What it means
When you take out a floating-rate loan, the lender needs a reference point for what the base cost of money is today. EURIBOR is that reference for euro lending.
The loan agreement normally says something like "three-month EURIBOR plus 2%", and the rate is reset at regular intervals as the benchmark changes. The rate is administered by a European body that collects data from a panel of banks and calculates the benchmark using a defined method.
After scandals involving other benchmarks, the process was tightened so that rates rely more heavily on actual transactions where possible and on clear, auditable rules for the rest. Companies should still read the loan documents to see what happens if a benchmark is changed or stops being published.
For a finance manager, the main point is cash-flow risk. If EURIBOR rises, the interest cost on a floating loan rises with it, and budgets can be blown.
Many firms use interest rate swaps (contracts that exchange a floating rate for a fixed one) or caps to limit this exposure. The tenor, or length of the period, matters.
A three-month rate is reset four times a year, while a six-month rate is reset twice. Interest is usually calculated using the actual number of days in the period divided by 360, which is a market convention.
EURIBOR can move below zero, and in past years it did so for an extended period. Loan contracts therefore specify whether the benchmark can be negative or whether a floor of zero applies.
This detail may seem small but it can change the interest bill materially. EURIBOR is often confused with LIBOR, a similar benchmark formerly used for several currencies, including a euro version called EuroLIBOR.
They are separate rates produced by different processes. If you have an old contract that refers to a discontinued benchmark, check which replacement rate applies.
In practice
Real-world examples.
Example
A German manufacturer borrows to build a new warehouse on a floating-rate loan linked to 3-month EURIBOR. The treasurer builds a forecast that shows interest costs under three different benchmark levels so that the board can see the risk.
Example
A property investor in Spain has a mortgage priced at 12-month EURIBOR plus 1%. When the benchmark rises, the monthly payment increases at the next annual reset, so she sets aside extra cash in advance.
Example
A Dutch software company agrees a swap with its bank to pay a fixed rate in exchange for receiving 3-month EURIBOR. The swap offsets the floating payments on its credit line, which gives the finance team a predictable interest cost.
Formula
Calculation
Interest for the period = loan amount x (EURIBOR + margin) x days in period / 360
Worked example: a company borrows 1,000,000 euros on a floating-rate loan priced at 3-month EURIBOR plus 1.50%. Assume that 3-month EURIBOR is set at 2.00% for the period, and the period is 90 days.
Step 1: All-in annual rate = 2.00% + 1.50% = 3.50%.
Step 2: Interest = 1,000,000 x 3.50% x 90 / 360.
Step 3: 1,000,000 x 0.035 = 35,000 for a full year, and 35,000 x 0.25 = 8,750 euros for the 90 days.
If EURIBOR rose to 3.00% at the next reset, the rate would be 4.50% and the quarterly interest would be 11,250 euros, an extra 2,500 euros for the period.Case study
Seen in the real world.
Marlow Logistics is a fictional delivery group with a 10 million euro credit facility priced at 3-month EURIBOR plus 2%. For several years the benchmark was low, and the company did not pay much attention to interest costs.
When EURIBOR climbed steadily over a single year, the finance director saw her quarterly interest bill nearly double. The budget had assumed a flat benchmark, so profit forecasts had to be revised in a hurry.
In this illustrative story, Marlow responded by fixing the rate on 60% of the facility using an interest rate swap and by adding benchmark sensitivity to every forecast. The company still carries some floating-rate risk, but the board now understands how much and why.
Watch out
Common mistakes.
- Assuming EURIBOR is a rate set by one central authority, when it is a benchmark calculated from submissions and data from a panel of banks.
- Forgetting to add the lender's margin, which means the true rate you pay is higher than the quoted benchmark.
- Ignoring what the contract says about negative rates, floors and replacement benchmarks.
Questions
People also ask.
Is EURIBOR the same as the European Central Bank's policy rate?
No. The central bank's rates influence EURIBOR, but EURIBOR is a separate market benchmark for bank-to-bank borrowing.
How often does the rate on my loan change?
It depends on the tenor in your agreement, for example every three months for a 3-month EURIBOR loan.
How can a company protect itself from rising EURIBOR?
It can use an interest rate swap, a cap, or a fixed-rate loan, each of which has its own cost and trade-offs.
