When converting a rate quoted as foreign currency per domestic unit into a domestic-per-foreign rate, candidates multiply by the base rate instead of taking its reciprocal, then apply the wrong side of the spread.
Cross-rate arithmetic is usually learned as multiplication (A/B × B/C = A/C), so candidates reflexively multiply even when the required direction calls for inverting one quote first. Under time pressure they skip the step of writing out the unit chain and lose track of which currency sits in the numerator.
What to do instead
Before any calculation, write the target units explicitly (e.g., 'need USD per EUR') and build a chain that cancels currencies. If a quote must be inverted, compute the reciprocal of both bid and offer and swap their order (bid becomes 1/offer, offer becomes 1/bid). Verify by checking the result sits inside the plausible range and that the spread is positive.
Applying the bid rate when a customer is buying the base currency and the offer rate when selling it, producing a consistently favourable price for the client rather than the dealer.
Candidates memorise 'bid is buy, offer is sell' without anchoring it to the dealer's perspective. The market convention is stated from the price-maker's side, so a client buying EUR/USD is dealt at the offer, not the bid.
What to do instead
Adopt one fixed mental rule: the bank always deals on the side that is worse for the client, so the bank buys at bid and sells at offer. Rehearse with a two-line template - client sells base = bank bids = bid rate; client buys base = bank offers = offer rate - and apply it before touching numbers.
Treating a forward rate as a forecast of the future spot rate and answering questions about expected spot movements with the forward points.
The forward rate is derived from the interest rate differential (covered interest parity), not from market expectations. Candidates conflate the two because both are 'future' numbers, and textbooks sometimes discuss expectations alongside forwards.
What to do instead
State the parity identity whenever forward points arise: forward = spot × (1 + i_quote × t)/(1 + i_base × t). If a question asks about expectations, note that uncovered parity is a separate, non-arbitrage-free concept. Check the sign of the points against the interest differential to confirm the direction.
Computing forward points by adding the annual interest differential directly to the spot rate without scaling for the day count and the correct day-count convention (actual/360 vs actual/365).
Candidates compress the formula to spot × (1 + differential) and forget the t/360 or t/365 factor, or they use 365 for a currency whose market convention is 360 (most majors) or vice versa for sterling and some Commonwealth currencies.
What to do instead
Write the full formula with the day-count fraction visible before substituting numbers. Confirm the convention per currency pair (USD, EUR, JPY use actual/360 for money-market rates; GBP uses actual/365). Sanity-check the magnitude: a 1% differential over one month should move the rate by roughly 0.08%, not 1%.
In a currency swap, failing to distinguish the near leg from the far leg when describing cash flows, and netting the two legs into a single figure that hides the rollover exposure.
Swaps are often taught as 'a spot plus a forward', so candidates collapse them into one transaction. In practice the two legs settle on different dates and create separate principal and interest obligations that must be tracked independently.
What to do instead
Draw a two-column timeline: near date and far date, each with principal exchanged and interest paid. State explicitly which currency is received and which is paid on each date, then compute the net only after the gross legs are listed. Remember that at maturity the principal is re-exchanged, not just the interest.
Hedging a known foreign-currency receivable with a forward in the wrong direction, or hedging the exposure with an option and then counting the premium as a separate cost rather than part of the hedge outcome.
Candidates focus on the currency they will receive and sell that currency forward without checking whether the exposure is actually a payable or receivable after netting group cash flows. Option premiums are treated as an afterthought, so the effective rate is misstated.
What to do instead
First map the exposure: currency, amount, direction, and date. A receivable means you will sell foreign currency, so you buy the domestic currency forward (sell foreign forward). For options, compute the effective rate as strike plus or minus premium amortised over the notional, and compare all hedges on the same effective-rate basis.
Confusing transaction, translation, and economic exposure, and applying a transaction hedge to an accounting translation exposure.
The three categories are taught together and all involve foreign currency, so candidates default to 'hedge it with a forward' regardless of which exposure is described. Translation exposure arises from consolidating foreign subsidiaries and is often better addressed with balance-sheet or net-investment hedges.
What to do instead
Classify by source before choosing a tool: transaction exposure is contractual cash flow; translation exposure is accounting restatement of foreign subsidiary assets and liabilities; economic exposure is the effect of rate changes on future competitiveness. Match the instrument to the classification and note that net-investment hedging is the standard treatment for translation.
Assuming a trade settles on the value date implied by T+2 without checking for weekends, holidays in either currency's centre, or the end-of-month convention.
Candidates apply T+2 mechanically and ignore the joint settlement calendar. A Friday trade in a pair where one centre has a Monday holiday rolls to Wednesday, not Tuesday, and month-end trades have special rules.
What to do instead
For every value-date question, list the settlement centres for both currencies and count business days forward from trade date, skipping holidays in either centre. Apply the end-of-month rule: if the spot date would fall in the next month, use the last business day of the current month. State the rule you applied in your answer.
Treating a confirmed SWIFT MT300 or MT320 message as settlement itself rather than as a confirmation, and overlooking the need for matching payment instructions before value date.
Message types and settlement are both 'back office', so candidates blur confirmation with payment. They also assume the counterparty's standing settlement instructions are static and skip verification.
What to do instead
Separate the lifecycle: execution (trade), confirmation (MT300 for FX, MT320 for swaps), settlement instructions (SSIs), and actual funds movement. Always verify SSIs against an independent source before value date, and treat any mismatch between confirmation and SSI as a break requiring escalation, not a clerical detail.
Answering compliance questions by reciting the general principle ('know your customer', 'avoid manipulation') without identifying the specific obligation, threshold, or escalation step the scenario requires.
Ethics and regulatory content is often studied as broad principles, so candidates produce generic statements that do not satisfy scenario-based items asking what the desk should do next, who to notify, or within what timeframe.
What to do instead
For each regulatory topic, memorise the operational chain: detect, document, escalate to the named function (compliance or risk), and record the decision. Anchor answers to the specific obligation in the scenario - for example, a suspicious order pattern triggers an escalation to compliance rather than a quiet conversation with the client - and state the escalation path explicitly.
