HKSI Paper 7Study Notes

Common pitfall

The global FX market is the most liquid market but it is an OTC market, not exchange-traded, and it is not uniformly regulated by central banks — one of the most common reversed-direction traps.

Key numbers

Commercial paper maturity is usually under 270 days; the line between money and capital markets is one year of original issue maturity, not remaining maturity.

Common pitfall

Technology and globalisation make information near-instant, which actually limits or eliminates traditional arbitrage opportunities rather than expanding them — one of the most common reversed-direction traps.

Easy to confuse

Depth is about the order quantity at specific price levels, while tightness/breadth is about the size of the bid-ask spread — the two are often swapped as a trap.

Common pitfall

In indirect financing, depositors bear the intermediary own credit risk, not the final borrower default risk — losses are first absorbed by the intermediary capital.

Easy to confuse

The business sector (firms and financial institutions) is overall a net borrower/demander of funds, not the main net supplier of long-term surplus funds — that role is usually played by households.

Easy to confuse

The two phases "expansion to peak" and "peak to contraction" are easily confused: in the former unemployment is still falling and inflation is only starting to rise; in the latter unemployment has fallen below the structural rate and the central bank is already hiking consecutively.

Common pitfall

Demand-pull and cost-push triggers are frequently swapped as distractors — before answering, decide whether the driver is a shift in demand or in supply.

Easy to confuse

The IMF handles exchange rate surveillance and short/medium-term financing, the World Bank handles long-term development loans, the BIS is the "bank for central banks", and the Basel Committee sits under the BIS setting banking standards — these four are frequently swapped as distractors.

Key numbers

The Barings Bank collapse occurred in 1995 — the core lesson is complete separation between front-office trading and back/middle-office settlement, preventing "player and referee".

Key numbers

7.75 is the strong side (triggered when the HKD strengthens, HKMA sells HKD); 7.85 is the weak side (triggered when the HKD weakens, HKMA buys HKD); 7.80 is only the central rate, not an intervention trigger. Do not mix up these three numbers.

Common pitfall

Common error: mistaking a bank selling HKD to the currency board for USD as increasing the Aggregate Balance (it actually decreases it); mistaking HKD rates as rising when the strong-side undertaking is triggered (they actually fall because the Aggregate Balance increases).

Easy to confuse

Common errors: attributing securities/futures market regulation, insurance regulation, MPF regulation or fiscal policy-making to the HKMA; assuming Exchange Fund investment surpluses are paid directly into general government revenue for recurrent spending; assuming the HKMA "delegates" authority to the SFC over the securities industry (they are separate, independent statutory bodies, not a delegation relationship).

High-frequency point

Common errors: listing "providing a fundraising platform", "increasing market liquidity" or "ensuring listed issuers are profitable" as SFC statutory objectives (these are functions of the exchange/market itself; the SFC does not guarantee investment returns); attributing MPF regulation, insurance regulation, monetary policy or mortgage-securitisation business to the SFC.

Key numbers

HK$300m/HK$100m/HK$25m are the capital thresholds of the three tiers; HK$500,000/HK$100,000 are the minimum deposit amounts for restricted licence banks and DTCs. These two sets of numbers are often swapped in exam questions — keep "capital requirement" and "deposit limit" clearly separated.

Common pitfall

Common errors: assuming all authorized institutions must directly participate in RTGS (only licensed banks and restricted licence banks may); assuming RTGS uses batch net settlement; assuming RTGS main purpose is reducing market risk or increasing arbitrage opportunities.

Easy to confuse

Common errors: assuming authorized institutions (e.g. banks) engaging in securities/futures business are exempt from SFC registration (they must register as a "registered institution"; day-to-day supervision still rests mainly with the HKMA); assuming there are only 4 or 5 regulated activity types.

Easy to confuse

Common errors: assuming "professional investor" or "institutional investor" status itself requires an SFC licence (they are typically service recipients, unless they themselves carry on a regulated activity); assuming every entity engaging in regulated-activity business must be licensed with no exceptions (proprietary trading is typically exempt).

Easy to confuse

Common errors: treating "strategic asset reserve" as a statutory Exchange Fund component; assuming the HKMA independently owns the foreign reserves (they are owned by the Government); reversing the logic so that fiscal reserves appear to sit inside foreign reserves (fiscal reserves are actually a component of Exchange Fund assets).

Key numbers

Common errors: mixing up the age thresholds (55 vs 60) and collateral types (property vs policy) of the three programmes; mistaking the Exchange Fund Bills scheme for an HKMC product.

Easy to confuse

Common errors: mistaking profits/salaries tax changes or government spending changes for monetary tools; mistaking lending-rate or reserve-requirement changes for fiscal tools; assuming Hong Kong has a statutory reserve requirement ratio; folding exchange-rate stability into the Article 107 fiscal principles.

Common pitfall

Common errors: listing "raising the reserve requirement ratio" as expansionary (it is actually contractionary); listing "cutting infrastructure funding" as expansionary fiscal policy (it is actually contractionary); listing rising unemployment as a side effect of expansionary fiscal policy.

Common pitfall

A dividend is never a legal promise — any option claiming "shareholders are entitled to a fixed annual dividend" is almost certainly wrong; a fixed dividend is a feature of preference shares or bonds, not ordinary shares.

Easy to confuse

Ordinary vs preference shares is a favourite exam angle on "which one has a fixed dividend" — remember "preference = priority + fixed"; ordinary share dividends always float with profit.

High-frequency point

The single key distinction between a bonus issue and a rights issue is whether shareholders must pay for the new shares. Paying (rights issue) is genuine fundraising; a free distribution (bonus issue) is purely an accounting reclassification from reserves to share capital, with no new cash inflow.

Key numbers

Theoretical ex-bonus price formula: total cum-market value ÷ (cum-shares + bonus shares). The denominator must include the new bonus shares, otherwise the result is overstated.

High-frequency point

To judge "can it raise funds", ask one question: does the money flow to the listed company itself? Equity warrant exercise money goes into the company accounts; derivative warrant settlement money flows only between the investor and the third-party issuer, unrelated to the listed company, so it raises no funds.

Easy to confuse

Private placement and private equity are the most easily confused pair — the distinction is whether the issuing company is already listed: a private placement is an already-listed company issuing new shares to select investors; private equity is an unlisted company raising funds from select investors.

Key numbers

Main Board: 3-year cumulative profit at least HK$80 million, market cap at least HK$500 million; GEM: 2-year operating cash inflow at least HK$30 million, market cap at least HK$150 million. These figures must be memorised — a common judgement and calculation question type.

Common pitfall

For case-calculation questions, note: whether the 3-year cumulative profit reaches HK$80 million is only one requirement — the latest-year and prior-2-year sub-thresholds must also be checked simultaneously.

High-frequency point

The core distinction between an equity warrant and a derivative warrant is the issuer: an equity warrant is issued by the underlying company itself and dilutes its capital on exercise; a derivative warrant is issued by a third-party financial institution and is unrelated to the underlying company’s capital structure. This is the most common trap.

Common pitfall

When expecting a sharp price decline, the correct action is to buy a put warrant or put option (acquiring the right to sell), not to write (sell) a call option — the latter is an obligation, not a right, with an entirely different risk profile.

Key numbers

Leverage ratio = 1 ÷ margin ratio. A 50% margin ratio means 2x leverage; 30% means about 3.33x. Memorise this conversion — leverage-multiple questions are common.

Common pitfall

The denominator for margin return is always the actual own funds invested, not the total trade value — the most common calculation trap. If a question asks for the full net return, borrowing interest and round-trip commission must also be included.

Easy to confuse

Trading and clearing are two separate systems: OTP-C handles order matching, CCASS handles clearing and settlement. The central counterparty for stock options is SEHK Options Clearing House, not HKCC, which handles futures products.

Key numbers

T+2 calculation must skip Saturdays, Sundays, public holidays, and typhoon closure days day by day — never count plain calendar days. The final settlement deadline under continuous net settlement is 3:45pm.

Easy to confuse

A put option is sometimes mistaken for a debt security because it also has an expiry date — the key distinction is that an option holder has a right, not a debt claim, and the writer has no obligation to repay principal or interest.

Key numbers

A zero-coupon bond has a coupon rate of exactly 0% — it is not "fixed" in the fixed-rate sense. Floating rate and variable rate have different reset mechanisms, and exams often set traps around this distinction.

Key numbers

EFB has three tenors — 91/182/364 days. EFN has six standard tenors — 2/3/5/7/10/15 years, shortest 2 years. This is the single most important number set in the whole topic.

Easy to confuse

A semi-official agency without a direct government guarantee often yields more than sovereigns and top supranationals — the absence of a direct guarantee matters. Do not assume "government-related" always means lowest risk.

Common pitfall

CD tenor appears with two different verbatim exam wordings (3mo-3yr / 1mo-5yr) — always answer using the figures given in that specific question, not a single memorised version.

Key numbers

Risk premium = specific security yield − risk-free rate. If the question asks for the "pure credit risk premium", you must further subtract the liquidity premium and tax premium from the total spread — the total spread alone is not the answer.

Easy to confuse

REITs, CDS and ETFs are often mistaken for securitisation products. The test is whether repayment comes directly from an underlying asset pool's cash flow — none of the three qualify.

Common pitfall

Securitisation is not "sell and forget" — if the originator provides recourse or a guarantee, or holds a junior tranche, it still bears contingent-liability and impairment risk.

Key numbers

The Money Lenders Ordinance statutory cap is 48% (from 30 December 2022). At the same 40.5% nominal rate, the higher the compounding frequency the higher the EAR — monthly and daily compounding already breach the cap.

High-frequency point

Always use the exact multiplicative Fisher equation (1+nominal)=(1+real)×(1+inflation). Simple addition/subtraction is only an approximation — if the question asks for an "exact" figure, do not shortcut with addition.

High-frequency point

An inverted curve is a leading indicator of slowdown/recession, not of expansion. This directional trap is tested repeatedly in this topic.

Key numbers

A zero-coupon bond is the only bond type with duration equal to its maturity. The lower the yield, the stronger the convexity effect — the price gain from a rate fall typically exceeds the price loss from an equal rate rise.

Easy to confuse

A rating change only affects an outstanding bond's secondary-market price and the cost of new issuance — it does not change the coupon rate already locked in. Keep the three dimensions (coupon rate / secondary price / new-issue cost) clearly separated as to which changes and which does not.

High-frequency point

Low-risk-tolerance retiree allocation questions are heavily tested: the core answer always centres on government backing, short duration and stable cash flow. Leveraged derivatives and long-dated zero-coupon bonds are always wrong options.

Key numbers

Memorise five figures for the HKD peg: October 1983 (adoption), 7.75 to 7.85 (Convertibility Undertaking band), 2005 (two-way undertaking introduced), 7.80 (note-issuance backing rate) and 100% (reserve backing ratio).

Common pitfall

Remember the order: Bretton Woods (1944, pegged to gold) → Smithsonian (1971, failed rescue) → Plaza (1985, devalued USD) → Jamaica (legitimised floating). The exam commonly scrambles the years or purposes of these four agreements as distractors.

High-frequency point

To decide multiply or divide: check whether USD is the base or quote currency in each pair. If USD is base in one and quote in the other → multiply. If both are quoted as USD/X (USD as base in both) → divide.

High-frequency point

Core logic of interest rate parity: the low-interest currency trades at a forward premium, the high-interest currency at a forward discount, eliminating risk-free arbitrage. Whichever currency has the lower rate is always the one at a forward premium.

Common pitfall

A common trap is scrambling the definitions — calling a swap a standardised exchange contract, saying options bind both sides, or calling forwards standardised exchange-traded agreements. Remember: only the option buyer has a choice; in the other three, both sides must perform.

Easy to confuse

DCASS handles derivatives, CCASS handles cash securities — the initials D and C are the mnemonic. Even though stock options sound securities-adjacent, they always clear through DCASS, not CCASS.

Key numbers

Breakeven formulas to memorise: calls (buyer and seller share the same breakeven) = strike + premium; puts (buyer and seller share the same breakeven) = strike − premium. Max profit and max loss swap between buyer and seller — identify your role before calculating.

Easy to confuse

Selling a put is often mistaken for a bearish trade, but it is actually bullish/neutral — "selling an option to collect premium" means you want it to expire worthless; selling a put means you expect the price to stay above strike, a bullish stance.

Common pitfall

The most common FRA slip-up is forgetting to discount — the settlement amount must be divided by [1 + (reference rate × days/basis)], otherwise the answer overstates by a few thousand HKD. Be able to distinguish the discounted vs undiscounted figures as distractor options.

Common pitfall

The most common comparative-advantage mistake is forgetting to deduct the intermediary fee, or subtracting the two spreads in the wrong order. Follow the steps strictly: calculate both spreads, subtract for total benefit, deduct any fee, then split.

High-frequency point

Hedging an "existing position" is always opposite direction; hedging a "future transaction" is always the same direction — because with a future transaction there is no position yet, the derivative position simply pre-simulates that future trade.

High-frequency point

Rate futures hedge direction mnemonic: "worried rates will rise on a loan → sell futures; worried rates will fall on a deposit → buy futures". Since futures price and rates move inversely, selling futures is a bet on rising rates (falling futures price) — exactly what a worried borrower needs.

Key numbers

A common silver futures trap: the offshore RMB code is SIN, not "SRN" — the exam deliberately uses similar-looking letters to test precise recall.

Common pitfall

Remember: an option buyer never faces a margin call (risk is capped at the premium paid); only the seller (especially naked) must maintain margin. This is a common exam trap — candidates often mistakenly think even buying an out-of-the-money option can trigger a margin call.

Easy to confuse

The risk premium is only an "ex-ante" expected relationship — a high-risk asset can, "ex-post", actually underperform the risk-free rate. Exams commonly set traps around this.

Common pitfall

The ultimate goal of risk management is not to "eliminate" risk, but to keep it within the organisation's risk appetite. "Risk aversion" is a psychological attitude, not one of the four treatment methods — a common source of confusion.

Common pitfall

Standard deviation = square root of variance — never output the variance figure without taking the square root. Standard deviation measures "total risk" and does not fully cover credit or liquidity risk.

Key numbers

The normal distribution empirical rule: μ±1σ≈68%, μ±2σ≈95%, μ±3σ≈99.7% — must be memorised. One-sided tail probability = total tail probability ÷ 2, never answer with the total probability directly.

Key numbers

Modified duration formula: modified duration = Macaulay duration ÷ (1 + yield/coupon frequency); 1 basis point = 0.01%. Yield up means price down, yield down means price up — do not reverse the direction.

Easy to confuse

DVP, novation and mark-to-market all have credit risk control as their core purpose (not market or systemic risk). None of them eliminates market risk — the underlying price volatility still exists.

Easy to confuse

Segregation of duties (front/back office) is a Barings Bank lesson, not a core Enron lesson — the two cases have different root causes, and exams often swap them as a trap.

Key numbers

Memorise the three deposit thresholds (100k / 500k / unrestricted) and that only licensed banks may conduct retail banking; also remember the register of relevant individuals is kept by the HKMA (not the SFC), and HKEX has had no licensing power since 2003 — both are common traps.

Easy to confuse

L&I clearing is often confused with futures / options clearing — L&I products are listed as ETF-structure securities and cleared by HKSCC. Repos are often mistaken for unsecured financing, but they are secured borrowing in economic substance despite being a sale in legal form.

Easy to confuse

Selecting and appointing the fund manager is the sponsor responsibility, often wrongly attributed to the trustee — the trustee only safeguards assets and monitors compliance with the trust deed, and plays no part in appointing the fund manager.

Common pitfall

Advantage/disadvantage questions often mix distractors: "guaranteed CGT exemption", "guaranteed above-benchmark return" and "investors can directly control trades" never appear as correct advantages — they contradict the indirect, discretionary nature of a managed fund.

High-frequency point

Whenever the scenario mentions issuing shares/bonds to raise capital, privatisation, or acquiring a listed company, the answer is almost always a corporate finance adviser, not a fund manager, financial planner or stockbroker — first distinguish a corporate financing need from a personal wealth-management need.

High-frequency point

Remember a corporate finance adviser "arranges" financing rather than "provides" it — options mentioning "lending from its own balance sheet", "engaging advisers on the client behalf", or "discretionary asset management" are common wrong-answer traps.

High-frequency point

The full sequence — assess needs first, advise, then execute trades on authorisation — best fits an IFA; a discount broker has no planning component, and a full-service broker lacks the full assess-then-authorise-execution flow. Questions often test this by describing the role and asking you to identify it.

Easy to confuse

The four-step order (define goals → set strategy → execute → ongoing review) is often scrambled in questions — remember "goals" always comes first; the "dynamic" nature is driven by the client life-cycle change, not market forecasting or industry technology.

Key numbers

Net proceeds depend only on "current market value − current outstanding mortgage balance" — it has no direct relationship to the purchase price, original loan amount, or how much principal has been repaid; questions often mix in these figures to induce a wrong calculation.

Key numbers

Three compound-interest steps: halve the per-period rate → multiply the number of periods → substitute into (1+i)^n. Two steps for the simple nominal rate: total rate = interest / principal → divide by the holding period in years (convert months to years first).
