Fixed vs Variable: A Fresh Look at Interest Rate Strategy

Fixed vs Variable: A Fresh Look at Interest Rate Strategy – April 2025

There’s a lot of noise at the moment around where interest rates are headed. Many of our clients at Sprout Ag are currently locked into fixed rates, and the question of whether to break those rates – or stay the course – is coming up more and more.

A while back, we wrote about the pros and cons of fixing your interest rates. That advice still stands, but we thought it was timely to add some updated commentary, particularly with the uncertainty we’re seeing across the market now.

At Sprout Ag, we tender between $500–800 million in farm debt every year. Analysing the cost of debt is something we live and breathe – it’s part of our day-to-day work, and risk management conversations with our clients are ongoing.

The reality is: no one really knows where interest rates are going. This has been proven time and time again. Right now, there’s a lot of chatter about tariffs and their broader impacts. If tariffs continue to unfold in the current direction, the simple likelihood is that they will be deflationary for Australia, which would put downward pressure on interest rates.

In the meantime, we’re receiving increased enquiries from farming businesses asking about breaking their current fixed rates and shifting to variable. At the same time, banks are actively promoting new fixed-rate products. It’s a fascinating dynamic and one we’re keeping a close eye on.

We’re also seeing a significant difference in interest rates depending on whether a client is on a bank’s reference rate or a market-based rate (priced off BBSW or BBSY). These nuances make it even more important to assess each business’s situation individually rather than adopting a ‘one-size-fits-all’ approach.

A quick refresh on the pros and cons of fixing vs variable:

Pros of Fixed Rates:

  • Certainty of repayments for the fixed term.
  • Protection if interest rates rise sharply.
  • Helpful for budgeting and cash flow forecasting.

Cons of Fixed Rates:

  • Less flexibility (break costs can be significant if you want to pay off debt early or refinance).
  • You could miss out if rates fall.
  • Limited ability to restructure debt during the fixed term.

Pros of Variable Rates:

  • Flexibility to pay down debt faster without penalty.
  • Ability to take advantage of falling interest rates.
  • Easier to refinance or restructure if opportunities arise.

Cons of Variable Rates:

  • Exposure to rising interest rates.
  • Less certainty for budgeting purposes.

Our personal view?

Variable interest rates generally offer greater flexibility. In our experience, fixed rates have rarely delivered a major benefit for clients, except in the case of locking in at the ultra-low rates we saw a few years ago.

In summary:

Choosing between fixed and variable rates should always come down to your business’s circumstances, cashflow strategy, and risk appetite. There’s no blanket answer, but the important thing is to make an informed decision, with a clear understanding of both the risks and the opportunities.

Why Scale Matters More Than Ever in 2025

In today’s economic climate, the ability to scale—spreading a greater amount of revenue over your fixed costs—has never been more critical for Australian businesses.

Fixed costs such as wages, insurance, interest rates, and electricity have surged by over 30% in recent years, with variable and input costs also rising significantly. While some strategies can help reduce these expenses—such as using Sprout Ag’s bank tender service to secure lower interest rates—the reality is that most fixed costs are here to stay.

One of the most effective ways to navigate these rising costs is to focus on increasing revenue and production, allowing your business to spread those expenses across a larger income base.

The Power of Scale

At Sprout Ag, we’re seeing a clear trend—clients who operate at scale, whether through higher production volumes or greater revenue in a single commodity, are less vulnerable to rising costs.

Scaling up doesn’t always mean increasing expenses. In many cases, growing revenue doesn’t necessarily require additional machinery, higher accounting fees, or increased insurance costs. With the right planning, many businesses can grow revenue by 20% or more without significantly expanding their overheads.

Staying small and simply watching expenses is unlikely to be a sustainable long-term strategy. Instead, as turnover and production become critical to business success, ensuring revenue growth exceeds fixed costs is key to profitability.

Building Scale Into Your Business: Key Considerations

  • Shift Your Mindset – Fixed costs are unlikely to return to where they were four or five years ago, so adjusting your business strategy accordingly is essential.
  • Plan for Growth – Set time aside to explore different revenue growth strategies and how they can be spread across existing fixed costs.
  • Focus on Sales, Not Expenses – Identify ways to boost sales without proportionally increasing costs. Businesses with a variable cost structure often have the advantage here.
  • Review Overhead Usage – Assess whether your current overheads are still serving your business effectively, and consider reallocating capital to more productive areas such as equipment.
  • Leverage Workforce Capacity – Explore whether there’s additional capacity within your family farm workforce to support business expansion.
