NAB has announced increases to its fixed home loan interest rates across all terms — from 1 to 5 years — effective Friday 27 March 2026.
The changes apply to NAB Tailored Home Loans, including NAB Choice Package, Private Package, Portfolio Facility, SMSF, and Overseas Borrower products.
What’s Changed?
Fixed rates have increased across the board, with rises of up to 0.35% p.a. depending on the loan term, LVR tier, and repayment type.
Here’s a snapshot of the key changes for Principal & Interest borrowers (LVR ≤ 60%):
| Fixed Term | Old Rate (p.a.) | Change | New Rate (p.a.) |
|---|---|---|---|
| 1 Year | 5.74% | +0.35% | 6.09% |
| 2 Years | 5.79% | +0.35% | 6.14% |
| 3 Years | 5.94% | +0.35% | 6.29% |
| 4 Years | 6.04% | +0.15% | 6.19% |
| 5 Years | 5.98% | +0.15% | 6.13% |
Interest Only products have also increased by similar margins across all LVR tiers.
Who’s Affected?
- New applicants: Anyone drawing down a fixed rate loan on or after 27 March 2026 will receive the new higher rates — even if the application was submitted before this date.
- Existing customers switching or re-fixing: If you submit a Request to Change form on or after 27 March, the new rates apply.
- Current fixed rate customers: Your existing fixed rate is not affected — the changes only apply when your current term expires and you choose to re-fix.
What About Rate Lock?
If you’re in the process of buying a property and haven’t settled yet, Rate Lock could protect you from further increases. Without it, you’ll receive whatever the fixed rate is on the day of drawdown.
This is especially important in the current environment where fixed rates can move at any time without notice.
What Should You Do?
If you’re considering fixing your rate — or your current fixed term is about to expire — now is the time to act. Here’s what we recommend:
- Review your current loan: Check when your fixed term expires and what rate you’ll roll onto.
- Compare your options: Fixed vs variable, and across multiple lenders — NAB isn’t the only game in town.
- Talk to a broker: We can help you navigate the best strategy based on your financial goals and borrowing capacity.
The Bigger Picture
NAB’s move signals that the big banks expect wholesale funding costs to remain elevated. While the RBA has started cutting the cash rate, fixed rates are driven by swap rates — and those are influenced by bond markets and global conditions, not just the cash rate.
This is a reminder that fixed rates don’t always follow variable rates down. If you’ve been waiting for fixed rates to drop, this increase may prompt a rethink.
