Applying for a home loan in Singapore is a long-term financial commitment. Naturally, you’d want to ensure you not only start with a low interest rate, but you also want the reassurance that your interest rate won’t increase dramatically overnight.

In trying to find a home loan package that fit this criteria, banks began to offer what is known as a fixed deposit linked rate.

What is a fixed deposit linked rate?

A fixed deposit linked rate is a home loan package offered by a bank, where the home loan interest rates are pegged to the bank’s fixed deposit interest rate.

For example, you may see a home loan package that looks like this:

The first half (in the above example, “DBS FHR6”) refers to the banks’ fixed deposit interest rate. What is FHR6 now? It’s 0.75 per cent (as of June 8, 2022), the interest rate for an six-month fixed deposit with DBS. This part of the home loan interest rate may change over the loan tenure, but only if the bank also changes the interest rate for this particular fixed deposit.

The second half (in this case, 1.30 per cent) is called the spread. This represents the bank’s profits, and unlike the first half of the mortgage rate, this amount will not change during your loan tenure.

Are fixed deposit linked rates a low risk option?

Yes, but up to a point. Technically, the bank should not change their fixed deposit interest rates on a whim. Since interest paid on fixed deposit accounts represent a cost to the bank, it will cause the bank to think twice before raising the interest rate.

Compare this to a board rate - there is nothing stopping the bank from raising board rates, since there is no transparency unlike fixed deposit linked rates.

So if fixed deposit interest rates don’t go up, then your home loan interest rate will also not go anywhere. However, back in 2020, we learnt that banks are more than happy to be “generous” at your expense.

Am I safe with a fixed deposit linked rate?

Remember how the Police warn you “low crime doesn’t mean no crime”? In the same way, you can’t assume that “low risk means no risk”.

Because these home loan packages are based on the bank’s own fixed deposit interest rates, banks can change these interest rates at any time - no need to ask for your permission. Let's look at a cousin of FHR6, known as FHR8.

When FHR8 was introduced in 2018, it was 0.20 per cent. Just two years later, it reached a high of 0.95 per cent. Fortunately on May 4, 2020, FHR8 dropped for the first time to 0.60 per cent.

However, on June 8, 2022, FHR8 rose to 0.85 per cent due to rising interest rates.

Another thing to look out for is the reference fixed deposit rate. Over time, with different customers, banks can also change the fixed deposit interest rate their mortgage loans are pegged to. Here’s an example of what I mean:

This allows the bank to adjust their rates on a more granular level, which means you can never truly anticipate how much of a jump your package may experience when interest rates rise.

But don’t worry, whatever fixed deposit linked rate you were on will still remain. You won’t ever jump from an FHR6 home loan package to an FHR24 home loan package.

Here's what DBS fixed deposit rates linked to home loans look like on June 8, 2022:

But despite all that, fixed deposit linked rates should be relatively safe... right?

Fixed deposit linked rates can be ideal in a rising interest rate environment. When interest rates rose in 2019, there was a corresponding increase in fixed deposit rates. However, when compared to the rest of the market, banks were still offering relatively low fixed deposit linked home loan packages.

Fast forward to 2020 and a free falling interest rate environment, and yet fixed deposit rates that are linked to home loan packages are not falling accordingly. And over the past five years, many banks have introduced then withdrawn fixed deposit linked rates, rather than opt to reduce fixed deposit rates.

Therefore, those taking fixed deposit linked rates should go in with their eyes wide open.

In a rising interest rate environment, fixed deposit linked rates rise as well, but not as quickly. It will therefore still be less volatile than a SORA rate or even a board rate. However, when interest rates fall, fixed deposit linked rates, like fixed rate home loans, will leave you at a disadvantage.

Here are three things to look out for when choosing a fixed deposit linked rate:

1. Lock-in period

If there's one thing we learnt from 2019, it's not to rest on our laurels when fixed deposit linked rates are relatively low. Once the interest rates started to rise (and interest rates are cyclical, so it will happen again confirm plus chop), you'll want to be able to refinance as soon as possible to a better home loan package.

Therefore, choose a fixed deposit linked home loan package that has a short lock-in period, if possible. If you meet certain requirements, you may even find one that has no lock-in period at all!

2. Fixed deposit period

Not all fixed deposit interest rates are made the same. Naturally, the longer the fixed deposit period, the higher the interest rate - but more importantly, ask yourself if such a fixed deposit period is popular in the first place!

Remember, the fixed deposit interest rate represents a cost to the bank, so they shouldn’t increase it unnecessarily because it means they’ll pay their customers more interest. But if it’s an unpopular fixed deposit period, such as 36 months, then the bank may earn more from you than they lose by increasing the interest rate!

3. Is it a local bank or a foreign bank?

When it comes to fixed deposits, the general wisdom is that local banks have significantly more deposits than foreign banks. This also means they have more to lose if they increase their interest rates.

Foreign banks, on the other hand, don’t have as much in fixed deposits, so they may be more willing to increase interest rates to attract more customers! But this also means that if you take up a fixed deposit linked home loan with a foreign bank, you might find yourself paying more interest over time.
