TMA Treasury Markets Certificate common mistakes
TMA Treasury Markets Certificate · Understand the traps and how to avoid them.
Treating a spot FX quote as a single price and answering with one number, when the question gives a two-way quote (e.g. 1.2745 / 1.2749) and asks what the client pays to buy the base currency.
Candidates read the pair as 'the rate' and pick whichever number is more memorable or closer to mid, forgetting that the market maker sells the base at the higher side and buys it at the lower side. This is the most frequent arithmetic error in FX questions because the spread is small and the two numbers look interchangeable.
What to do instead
Before computing, write the direction explicitly: 'client buys base → client deals at the offer (right-hand side)'. Practise a fixed drill of ten two-way quotes, each time stating bid, offer, spread in pips and which side a buyer and a seller hit. Always sanity-check that your answer is worse for the client than mid.
Confusing the Treasury bill discount-rate quotation with a true yield, and reporting the discount rate as the return on investment.
Money-market instruments are quoted on a discount basis over a 360-day year on face value, whereas a yield is calculated on the invested amount over 365 days. Candidates who memorise one formula apply it to both, so the answer is close but wrong, and multiple-choice distractors are built around exactly that gap.
What to do instead
Learn the two formulas side by side and convert between them every time: discount rate = (F − P)/F × 360/t; yield = (F − P)/P × 365/t. Rehearse the direction of the conversion (yield is always higher than the discount rate for the same bill) and state the day-count convention in your working.
Describing settlement risk as 'credit risk' or 'market risk' in a question that specifically asks about the period between paying away one currency and receiving the other in an FX transaction.
The risk categories overlap in casual usage, and candidates default to the label they learned first. In FX, the exposure exists only because the two legs settle in different time zones, so the counterparty may fail after you have irrevocably paid but before you are paid.
What to do instead
Build a one-line definition for each risk type and anchor settlement risk to 'Herstatt timing / cross-currency leg mismatch'. When a question mentions time zones, value dates, or CLS, the answer is settlement risk unless the question explicitly asks about pre-settlement exposure.
Applying the FX Global Code as if it were a binding regulation with statutory penalties, and answering that a breach is a regulatory offence.
Candidates conflate the Code with conduct rules issued by regulators. The Code is a voluntary set of global principles, given effect through adherence, statements of commitment, and incorporation into market documentation and local rules, not through direct enforcement by a global regulator.
What to do instead
Memorise the framing: 'voluntary, principles-based, adopted through public statements of commitment and referenced in documentation and local regulation'. When a question asks about consequences, look for reputational and commercial consequences and local-law overlay, not a global sanction.
Mixing up the roles of the front office, treasury operations and the middle office when a scenario asks who should confirm a deal or independently revalue a position.
In small institutions one person may cover several functions, so candidates answer from their own workplace rather than from the control model the exam tests. The segregation-of-duties principle is what the question is really probing.
What to do instead
Learn a three-column map: dealing/execution (front), confirmation, settlement and reconciliation (operations), independent valuation, limit monitoring and P&L validation (middle). For any scenario, ask 'who did the deal?' and assign the control to anyone else.
Treating a forward FX rate as spot plus the full interest rate differential in percentage terms, rather than applying the differential pro rata over the forward period.
Candidates remember 'forward points reflect interest rate differentials' and then add the annual differential directly to spot, ignoring the fraction of the year. The resulting number is wildly out, but the method looks right.
What to do instead
Always write the covered interest parity formula with the day count explicit: F = S × (1 + r_quote × t/B) / (1 + r_base × t/B). Compute the points, then check the sign: the currency with the higher interest rate trades at a forward discount.
Answering questions about last look, pre-hedging or information sharing with a blanket 'prohibited' or 'always permitted' verdict instead of the conditional test the Code applies.
Candidates look for a simple rule to memorise, but the Code sets principles that depend on disclosure, client consent and whether the practice is used to manage risk or to exploit information. A blanket answer ignores the conditions the question is testing.
What to do instead
For each practice, memorise the three-part test: is it disclosed, is it consistent with the client's interest and any agreement, and is the data used only for the stated purpose? Answer with the conditional outcome and name the condition.
Reading a yield curve question as a single-point calculation and ignoring the shape of the curve when asked about carry, roll-down or the outcome of a steepener/flattener.
Candidates focus on the arithmetic of one tenor and forget that a position's return depends on movement along the curve as time passes. The question often supplies two tenors precisely to test roll-down.
What to do instead
Draw the two relevant points of the curve before answering. State the direction of the expected move, then the effect on the position: a steepener gains if the spread widens, and roll-down is positive when the curve is upward sloping and the bond rolls to a lower yield.
Ignoring the value date and holiday calendars when a question asks when an FX trade settles, and defaulting to T+2 calendar days.
Spot FX convention is T+2 business days in the relevant currency centres, but candidates count calendar days or forget that a holiday in either centre pushes settlement out. Some pairs, such as USD/CAD, conventionally settle T+1.
What to do instead
Check three things every time: the conventional tenor for the pair, business days in both currency centres, and the modified-following convention for fixing dates. Learn the standard exceptions (USD/CAD T+1, month-end rules) as a short list.
Answering ethics and conduct scenarios by choosing the option that protects the bank's revenue or the client relationship, rather than the option that satisfies the market-conduct principle being tested.
Candidates with commercial instincts read the scenario as a business judgement call, and the 'reasonable-sounding' distractor is written to reward that instinct. Exam scenarios are designed so that the correct answer is the one that preserves market integrity and discloses conflicts.
What to do instead
Use a fixed decision sequence: identify the conflict, ask whether the client has been told and has consented, ask whether the action would survive public disclosure, then choose. Rehearse the TMA conduct themes (integrity, confidentiality, conflicts of interest, market abuse) against short scenarios until the sequence is automatic.
