Your debt is more expensive than you planned. Now what?

Bank of America just reversed its 2026 forecast. Three 25-basis-point Fed rate hikes are now projected for September, October, and December, lifting the benchmark to 4.25-4.5% by year-end. Fed Chair Warsh's hawkish stance and core PCE inflation trending toward 3.5% are driving the call.

Markets reacted immediately. Nasdaq fell 2.2%. Treasury yields surged. And corporate finance teams that spent early 2026 planning for a lower-rate world are now doing math they did not expect to do.

The pressure extends well beyond the U.S. The European Central Bank (ECB) hiked rates again in June, its first increase since 2023, after inflation climbed back above 3%. The Bank of England held rates at 3.75% in June, even as UK inflation climbs toward 3.25% by year-end. In Brazil, the Selic rate sits at 14.5%. A geopolitical conflict in the Middle East continues to disrupt energy supply chains, oil prices are volatile, and the price pressures many finance teams assumed were gone are back.

Finance leaders are feeling the squeeze. According to Kyriba's latest Risk Radar survey, 67% of finance leaders globally are concerned about the potential negative impact of interest rates on their business's financial health over the next 12 months. In Mexico, that concern rises to 82%, the highest of any country surveyed.

The hard truth? Most corporate debt portfolios were not built for the current environment. And many treasury teams are still managing their rate exposure through spreadsheets and gut instinct.

That needs to change.

How interest rate risk shows up directly in your financials

Interest rate risk is not just something economists worry about. It shows up directly in your company's numbers.

If you have floating-rate debt exposure (revolving credit lines, variable-rate term loans), every time benchmark rates rise, your borrowing costs go up automatically. No renegotiation needed. It just happens.

Here is a simple example: a company with $500 million in floating-rate debt and a 1% rate increase pays $5 million more in interest expense per year. That is money that does not go to hiring, investment, or shareholder returns. It disappears into financing costs, and the CFO notices.

Floating vs. fixed-rate debt: how to choose your exposure

Most treasurers know they should have a mix of floating and fixed-rate debt. But deciding the right balance is where things get complicated, and where many companies rely more on habit than strategy.

A few things should drive that decision:

• Your business model. If your revenues tend to rise when the economy is hot (and rates are high), floating debt can work as a natural offset. When business is good, you can absorb the cost. When rates fall, so does your bill.

• When you need to refinance. Debt maturing in 18 months has a very different risk profile than a 10-year bond. Timing matters enormously.

• Your covenant headroom. Higher interest costs reduce EBITDA coverage ratios. If you are close to your covenant limits, a rate spike can create a real problem, fast.

The goal is not to have zero exposure to rate movements. That is impossible. The goal is to choose your exposure consciously, understand what you are carrying, and manage what you have left.

The real problem: corporate debt visibility gaps

Before any strategy can work, you need one thing: visibility.

Ask yourself honestly:

• Do you have a single, up-to-date view of all your debt across every entity and currency?

• Can you instantly see how much of your portfolio is floating versus fixed?

• Do you know what a 1% rate increase does to your interest expense this year?

• Do you have enough notice before key rate resets or debt maturities to actually do something about them?

If the answer to any of those is "we'd need to pull that together in a spreadsheet," data visibility is the problem that needs solving first.

How a treasury management system turns rate risk into a managed position

A modern treasury management system (TMS) does not make rates go down. But it gives your team the visibility and tools to manage exposure properly, instead of reacting to surprises.

Here is what that looks like in practice:

• One place for everything. All debt, all swaps, all caps and floors, consolidated in a single system with live data. No more piecing together positions from multiple sources.

• Instant scenario modeling. Want to know what happens to your cash flow if rates jump another 150 basis points? Run the model in minutes, not days.

• No more missed dates. Rate resets, maturity deadlines, and refinancing windows are surfaced automatically, before they become urgent.

• Forecasts that reflect reality. When your debt portfolio data feeds directly into your cash forecasting engine, your 13-week and 12-month forecasts actually reflect the rate environment you are living in, not the one you planned for six months ago.

• Hedge management without the manual work. If you are using interest rate swaps to manage exposure, the TMS tracks the full lifecycle, including the documentation and effectiveness testing required for ASC 815 or IFRS 9 compliance. That alone saves treasury and accounting teams significant time every quarter.

Three steps to strengthen your interest rate risk management today

You do not need a full treasury transformation to start managing rate risk better. Start here:

1. Get a consolidated view of your debt. If you cannot see everything in one place today, make that your first priority.

2. Run a rate sensitivity analysis. Model what a +100bps and +200bps scenario does to your interest expense and cash flow. If the numbers are uncomfortable, better to know now.

3. Check your refinancing calendar. Any debt maturing in the next 18 to 24 months needs to be on your radar. Planning ahead gives you options. Waiting until the last minute does not.

The bottom line: build the infrastructure before the next rate shock

Rates have a way of reminding everyone that they matter, usually at the worst possible moment. The treasury teams that are best positioned right now are not the ones who predicted today's environment correctly. They are the ones who built the infrastructure to respond to whatever environment shows up.

Visibility, scenario analysis, and a structured approach to managing your debt portfolio are not luxury items. When rate uncertainty can reset your planning assumptions overnight, they are essential.
