What decision this helps you make: What share of your obligations should be fixed, with which instrument, for how long, and what the hedge costs you if the business changes before the loan matures.

What this topic is

Interest-rate risk management is the practice of measuring how fast your obligations reprice against how fast your income does, then deliberately closing part of that gap. It has two lenses: the earnings lens (what a rate move does to next year's cash) and the value lens (what it does to the worth of anything with a fixed rate attached). And it has a set of instruments that convert an unknown rate into a known one.

Why it matters

Rate moves do not arrive as a bill. They arrive as a reset notice, a covenant calculation that no longer clears, and a refinancing quote that reprices the whole business at once. A company that has built the repricing schedule knows its exposure in dollars per point and can act months early; a company that has not finds out on a reset date, with no time and no leverage.

Who should learn it

Owners and finance leads carrying floating-rate debt, facing a refinancing inside three years, or holding long-lived fixed-rate assets funded with short-term money.

What you will understand

  • Build a repricing gap schedule and convert it into dollars per 100 basis points
  • Translate a rate shock into covenant headroom, not just interest expense
  • Choose between a swap, a cap, a collar, and simply fixing the loan
  • See the traps: index mismatch, tenor mismatch, and the swap break cost
  • Set a fixed-floating policy that is a policy rather than a forecast

Prerequisites

Common misconception

"We fixed the rate, so the interest-rate risk is gone." Fixing converts one risk into another. A fixed loan removes cash-flow risk and adds value risk: the obligation now has a market value that moves against you when rates fall, which shows up as a prepayment penalty or a swap break cost the moment you want to sell the business, refinance, or pay early. A 100% fixed balance sheet with a three-year horizon and a ten-year hedge is not conservative. It is a different bet.
