Senior Bank Won't Top Up, Subordinate Working Capital Stack
When your major-bank senior facility is fully drawn, stacking a subordinate cashflow facility behind it can be cleaner than refinancing the senior. Here is what stacks, what breaches, and what a non-bank specialist tier actually looks at first.
Quick Answer
Two routes open up once a senior facility is fully drawn: reprice the whole facility, or sit a subordinate cashflow stack behind it. The second route is often the cleaner one, because a non-bank specialist tier takes second-position security, typically a caveat or registered second mortgage, with a deed of priority to your senior.
Why the senior bank stops short of a top-up
The senior bank rarely says you cannot have more credit. It says it cannot give you more credit, on this facility, at the current settings. The reason is structural, not personal.
Under APRA's APS 220 Credit Risk Management framework, ADIs maintain a credit risk management framework and enforce internal credit controls and limits within board-set risk appetite, covering household, small business and corporate lending. A fully-drawn senior facility has limited policy headroom under that framework. The bank's internal credit controls, not your trading performance, are what closes the top-up door.
That policy boundary is the structural reason additional capacity is structured as a subordinate cashflow stack behind the senior, not a refinance of it. Refinancing means breaking the senior facility and resetting the rate. Stacking leaves the senior intact and adds a second layer.
What stacks cleanly, what triggers a senior covenant breach
The subordinate-facility headroom calc is the first thing that runs. What lenders actually look at first is whether your senior facility's terms permit a second-position security to be registered behind it. Most major-bank business facilities do, with consent. Some do not.
Headroom check, on the senior agreement
The first read is whether the senior facility permits second-position security with consent. A negative pledge clause, a no-consent provision, or a cross-default clause that treats subordinate borrowing as a breach all stop the stack at this step. Where the senior agreement is silent, consent is usually attainable.
Priority deed signature, on the senior bank side
The senior issues the priority deed once total leverage stays inside the senior covenant ratios and the subordinate lender's headroom calc holds with the senior fully drawn. Major banks usually turn the deed inside 5 to 10 business days indicative. The bottleneck is rarely the subordinate lender, it is the senior's internal credit risk sign-off.
Settlement and the 12 to 24 month exit
The subordinate lender settles behind the senior on second-position security. The exit path is defined at settlement, not retrofitted, with a clear route back to a single senior facility inside 12 to 24 months through retained earnings, a property settlement, or a refi-ready submission once the file is filed.
A clean stack carries a deed of priority signed by both lenders. The senior keeps first-call on proceeds. The subordinate sits behind it. The borrower's total leverage rises, but the senior's position is protected, which is what the deed of priority is for.
How the deed of priority and second-position security actually fit
Second-position security, typically a caveat or registered second mortgage, is what gives the subordinate lender its claim on proceeds after the senior is paid. The deed of priority then locks the order of repayment in writing.
The deed-of-priority signature window is approximately 5 to 10 business days indicative, depending on which bank holds the senior. Major banks usually have a standing template and a panel solicitor who turns it round inside a week. Some tier-2 specialists take longer because the wording goes through their credit risk team.
From the practitioner side, the bottleneck is rarely the subordinate lender. The bottleneck is typically the senior bank's internal sign-off on the priority deed. Where speed matters more than pricing, a caveat loan can hold the cashflow position while the priority deed is being signed in the background.
Reading the file the way the subordinate lender reads it
The non-bank specialist tier that writes subordinate cashflow facilities reads three things first: the senior covenant test, the subordinate-facility headroom calc, and the exit.
The senior covenant test asks one question: does taking this second facility breach any ratio, negative pledge or cross-default clause in the senior agreement? If it does, the file stops. If it does not, the subordinate lender moves to headroom.
The headroom calc is conservative. It assumes the senior stays fully drawn. It does not assume the senior gets repaid out of the subordinate facility. Most non-bank specialist tier writers cap total leverage at a level that leaves the senior unbroken even in a downside.
The exit is what closes the file. Subordinate cashflow facilities are not designed to live forever. The lender wants a clear path back to a single senior position within 12 to 24 months. That can be retained earnings, a property settlement, or a clean refi-ready submission once EOFY 30 June 2026 numbers are filed.

A subordinate cashflow stack behind a maxed senior facility is a structural answer to a structural problem. The senior bank is not refusing because of trading performance, it is constrained by its own credit risk framework. The non-bank specialist tier sits behind it with second-position security and a deed of priority, leaving the senior's pricing and terms intact while you carry the next 60 to 90 days of cashflow.
Key takeaway: when the senior says no top-up, stack behind it, do not refinance it.Frequently Asked Questions
A subordinated business loan is a facility that sits behind a senior lender's first-position security, with a deed of priority governing the order of repayment. The senior lender keeps first-call on proceeds in a default scenario, and the subordinate lender accepts second-call in return for risk-adjusted pricing.
It is one of the standard tools in a working capital capital stack when the senior facility is fully drawn but the trading position is otherwise sound.
Yes, in most cases you can take a second business loan when your bank says no to a top-up, provided your senior facility permits a second-position security and the non-bank specialist tier lender writing it can complete a subordinate-facility headroom calc that holds. The senior bank says no to top-ups not because trading is weak, but because its internal credit controls have limited headroom on that facility.
A subordinate cashflow stack works around that boundary without breaking the senior. For the property-owner view of when a second mortgage is the right answer, see our property-backed working capital red and green flags.
A deed of priority is a written agreement between two lenders that locks in the order of repayment in a default. The senior lender retains first-call on proceeds, and the subordinate lender accepts second-call after the senior is paid out.
Without a signed deed of priority, most subordinate lenders will not fund a caveat or registered second mortgage behind an existing senior facility. The deed is what makes the subordinate position bankable.
Whether a subordinate facility triggers your senior covenant depends on how the senior agreement is drafted. Most major-bank business facilities permit a second-position security with consent, and the consent is granted through the deed of priority process.
Some carry a negative pledge or cross-default clause that would treat the new borrowing as a breach, in which case the stack is not workable and a refinance becomes the lane instead. The senior covenant test is the first check, not the last.
A subordinate working capital facility typically settles inside the deed-of-priority signature window, which is approximately 5 to 10 business days indicative once the senior bank engages. The subordinate lender can usually move inside 48 to 72 hours on the credit decision. The bottleneck is the senior bank's panel solicitor on the priority deed.
For a faster-clearing option where the senior cannot move, a caveat loan sometimes bridges that gap. See how cashflow facilities stack for the broader sequencing logic.
