still produce a fragile structure
A company shareholder holds a listed portfolio and seeks business working capital. The portfolio appears valuable, but most of its value is concentrated in one issuer. A provider may discount that holding, impose a concentration cap and require custody and margin-call rights. The resulting net availability may be materially below the headline market value.
If the major holding falls at the same time as the business needs cash, the borrower could face both operating pressure and a margin call. The structure therefore requires independent liquidity and a repayment plan that does not depend on a market recovery.
Hypothetical example only; not a completed transaction, offer, approval, product recommendation or indication of available terms.

Share-backed finance questions
Can shares be used as collateral for business finance?
Some appropriately structured facilities may accept eligible securities. Product availability, provider authorisation, portfolio eligibility, custody, security and repayment requirements must be confirmed.
Is share-backed finance the same as margin lending?
Not always, but a facility may meet the legal definition of margin lending depending on its features. Legal classification and the provider’s authorisation should be checked.
What is a margin call?
It is a requirement to restore the facility to its agreed collateral position, potentially by adding cash, adding eligible securities or reducing debt. If it is not met, the provider may sell investments under the documents.
Can a lender accept every listed share?
No. Providers may maintain approved lists, apply different margins and impose liquidity, volatility and concentration limits.
Can private-company shares secure a loan?
Potentially in highly specialised circumstances, but valuation uncertainty, transfer restrictions, minority rights and illiquidity can materially limit acceptability.
Can the borrower lose more than the portfolio value?
Yes. If securities are sold and net proceeds do not clear the facility and costs, the borrower or guarantors may remain liable for a shortfall under the documents.
Official resources
Have a complex business funding requirement?
Provide the commercial purpose, required net funds, borrower details, existing obligations and proposed repayment plan. Basic Finance Loans can discuss whether a commercial referral pathway may exist, without providing financial-product advice and subject to appropriate provider authorisation and assessment.
Discuss the business requirement
