Mechanism
How does a SWAP Mortgage work?

With a SWAP mortgage, two separate transactions are concluded: a SARON mortgage with a variable interest rate based on the —and an interest rate swap, in which the variable rate is exchanged for a fixed rate—with a term that can be customized.

The effect is symmetrical: When interest rates rise, Mortgage costs increase, but at the same time, a profit is generated on the swap. When interest rates fall, Mortgage rates decrease, while the swap incurs a loss.

Comparison
of SWAP and fixed-rate mortgages

Similar at first glance—but fundamentally different in practice:

Fixed-rate mortgage

The fixed-rate mortgage stands out for its simple structure, fixed interest rate, and high transparency. While flexibility is limited, the risk is low.

SWAP Mortgage

The SWAP mortgage has a complex structure and an indirectly fixed interest rate, which limits transparency. Its flexibility depends directly on the swap agreement and is therefore limited. In addition, the use of derivatives entails an increased risk.

Conclusion: The SWAP mortgage is a technically more complex alternative to a fixed-rate mortgage. It is not a practical option for private homeowners.

SWAP mortgages are complex, and the risks are difficult to assess. They are completely unsuitable for homeowners. A better option is a sound strategy using fixed-rate or Saron mortgages.

FAQ

Frequently Asked Questions
Answers about SWAP mortgages

No. A fixed-rate mortgage is a simple product with a fixed interest rate. A swap mortgage achieves a similar effect but is based on a more complex structure that involves additional risks.

The most significant risks include the high level of complexity, counterparty risk with respect to the bank as the swap partner, and potential costs associated with early exit.

An interest rate swap is a financial instrument in which variable interest rates are exchanged for fixed interest rates. It is used to hedge against interest rate risk.

Because they are complex, involve additional risks, and do not offer a clear advantage over simpler Mortgage loan models.

Risk
Understanding the Key Risks of SWAP Mortgages

A key point: The interest rate swap has its own market value. This means that an early exit can result in a significant gain or loss—and that, in addition to interest rate risks, there are also default risks, known as counterparty risks.

Unlike with traditional mortgages, credit risks and counterparty risks must also be taken into account in pricing and risk assessment.

Conclusion
Our assessment of the SWAP Mortgage

For most customers, the SWAP mortgage is considered too complex and not transparent enough, with no clear cost advantage apparent. In many cases, a well-negotiated Fixed-rate mortgage or a SARON mortgage is the better and simpler solution.
