Why Your Home Loan Instalment Dropped? And Why You Might Still Be Overpaying (Singapore 2026)

If your home loan instalment recently dropped, it might feel like good news.

Lower monthly payments usually mean you’re saving money… right?

Not always.

In many cases, a lower instalment simply means your loan has transitioned from a fixed rate to a floating rate and you could still be paying more than necessary.

Here’s what’s really happening and what you should do next.

Why Did Your Home Loan Instalment Drop?

For most homeowners in Singapore, this happens after the lock-in period ends.

During the first 2–3 years, your loan is usually on a fixed rate.
After that, it automatically switches to a floating rate, typically pegged to SORA (Singapore Overnight Rate Average).

If SORA is lower than your previous fixed rate, your instalment will decrease.

What Happens After Your Lock-In Period Ends

Once your fixed package expires, your loan typically converts to:

SORA + bank spread

For example:

• 3M SORA: 1.08%
• Bank spread: +0.80%
• Total rate: 1.88%

This is where most homeowners stop paying attention and where overpaying begins.

The Part Most People Miss: The Bank Spread

While SORA is the benchmark rate, the bank spread is what you’re actually locked into.

Older loan packages often come with higher spreads (e.g. +0.70% to +1.00%), while newer packages may offer lower spreads (e.g. +0.25% to +0.40%).

So even if your instalment dropped, you could still be:

• Paying a higher spread than current market rates
• Missing out on better refinancing options
• Overpaying every month without realising it

Lower Instalment ≠ Best Rate

This is the key mistake.

Many homeowners assume:

“My instalment went down, so my loan is good.”

But in reality:

• Your rate is just lower than before
• Not necessarily the best available today

There’s a big difference.

The Risk of Staying on a Floating Rate

Floating rates like SORA are not fixed.

If interest rates rise again:

• Your instalment will increase
• Your total interest paid over time will go up

Waiting until rates rise is usually too late.

By then, you’ve already paid more than necessary.

When Do Most People Review Their Loan?

Most homeowners only take action when:

• Their instalment increases significantly
• Interest rates are all over the news

But by that point, they’ve already overpaid for months (or even years).

What Should You Do Now?

If your instalment recently dropped, don’t assume everything is optimised.

Instead, ask:

• What is my current rate (SORA + spread)?
• How does it compare to today’s market rates?
• Am I still on a competitive package?

Even if you’re not overpaying right now, reviewing your loan can help you:

• Lock in a better rate
• Reduce future risk
• Optimise your mortgage strategy

Should You Refinance or Reprice?

Depending on your situation, you may consider:

Repricing (same bank):

• Faster process
• Lower admin cost
• Limited to your current bank’s options

Refinancing (switch banks):

• Access to better rates across multiple banks
• Potential legal subsidies
• More flexibility

The right choice depends on your current package and financial goals.
