Over the past few years, rates have risen quickly, and for many farm businesses, interest costs have followed. With talk of rates holding or rising more, the impact of these increases are being felt in cash flow and working capital.

Interest costs are often one of the top three expenses in a farming business. And unlike fuel or fertiliser, they are also one of the few costs you can sometimes do something about.

What we often see is farm businesses working incredibly hard on production, efficiency, and margins, yet their interest rate quietly ticks along in the background, unchecked and unquestioned.

So why do interest rates deserve more attention, and what should you actually understand about your own?

Why interest rates are such a hot topic

Interest rates affect more than just your repayment amount.

They influence:

• Cash flow pressure through the season
• How much flexibility your business has in tougher years
• Your ability to fund opportunities like land, machinery, or succession
• How your bank views risk in your business

When rates move, or when your margin is out of step with the market, the impact can compound quickly. A small difference in percentage terms can mean tens of thousands of dollars a year for a medium to large farm business.

That is why, even in busy seasons, interest rates are worth revisiting.

What is an interest rate?

At its simplest, an interest rate is the cost of borrowing money.

But the rate you pay is usually made up of several parts:

• A base rate set by the lender
• A margin that reflects how the bank views your business
• Adjustments for loan type, security, and structure

You do not need to be an expert in this, but having a basic understanding helps you ask better questions and recognise when something does not feel right.

Different banks also calculate and apply rates differently. Fixed, variable, blended facilities, and multiple loan splits can all sit under the one business. This is where it often becomes hard to compare apples with apples.

Base rate vs margin, what actually changes

One of the most important things to understand is the difference between the lender’s base rate and your customer margin. The base rate is the part that moves with the market. It rises and falls as wholesale funding costs change and as the Reserve Bank adjusts the cash rate.

Your margin is the extra percentage the bank adds on top (or in some cases take away), based on how they assess your business and the overall lending risk. This is the part that is more personal, and more negotiable.

When rates rise, many businesses assume the whole increase is unavoidable. But often the base rate moves up, and the margin stays higher than it should, simply because it has not been reviewed in years. That is why it is useful to know what portion of your rate is market driven, and what portion is bank pricing specific to you.

In practical terms, the base rate can move without warning, but the margin should be justified. If your business has improved, your structure is stronger, or your equity position has increased, your margin should reflect that.

Fixed vs variable rates, and why they behave differently

Another layer of complexity is whether your lending is fixed or variable. Variable rates tend to move up and down more quickly as the market changes, and they are usually linked to the lender’s current pricing and funding costs. That means they can rise fast when rates increase, but they can also reduce faster when conditions ease.

Fixed rates work differently. They are typically set based on longer term market expectations, not just today’s cash rate. This is why fixed rates can sometimes be higher than variable, even when people expect rates to fall, and sometimes lower than variable when markets believe rates will rise further.

For many farm businesses, a mix of fixed and variable can make sense, depending on cash flow needs, risk tolerance, and how much certainty you want in your repayments. The key is understanding what you are trying to protect, stability in repayments, flexibility in structure, or the ability to reduce costs quickly if the market improves.

It is also important to remember that fixed rates can limit flexibility. Changes like restructuring facilities, selling security, or refinancing can be more complicated or costly during a fixed term. So the best option is not always the lowest rate, it is the structure that gives you the right balance of certainty and control.

Why comparing your rate with a mate’s can be misleading

We often hear, “My neighbour is paying less than me”.

The challenge is that no two farm businesses are the same.

Your interest rate is influenced by:

• Equity position
• Trading history and volatility
• Security type and location
• Overall loan structure
• How your story is presented to the bank

Without knowing the full financial position behind someone else’s rate, comparisons can be misleading and frustrating.

For our clients, we can compare your position against the broader market and lender expectations. That gives a much clearer view of whether your rate is where it should be.

When your interest rate isn’t where it should be

In our experience, when an interest rate drifts higher than it should, it is usually for one of two reasons.

1. The bank is stuck in the past

Tough seasons happen. Sometimes banks become overly focused on historical performance rather than where the business is heading. Even when margins are improving and plans are solid, old perceptions can linger in pricing decisions.

Unless someone challenges that narrative and clearly explains the future, the rate often does not adjust on its own.

2. Complacency

Sometimes banks simply do not lower rates because no one asks. Loyalty, while valuable in relationships, does not automatically translate to sharper pricing.

This does not mean you need to change banks. But it does mean your rate should be reviewed and justified from time to time.

What is forecast for the rest of the year?

We are not interest rate forecasters or experts. However, based on current commentary from major banks and economists, the expectation is that rates are likely to remain steady in the near term, with potential increases also in discussion.

What matters more than the exact timing is this:

• Your current margin still matters, regardless of where the cash rate goes
• Waiting for cuts does not fix an uncompetitive rate today
• Being well structured puts you in a stronger position when conditions do change

In other words, even in a holding pattern, it pays to make sure your business is not carrying unnecessary interest costs.

A final thought

Interest rates might not be exciting, but they are powerful.

They quietly shape cash flow, resilience, and opportunity in your business. And they deserve the same level of attention you give to other major inputs.
