Overview
– The Hong Kong Interbank Offered Rate (HIBOR) is the benchmark interest rate quoted in Hong Kong dollars that banks charge one another for unsecured wholesale loans in the Hong Kong interbank market.
– HIBOR is published daily (around 11:00 a.m. Hong Kong time) for multiple tenors (overnight, one week, one month, three months, six months, one year, etc.) and is widely used as a reference rate for loans, mortgages, floating-rate notes, swaps and other financial products denominated in HKD.

How HIBOR is determined
– A panel of contributing banks (historically 20 banks designated by the Hong Kong Association of Banks) submits the rates at which they believe they can borrow unsecured funds in the Hong Kong interbank market.
– The calculation typically discards the three highest and three lowest submitted rates, then averages the remaining quotes to produce the published HIBOR for each tenor.
– The published HIBOR series is therefore a contributed, survey-based benchmark (as opposed to strictly transaction-based benchmarks that rely only on actual executed trades).
Primary uses of HIBOR
– Floating-rate lending and deposits: many bank loans and mortgages in Hong Kong use HIBOR plus a spread.
– Floating-rate notes (FRNs): coupon resets tied to a specified HIBOR tenor plus a spread.
– Derivatives and hedges: interest rate swaps, cross-currency swaps and FX trades frequently reference HIBOR for HKD legs.
– Pricing and valuation: bonds, structured products and corporate debt denominated in HKD commonly use HIBOR as the discount or reference rate.
Illustrative example
– A one‑year FRN paying “one‑year HIBOR + 35 basis points” will have its coupon reset each year to the prevailing one‑year HIBOR plus 0.35%. If one‑year HIBOR is 4.00% on reset date, coupon = 4.00% + 0.35% = 4.35% for the next year.
Criticism and vulnerabilities
– Submission-based nature: because HIBOR relies on banks’ contributed quotes rather than exclusively on actual trade data, it can be exposed to inaccuracy or manipulation if contributors misstate their borrowing costs.
– Liquidity and volatility: in stressed market conditions (for example, during crises) interbank liquidity can dry up and the submitted quotes mayTitle: What Is the Hong Kong Interbank Offered Rate (HIBOR)? — Explanation, Issues, and Practical Steps
Overview
– HIBOR (Hong Kong Interbank Offered Rate) is the benchmark interest rate quoted in Hong Kong dollars that banks charge one another for unsecured short-term wholesale loans in the Hong Kong interbank market.
– It is published daily for multiple tenors (overnight, 1-week, 1-month, 3-month, 6-month, 1-year, etc.) and is widely used as a reference for mortgages, loans, floating‑rate notes, swaps and other HKD-denominated financial products.
– Sources: Investopedia; Hong Kong Monetary Authority (HKMA).
How HIBOR is calculated
– A panel of contributing banks (historically 20 banks determined by the Hong Kong Association of Banks) submits the rates at which they would lend/borrow in the interbank market for each tenor.
– For each tenor the highest three and lowest three submissions are discarded; the arithmetic mean of the remaining 14 contributions is published as HIBOR for that tenor (published around 11:00 a.m. Hong Kong time).
– Because it is largely based on contributed quotes rather than only executed transactions, HIBOR is classified as a submission-based benchmark.
Common uses
– Floating-rate loans and mortgages: many HKD loan products reset to HIBOR + spread.
– Floating-rate notes (FRNs): coupon payments tied to a specified HIBOR tenor plus a margin.
– Interest rate and cross-currency derivatives: swaps and hedges referencing HKD funding costs commonly use HIBOR.
– Pricing/valuation: corporate and government securities in HKD often use HIBOR curves for discounting or valuation.
Example (simple)
– A one-year FRN paying “1-year HIBOR + 35 basis points”: if 1‑year HIBOR is 4.00% at reset, coupon = 4.00% + 0.35% = 4.35% for the coming year.
Criticisms and controversies
– Manipulation risk: like other submission-based rates (e.g., LIBOR historically), HIBOR can be vulnerable to inaccurate submissions if contributors have incentives to misstate their perceived borrowing costs. Hong Kong investigated possible manipulation in 2013; the fixing mechanism was reviewed but the episode highlighted risks.
– Market liquidity and volatility: in stressed conditions, the interbank market can become illiquid, making submitted quotes less reliable as reflections of actual funding costs.
– Global reform context: following the LIBOR scandals and global benchmark reform, there has been a push toward transaction‑based overnight risk‑free rates (RFRs) such as SONIA (UK), SOFR (US) and HONIA (Hong Kong). The HKMA has encouraged adoption of HONIA as an alternative HKD benchmark.
Transition to HONIA and benchmark reform
– HONIA (Hong Kong Overnight Index Average) is the unsecured overnight rate for HKD based more on actual transactions and has been promoted by the HKMA as the HKD risk-free reference rate.
– Market participants have been encouraged to develop HONIA‑linked products and to include robust fallback provisions in contracts that currently reference HIBOR.
– The broad global trend is to move from term, submission-based benchmarks toward overnight, transaction-based RFRs and to provide clear fallbacks and spread-adjustment methodologies where needed.
Practical steps — what different stakeholders should do
For borrowers (individuals and corporates)
1. Review contract reference rates and fallback language: check loan/mortgage/derivative agreements for explicit fallback provisions if HIBOR becomes unavailable or is replaced.
2. Consider interest-rate strategy: evaluate whether to keep a HIBOR-linked floating rate, switch to a fixed rate, or use HONIA-linked alternatives where available.
3. Use hedges and risk tools: consider interest-rate swaps, caps or collars to limit exposure to rising HIBOR; ensure counterparty and instrument reference rates match your intent.
4. Negotiate spreads: if switching to a new benchmark (e.g., HONIA), verify any spread adjustments and how they are calculated.
For lenders and banks
1. Strengthen governance and submission controls: tighten policies, audit trails and oversight for rate submissions to benchmark administrators.
2. Enhance product documentation: ensure loan, deposit and derivative documentation includes robust fallback language referencing recognized RFRs and spread adjustment methodologies.
3. Develop market-making and hedging using RFR products: build liquidity in HONIA instruments (deposits, FRNs, swaps) and offer solutions to clients.
4. Update systems and risk procedures: incorporate RFR curves, valuation conventions and accounting/reporting changes.
For treasurers and corporate finance teams
1. Inventory exposures: list all contracts referencing HIBOR and quantify the notional, tenor and fallback language.
2. Decide transition approach: plan whether to amend contracts proactively or rely on fallback triggers; consider cost, legal and operational implications.
3. Test systems and accounting: ensure treasury systems can price and report under alternative benchmarks (HONIA, compounded HONIA) and that accounting/hedge accounting treatments are maintained.
4. Communicate with stakeholders: inform lenders, counterparties and auditors of any planned changes.
For investors and asset managers
1. Reprice instruments: when assessing FRNs, bonds and derivatives, incorporate the correct HIBOR or HONIA curves and any expected spread adjustments.
2. Monitor benchmark reform developments: follow HKMA guidance and market conventions to avoid valuation surprises.
3. Ensure disclosures: update fund documentation and investor materials to reflect benchmark exposures and potential transition risks.
Checklist before entering or amending HIBOR-linked contracts
– Is there explicit fallback language? If so, does it reference HONIA or a compounded overnight RFR and state a transparent spread adjustment?
– Which HIBOR tenor does the product use, and how often does it reset?
– Is there operational capability to handle the chosen reference rate (systems, accounting, hedging)?
– What are the liquidity and market depth for hedges and substitutes (HONIA swaps, FRNs)?
– Are counterparty credit and legal risks addressed if the benchmar k changes?
Mitigants if you rely on HIBOR
– Negotiate strong fallback provisions tied to HONIA or a recognized RFR plus clearly defined spread adjustment methodology.
– Use caps/collars to limit exposure to short-term spikes.
– Hedge exposures using swaps or other derivatives referencing HONIA once market liquidity allows.
– Diversify funding sources and maintain contingency liquidity buffers.
Frequently asked questions (short)
– Is HIBOR the same as LIBOR? No. Both are interbank reference rates but differ by currency and panel; LIBOR was a globally used benchmark that has been phased out after manipulation scandals and regulatory reform. HIBOR is Hong Kong’s interbank offered rate.
– Will HIBOR disappear? As of recent benchmark reform initiatives, markets are promoting HONIA as the HKD risk-free reference rate. HIBOR continues to exist, but market participants are encouraged to adopt HONIA-linked products and include fallbacks.
– How can I hedge HIBOR exposure? Use interest rate swaps, caps or collars referencing the same tenor; consider transitioning to HONIA-based hedges over time.

Final practical priority
1. Inventory all HIBOR exposures. 2. Confirm fallback language and negotiate if weak or absent. 3. Assess suitability of switching to HONIA or fixing rates. 4. Implement hedging and update systems. 5. Communicate with counterparties and advisers.
– Produce a sample checklist or template wording for fallback language (non‑legal draft) you can propose to counterparties.
– Map all HIBOR exposures from a balance-sheet summary you provide and recommend specific hedging approaches.
