Hong Kong’s interbank offered rate (HIBOR) continues to decline. According to data from the Hong Kong Association of Banks on June 16, the 1-month HIBOR fell to 0.52452%, marking its lowest level since June 2022—a nearly three-year low. This low-interest trend not only eases mortgage repayment pressure but may also trigger structural adjustments in asset allocation.
What is HIBOR?

HIBOR (Hong Kong Interbank Offered Rate) is the benchmark interest rate for interbank lending in Hong Kong. It is determined based on market demand for HKD deposits, and its fluctuations directly reflect changes in liquidity conditions:
When liquidity is tight: HIBOR rises, increasing borrowing costs.
When liquidity is abundant: HIBOR falls, lowering financing barriers.
3 Key Reasons Behind HIBOR’s Decline

Global Risk-Averse Capital Flows Back
Due to political uncertainties, U.S. stock market volatility has intensified, prompting some investors to shift from dollar-denominated assets to Hong Kong markets for risk diversification. This influx of capital has boosted HKD liquidity, putting downward pressure on HIBOR.
IPO Activity Attracts Mainland Capital
Recent rebounds in Hong Kong stocks, coupled with large-scale IPOs, have drawn mainland capital into the market through the "Stock Connect" program. This further increases banking system liquidity, reducing interbank funding pressures and driving HIBOR lower.
HKMA Injects Liquidity
To stabilize the HKD exchange rate, the Hong Kong Monetary Authority (HKMA) has been injecting liquidity into the market since May. The increased short-term supply of funds has pushed interbank rates down.
Market Effects of the Low-Interest Environment

1. Significant Relief for Mortgage Borrowers
For homebuyers and businesses, lower HIBOR means reduced interest expenses. Taking a HK$5 million, 30-year H+1.3% mortgage as an example:
When HIBOR was 4.2%: | The effective rate was 4.8%, but due to a cap rate of 3.5%, monthly payments were ~HK$22,455. |
With HIBOR at 0.53%: | The effective rate drops to 1.83%, slashing monthly payments to HK$18,050. Monthly savings: HK$4,405, accumulating to over HK$100,000 in two years. |
2. Declining Appeal of Fixed Deposits
When bank deposit rates (e.g., 1%) fall below inflation (~2%), real purchasing power erodes over time, pushing conservative investors toward riskier assets like stocks and real estate for wealth preservation.
3. Boosts Consumption & Economic Activity
Consumer side: Low interest rates discourage savings, encouraging spending and investment, thereby stimulating economic activity.
Corporate side: Lower financing costs ease operational burdens, freeing up capital for expansion, R&D, and innovation. Increased consumer spending also enhances corporate profitability and market confidence.
Conclusion
The sustained low HIBOR environment brings positive impacts, including lighter mortgage burdens, stimulated consumption, and increased risk-asset investments. However, investors should remain cautious about future market shifts, as HIBOR trends can be influenced by capital flows and global economic conditions. Flexibility in strategy is key.
