If you want to save every penny on your mortgage, you must closely follow the trends in Hong Kong HIBOR rates. The latest data for May 2025 shows that the one-month HIBOR has dropped to 0.96%, with the actual HIBOR-based mortgage (H-plan) interest rate at just 2.26%, far below the capped rate of 3.5%. Most Hong Kong banks currently offer H-plans that are more cost-effective than Prime-based mortgages (P-plans), and choosing an H-plan can directly reduce your interest burden. By comparing different banks’ H-plan offers and making good use of cash rebate incentives, you can further lower your mortgage costs.

Key Points

• HIBOR mortgage rates fluctuate with the market; when rates fall, your mortgage interest decreases, helping you save on repayment pressure.
• Different banks’ HIBOR mortgage plans vary in interest rates and cash rebates; you should compare rates, capped rates, and rebates to find the most suitable plan.
• Regularly monitor Hong Kong HIBOR rate trends and consider refinancing when rates drop to further reduce mortgage costs.
• Make good use of cash rebates offered by banks and plan their usage wisely to alleviate initial mortgage pressure and increase financial flexibility.
• Choosing between an HIBOR mortgage or a P-plan should be based on your personal risk tolerance and repayment needs, flexibly adjusting your mortgage strategy for the best cost-saving outcome.

What is a HIBOR Mortgage?

How It Works

If you want to understand what a HIBOR mortgage (H-plan) is, it’s quite simple. An H-plan is based on the Hong Kong Interbank Offered Rate (HIBOR), with the bank adding a fixed percentage on top, typically using the one-month HIBOR. This rate fluctuates with the market, and each time your mortgage is renewed, the bank recalculates your mortgage interest based on the latest Hong Kong HIBOR rate. An H-plan is a floating-rate mortgage, so when market rates fall, your mortgage interest also decreases.

Tip: H-plans come with an annual interest rate cap (capped rate), so even if market rates surge, you won’t pay above this cap.

Interest Rate Calculation

When you apply for an H-plan, the bank calculates the actual interest rate using “HIBOR + fixed spread.” For example, in 2023, the one-month HIBOR was around 0.44%, and banks typically add 1.5%, resulting in an actual rate of about 1.94%. In 2025, the capped rate for H-plans is approximately 3.5%. If Hong Kong HIBOR rates continue to fall, the interest you actually pay will be below the capped rate. Banks adjust your mortgage rate monthly or quarterly based on the latest HIBOR, allowing you to benefit from market rate reductions.

H-Plan vs. P-Plan

You might wonder, what’s the difference between an H-plan and a P-plan? A P-plan (Prime-based mortgage) is based on the bank’s prime rate, which is usually more stable but has a higher baseline, typically 2.5% or more. An H-plan, on the other hand, fluctuates with Hong Kong HIBOR rates, and when market rates fall, H-plans are generally more cost-effective than P-plans.

• H-plan: Floating rate, heavily influenced by market conditions, with a capped rate for protection.
• P-plan: More stable rate, but higher baseline, less responsive to market changes.

Whether you choose an H-plan or a P-plan should depend on your risk tolerance and judgment of market trends.

Recent Changes

If you’ve been following Hong Kong HIBOR rates, you’ll notice significant fluctuations in recent years. In 2023, the one-month HIBOR once rose to 4.5%, significantly increasing mortgage interest costs. However, starting in the second half of 2024, Hong Kong HIBOR rates noticeably declined. By May 2025, the one-month HIBOR has fallen to between 0.58% and 0.62%. This change has reduced the actual H-plan interest rate to below 2.87%. When you make mortgage payments, your monthly interest expenses are significantly lower, greatly reducing repayment pressure.

2025 Forecast

According to Morgan Stanley’s latest report, experts predict that Hong Kong HIBOR rates will continue to decline in 2025. The report indicates that the one-month HIBOR will drop from 4.5% in the first half of 2024 to 2.75%. This forecast reflects the possibility of the U.S. Federal Reserve cutting rates, driving Hong Kong HIBOR rates downward. If you choose an H-plan, your actual mortgage rate could fall to 3.25%. This trend helps you reduce your mortgage burden, especially for those applying for new mortgages or considering refinancing.

Impact on Mortgages

When Hong Kong HIBOR rates fall below 1%, the interest portion of your monthly mortgage payments decreases significantly. You can pay off the principal faster, and overall interest expenses are reduced. If you choose an H-plan, the current rate is well below the capped rate, making mortgage costs significantly lower. However, if Hong Kong HIBOR rates remain high for an extended period in the future, a P-plan (Prime-based mortgage) may be more stable and suitable for those seeking consistent repayments. You should flexibly choose the most suitable mortgage plan based on your financial situation and market trends.

Tip: You can regularly monitor Hong Kong HIBOR rate trends and consider refinancing when rates drop to save even more money.

You can choose the most suitable bank based on factors like interest rates, cash rebates, and lock-in periods.

HSBC

As a market leader, HSBC’s HIBOR mortgage plan has always caught your attention. In 2025, HSBC offers an “H+1.3%” rate structure with a capped rate of 3.5%. When you apply, the bank calculates the actual interest rate based on the HIBOR published by the Hong Kong Association of Banks. HSBC offers a cash rebate of up to 1.2% of the loan amount, with a typical lock-in period of 2 years. HSBC uses its proprietary HIBOR as the calculation basis, closely aligned with market HIBOR trends.

Bank of China (Hong Kong)

Bank of China (Hong Kong)’s HIBOR mortgage plan is also highly competitive. If you choose BOC, you’ll see an “H+1.4%” rate with a capped rate of 3.4%, slightly lower than HSBC.

Tip: When choosing an HIBOR mortgage, pay attention to whether the bank has recently lowered its capped rate.

Money-Saving Tips for Mortgages

Selection Tips

If you want to save money on your mortgage, you need to know how to choose the right mortgage plan. You can make your choice based on your financial situation and market trends. If you prioritize low interest rates and are willing to tolerate rate fluctuations, an H-plan (HIBOR mortgage) is more suitable for you. When Hong Kong HIBOR rates fall, your mortgage interest decreases, reducing overall repayment pressure. If you prefer stable payments and want to avoid market fluctuations, a P-plan (Prime-based mortgage) is more suitable. You should first calculate your monthly payments, assess whether you can handle the risk of rising rates, and then make your decision.

Tip: You can use online mortgage calculators to simulate monthly payments under different interest rates, helping you make informed decisions.

Leveraging Cash Rebates

When you apply for a mortgage, banks typically offer cash rebates or other incentives. You can make good use of these rebates to alleviate initial mortgage pressure. For example, some Hong Kong banks offer cash rebates of 1% to 1.2% of the loan amount. You can use this rebate to cover legal fees, renovation costs, or as an emergency reserve. You can also compare the rebate amounts and conditions across banks to choose the most advantageous plan.

• You should note that rebate amounts are tied to the lock-in period. If you repay early or refinance within the lock-in period, the bank may reclaim part of the rebate.
• You can inquire about banks’ latest promotions and choose products with higher rebates to further reduce mortgage costs.

Note: After receiving a cash rebate, plan its usage carefully to avoid overspending.

Refinancing Timing

If you want to save more money, consider refinancing at the right time. When Hong Kong HIBOR rates fall and the market offers lower rates or higher rebates, you can consider refinancing to another bank. When refinancing, you should confirm whether the lock-in period has ended, as you may otherwise need to pay penalties or return part of the rebate. You can compare different banks’ mortgage rates, capped rates, and rebates to choose the most suitable new plan.

• You should regularly monitor market information, especially U.S. Federal Reserve rate cut announcements, as these directly impact Hong Kong HIBOR rates.
• You can consult professional mortgage advisors to understand the refinancing process and key considerations to ensure a smooth transition.

Tip: After refinancing, review your financial situation to ensure the new plan genuinely helps you save money.

If you want to maximize savings on your mortgage in 2025, you can choose an HIBOR mortgage and stay updated on the latest rates and cash rebates from major Hong Kong banks.

• You should choose the most suitable plan based on your financial situation.
• You should regularly monitor market trends and refinance flexibly when rates drop.

Reminder: Mortgage interest is calculated in U.S. dollars (USD), so refer to the exchange rate on the day to ensure the plan meets your needs.
