Introduction
The US Federal Reserve’s 25-basis-point rate increase on 17 September 2026 was quickly reflected in Hong Kong, with the HKMA raising its Base Rate to 4.25%. Although Hong Kong banks have so far held their prime rates, borrowing costs have already risen significantly from the lows of 2025. A further US rate rise could increase pressure on Hong Kong banks to follow.
The timing is difficult. Hong Kong’s commercial property market remains under pressure, while some residential mortgages are in negative equity. At the same time, much of the market remains exposed to floating rates: 61% of new mortgages approved in July 2026 were HIBOR-linked.
For borrowers and lenders, the practical question is therefore straightforward: what happens to existing financing arrangements if rates rise further or property values fall?
Why this matters
Higher rates affect more than interest payments. For property-backed lending, three risks can arise together:
- Interest cover: higher borrowing costs can cause borrowers to breach financial covenants even where rental income remains stable.
- Loan-to-value: falling property valuations can push an otherwise performing loan above its permitted LTV ratio.
- Cross-default: a breach of one facility may trigger defaults elsewhere in the borrower’s financing structure.
Take a landlord with a 60% LTV covenant and a 1.5x interest-cover requirement. A decline in the value of its properties could push LTV above the agreed limit. If rates rise at the same time, interest cover may also fail. The borrower could then face default interest, restrictions on cash and, ultimately, enforcement.
Lenders face risks too. A mortgagee selling secured property must take reasonable care to obtain its true market value, following the long-established principle in Tse Kwong Lam v Wong Chit Sen. Selling into a weak market therefore needs careful handling.
The better approach for both sides is to address problems before a technical breach becomes a default.
What borrowers should do
- Stress-test the numbers
Model the effect of HIBOR rising by another 1–2% and property values falling by 10–15%. Identify which financial covenant is likely to come under pressure first and when it will next be tested. - Speak to lenders early
If a breach looks possible, seek a waiver or covenant adjustment before it occurs. Negotiating with headroom is generally preferable to negotiating after a default, when cross-default provisions may already have been triggered. - Review interest-rate protection
Consider whether unhedged floating-rate exposure should be capped or swapped, and check how existing hedging arrangements interact with the facility and security documents. - Check compliance reporting
Compliance certificates should accurately reflect the borrower’s position. Directors should be particularly careful about certifying compliance where a breach is known or expected.
What lenders should do
- Update valuations
Review assets already on watch lists and identify loans where a relatively modest fall in value could cause an LTV breach. - Check security
Confirm that mortgages, charges, insurance, rental assignments and other security remain properly documented and registered, particularly where finance documents have been amended. - Prepare for enforcement
Even where enforcement is not immediately contemplated, lenders should understand their options, including receivership and sale, and ensure that any sale process can withstand scrutiny over the price obtained. - Document any waiver carefully
A waiver should preserve the lender’s rights and deal expressly with outstanding defaults, revised financial covenants, hedging arrangements and existing security.
Legal and regulatory points
Facility agreements should be reviewed carefully, particularly provisions dealing with LTV and interest cover, valuations, cure rights, default interest and material adverse change.
Security also needs checking. Land charges must be properly registered, while charges created by Hong Kong companies are subject to registration requirements under the Companies Ordinance. Care is also needed when amending facilities so that existing security is not inadvertently prejudiced.
For lenders, the key issue is not simply whether enforcement rights exist, but how and when they are exercised. In a difficult property market, valuation evidence, the sale process and the decision-making trail become increasingly important.
Outlook
Hong Kong interest rates will continue to be heavily influenced by US monetary policy, although local prime rates and HIBOR will not necessarily move in lockstep with the HKMA Base Rate.
For borrowers, the priority should be identifying covenant problems while there is still time to address them. For lenders, it should be understanding which loans are vulnerable and ensuring that security, valuations and enforcement options are in order.
The real lesson from September’s rate move is not to predict the next interest-rate decision. It is to make sure the financing documents and the underlying business can withstand it.
