ECB Key Interest Rates: What are they and how do they influence mortgage lending?

What are basic interest rates in 30 seconds?
Basic interest rates are the main instruments used by the European Central Bank (ECB) to control inflation and influence the eurozone economy.

Changes in these rates directly influence Euribor, housing loans, business loans, and savings remuneration.

What are the ECB's key interest rates?
Key interest rates are the official rates set by the ECB for eurozone countries. There are three main rates:

Deposit facility rate;
Main refinancing operations rate;
Loss lending facility rate.

These three rates serve as a benchmark for the financial system and influence the rates charged by banks to households and businesses.

1. Deposit facility rate
What is this?

It is the remuneration that the ECB pays to banks when they deposit money with the Central Bank for very short periods. Since 2024, this has become the main rate used by the ECB to guide the monetary policy of the eurozone.


Why is it important?

This rate directly influences money market rates and has a particularly significant impact on the evolution of Euribor.

When the ECB reduces this rate, banks tend to lend money at lower costs, favoring access to credit and stimulating the economy. Conversely, when you increase it, credit tends to become more expensive, helping to curb inflation.


What is the relationship with mortgage lending?

Euribor reflects market expectations about the evolution of ECB interest rates. Therefore, changes in the deposit rate end up influencing the installments of mortgage contracts with variable rates.

2. Main refinancing operation rate
What is this?

It is the rate that banks pay when they obtain financing from the ECB for a period of one week, upon delivery of guarantees (collateral). These operations provide a significant portion of the liquidity to the European banking system.


Why is it important?

This rate influences the cost of funding for banks. When it rises, banks face higher costs to obtain liquidity and tend to pass this increase on to loans granted to households and businesses. When it falls, credit generally becomes more accessible, encouraging consumption, investment, and economic activity.

Why is this rate less discussed?

Historically, this was considered the ECB's main benchmark rate. However, since the review of the operational framework of monetary policy in 2024, the deposit rate has taken on a central role in guiding monetary policy.

3. Loan-lending facility rate
What is this?

It is the rate applied to very short-term loans granted by the ECB to banks when they need immediate liquidity.

Why is it important?

This rate acts as an upper limit for money market rates. Since banks can turn to the ECB for urgent funding, they are unlikely to accept paying significantly higher rates than those offered by this facility.

For this reason, this rate is often described as the "ceiling" of the ECB's interest rate corridor.

How do policy rates influence the economy?

ECB decisions have effects that go far beyond the banking sector.

When rates rise:
Credit becomes more expensive;
Loan repayments tend to increase;
Consumption and investment slow down;
Demand decreases;
Inflation tends to slow down.


When rates fall:
Credit becomes more accessible;
Households have greater financial capacity;
Business investment increases;
Economic activity is stimulated;
Inflation may gain momentum.

Frequently asked questions about key interest rates
Why does the ECB change interest rates?

The main objective is to maintain price stability. When inflation is very high, the ECB tends to raise rates. When the economy weakens or inflation is under control, you can choose to lower interest rates to stimulate economic activity.


What happens when the ECB raises interest rates?

Money becomes more expensive for banks, so credit becomes more expensive, loan repayments tend to increase, and consumption slows down. The goal is to reduce pressure on prices and control inflation.


What happens when the ECB lowers interest rates?

Loans tend to become more accessible, investment increases, and the economy gains momentum.


Why does Euribor react to ECB decisions?

Because Euribor reflects market expectations about the future evolution of interest rates in the eurozone.


Which of the ECB's rates has the most impact on Euribor?

Currently, the deposit facility rate is considered the main reference for the ECB's monetary policy and the one that most influences the
Evolution of money market rates, including Euribor.


When the ECB changes interest rates, does the mortgage payment change immediately?

Not necessarily. The payment is only revised on the date stipulated in the loan agreement, usually three, six, or twelve months later, depending on the Euribor review period.


How often does the ECB change interest rates?

The ECB Governing Council meets regularly to assess the economic situation and may maintain, raise, or lower policy rates whenever it deems necessary to meet the objective of price stability.


Why should homeowners follow ECB decisions?

For those with variable-rate mortgages, ECB decisions are a key indicator of future benefit trends. Following ECB decisions allows for anticipating trends, evaluating loan renegotiation opportunities, and making more informed financial decisions.
