Preparing for Interest Rate Changes: How Irish SMEs Can Protect Their Borrowing Costs

At Quinlan Accountants we believe that interest rates deserve a permanent place on every SME owner’s agenda, not just a glance when the headlines turn dramatic. After a long period in which borrowing costs seemed to move in only one direction, the environment has shifted again. The European Central Bank raised its key rates in mid 2026, the first increase in several years, driven by renewed inflation pressures, and markets remain divided on where rates go next. For businesses with borrowings, or plans to borrow, this uncertainty is not an abstract economic story. It flows directly into monthly repayments, investment decisions and cash flow. The good news is that interest rate risk is one of the most manageable risks a business faces, provided owners prepare before changes arrive rather than react after them.

The essential first step is knowing exactly what you are exposed to. Many owners are surprised, when they list their facilities, by how much of their borrowing moves with the market.

Understand Your Current Exposure

Start with a simple exercise: list every borrowing in the business, including term loans, overdrafts, asset finance, invoice finance and any property lending, and identify whether each carries a fixed or variable rate. For fixed facilities, note when the fixed period ends, because that is the date your protection expires. For variable facilities, calculate what a one or two percentage point rise would add to annual costs.

This exercise takes an hour and transforms the conversation. Instead of a vague sense that rate rises are unwelcome, the owner knows precisely which facilities are exposed, what the cash flow impact of plausible movements would be and when key decision points arrive. Personal exposure matters too: directors whose personal finances are stretched by mortgage costs may feel pressure on drawings just as the business feels it on borrowings.

Consider Fixing While Choices Remain

The choice between fixed and variable rates is a trade-off between certainty and flexibility. Fixing converts an unknown future cost into a known one, which is particularly valuable for businesses with tight margins or heavy borrowings, where an unexpected rise in repayments would cause genuine strain. Variable rates preserve the benefit of any future falls and usually avoid early repayment complications, but they leave the business carrying the risk.

There is no universally correct answer, and attempting to outguess central banks is not a strategy. The better question is about resilience: if rates rose further, would the business remain comfortable? If the honest answer is no, then certainty has real value, and fixing some or all of the exposure, or splitting facilities between fixed and variable portions, deserves serious consideration. Blended approaches often suit SMEs well, capping the downside while retaining some flexibility.

Reduce the Debt That Costs You Most

Protection is not only about rate structures. It is also about the quantity and quality of debt carried. Periods of rate uncertainty are the right time to review the whole borrowing stack. Expensive, flexible debt such as overdrafts and unstructured short-term facilities are usually the first to feel rate increases, and businesses that lean on them permanently pay dearly for what should be occasional convenience.

Practical steps include converting persistent overdraft reliance into appropriately structured term lending, repaying the dearest facilities first where cash allows, and improving working capital so less borrowing is needed at all. Faster invoicing, tighter credit control and leaner stock levels all reduce the funding gap the business must finance. Every euro of working capital released is a euro that no longer accrues interest at anyone’s rate.

Stress Test Before You Commit

For new borrowing, the discipline is to test affordability under pressure, not under hope. Model repayments at rates meaningfully above today’s, and ask whether the investment still makes sense and the repayments remain comfortable in a weaker trading year. If a project only works at current rates with optimistic sales, it is not a rate rise away from trouble. It is already too fragile.

Lenders apply exactly this thinking when assessing applications, so businesses that arrive with stress-tested forecasts not only protect themselves but present as stronger borrowers, which often translates into better terms.

Stay Close to Your Numbers and Your Advisers

Finally, rate risk management is not a one-off task. Fixed periods end, facilities roll over, plans change and the rate environment evolves. Building a periodic borrowing review into the annual financial calendar, alongside budgeting and tax planning, keeps the business ahead of its decision points instead of discovering them in arrears.

For Irish SMEs in 2026, the return of rate uncertainty is a reminder rather than a crisis: the cost of money moves, and well-run businesses plan for movement. Those that understand their exposure, structure their debt deliberately and stress test their commitments will find that rate changes, whichever direction they take, are events to be managed rather than feared.
