Major banks are predicting further interest rate hikes in 2026, prompting mortgage-holders to consider locking in their rates. Experts warn that while fixing the rate may protect against future hikes, it may also lock borrowers out of potential rate cuts. Borrowers with tight budgets are advised to review their options and consider fixing their rates, but to do so thoughtfully and after assessing their individual financial conditions. It's also recommended to shop around for competitive rates and to ignore media headlines and focus on what can be controlled.
