Not all banks price their commercial loans the same way, and understanding the mechanics behind your interest rate is crucial for your business’s bottom line.
When securing a commercial loan, it is easy to fixate on the headline interest rate. It is the most visible number on the term sheet, after all. However, unlike standard residential mortgages, commercial lending is a complex beast where the “cheapest” rate today doesn’t always guarantee the lowest cost tomorrow.
To truly optimise your lending structure, you need to understand what components make up your rate, how market sentiment drives pricing, and why the structure of your loan often matters more than the percentage point itself.
Decoding the Jargon: What is BBSY?
If you have reviewed a commercial loan contract recently, you likely encountered the acronym BBSY (Bank Bill Swap Bid Rate). While it sounds technical, the concept is straightforward.
In essence, BBSY is the rate at which banks buy and sell money to each other on the short-term market.
The key phrase here is short-term. While you receive your cash at settlement, behind the scenes, your loan is often in a state of constant flux, being “repriced” at selected intervals. You might see terms like “30-day rolls,” “90-day pricing,” or “180-day bills.”
Think of these as mini fixed-rate periods. If you select a 30-day roll:
- Your rate is set for 30 days.
- At the end of that period, your loan is repriced against the current market.
- If the 30-day price has risen, your rate goes up for the next month. If it drops, you benefit immediately.
The Trade-Off: Flexibility vs. Certainty
Once you understand that your rate is moving, the question becomes: how often do you want it to move? The choice generally falls between short-term rolls (variable) and longer-term fixed rates.
Short-Term Rolls (30–90 Days)
This option is often about playing the market as it stands right now.
- The Upside: These are generally priced very close to real market rates because banks don’t have to price in long-term risk. They are often the “cheapest” option on paper and offer great flexibility, allowing you to draw down or pay back portions of the loan at each rollover date.
- The Downside: They are volatile. Your repayments can vary significantly from month to month, providing less certainty for cash flow forecasting.
Fixed Market Rates (1–5 Years)
This option is for those who value stability over rock-bottom pricing.
- The Upside: You gain absolute clarity on your repayments with a “set and forget” mentality.
- The Downside: You pay for that certainty. Fixed rates can be more expensive, especially in a rising market, and they lack flexibility. You will likely face break costs if you try to pay the loan out early, and you generally cannot utilise stepped drawdown periods.
A Note on “Term”: Even if you agree to a loan term of 3+ years, remember that most commercial lenders will still conduct annual reviews. They may request updated financials to ensure your business condition hasn’t changed, allowing them to mitigate risk before you get into trouble.
The Hidden Driver: RBA vs. BBSY Pricing
One of the most critical distinctions in commercial lending is whether your bank prices its loans based on the RBA Cash Rate or the BBSY.
Let’s look at a hypothetical scenario. You have run a tender and narrowed it down to two options:
- Bank A: Offering 5.89% (Priced on RBA Rate + Margin)
- Bank B: Offering 6.04% (Priced on BBSY + Margin)
On the surface, Bank A looks like the winner. But is it?
Bank A (RBA Linked): The RBA rate is static until the Reserve Bank board meets. If the market expects a rate rise next week and the RBA pulls the trigger, your 5.89% could immediately jump to 6.14%.
Bank B (BBSY Linked): The BBSY is market-driven. If economists predict a rate rise, the BBSY often moves before the RBA announcement. In this scenario, the 6.04% rate likely already includes the “priced in” market expectation. When the RBA actually raises rates, your Bank B loan might not move as drastically because the market had already accounted for it.
In an environment where rates are predicted to rise, variable market rates (BBSY) often move based on sentiment before the official decision is made.
The Verdict: Cheapest Is Not Always Best
Choosing the right commercial loan isn’t just about picking the lowest number. It requires a holistic view of your business’s cash flow, the asset being funded, and your personal outlook on the economy.
If you are funding a long-term asset with stable cash flow, certainty might be worth a slightly higher premium. If you need liquidity and plan to pay down debt aggressively, a flexible short-term roll structure might be superior despite the volatility.
Next Steps
Commercial lending structure and flexibility often mean more than the headline rate. To ensure your debt structure aligns with your business strategy, we recommend having a detailed discussion with your advisor about where rates are heading and how different pricing models will impact your specific situation.
