AMIB Operador de Dinero common mistakes
AMIB Operador de Dinero · Understand the traps and how to avoid them.
Confusing the roles of the Banco Central, the CNV and the Ministry of Economy when a question asks who authorizes, supervises or sets rules for a money-market operation, and selecting the wrong authority.
Candidates memorize institutions in isolation but never map each one to the specific act (authorization, supervision, sanction, rule-making) the question describes, so they default to the most familiar acronym.
What to do instead
Build a one-page matrix with columns 'authorization / ongoing supervision / sanctioning / rule issuance' and place each body (BCRA, CNV, Ministry of Economy, SEGURO DE GARANTÍA type entities) in the correct cells; rehearse by reading a scenario and naming the competent body before checking the answer.
Answering questions about reporting duties and deadlines by guessing a generic 'timely manner' instead of the specific regime (e.g., client identification, transaction reporting, retention periods) that the scenario triggers.
Candidates treat compliance as common sense and skip memorizing the concrete thresholds, deadlines and record-retention periods that the exam tests as discrete facts.
What to do instead
Create flashcards for each reporting obligation with three fields: trigger, recipient authority, and deadline/retention period; drill until each can be recalled without context.
Mixing up money-market instrument features - treating a repo as an outright purchase, a interbank loan as a negotiable security, or confusing a caucion with a placement - when the question hinges on legal ownership transfer or term.
Superficial familiarity with instrument names leads candidates to answer based on the name rather than on the defining economic and legal feature (transfer of ownership, collateral, term, settlement).
What to do instead
For each instrument write a three-line definition covering: who lends/borrows, whether ownership of the asset transfers, and the settlement convention; compare pairs (repo vs. caucion, interbank vs. retail placement) side by side.
Misidentifying the settlement date or the correct settlement cycle when a question gives a trade date and asks when funds or securities must be delivered.
Candidates apply a single remembered convention (e.g., T+2) to every instrument and ignore that money-market instruments often settle same-day or T+1 and that holidays shift the value date.
What to do instead
Tabulate the settlement convention per instrument type and practice with calendar exercises: given trade date plus instrument, compute the value date accounting for business days; verify against the stated convention each time.
Selecting 'eliminate the risk' as the answer for a risk-management question instead of the technique the scenario actually describes (mitigate, transfer, diversify, hedge).
Candidates equate 'managing risk' with 'removing risk' and overlook that money-market practice usually transfers or hedges exposure rather than eliminating it.
What to do instead
Learn the four responses (avoid, reduce, transfer, accept) with a money-market example of each, and in practice questions first label what the described action actually does before choosing the option.
Confusing duration with maturity, or treating a rise in interest rates as increasing the value of a fixed-income position, in sensitivity questions.
Candidates conflate the two concepts and rely on intuition ('longer means more valuable') rather than the inverse price-yield relationship.
What to do instead
Memorize the rule that price moves inversely to yield and that duration measures sensitivity, then practice a set of 'rates up/down, price up/down' items until the direction is automatic before tackling magnitude.
Answering ethics items by choosing the option that maximizes the client's or firm's short-term result rather than the option consistent with integrity and disclosure duties.
Candidates read ethics questions as business-judgment questions and let commercial intuition override the professional-conduct standard being tested.
What to do instead
For every ethics scenario, first identify the duty at stake (conflict of interest, confidentiality, suitability, market integrity) and eliminate any option that hides information or advantages one party unfairly; practice articulating the duty before selecting.
Treating 'know your customer' and suitability as interchangeable, or answering a client-advice question with a product recommendation that ignores the client's stated profile and constraints.
Candidates merge onboarding, suitability and product knowledge into one block and answer whichever concept they recall first rather than the one the question asks about.
What to do instead
Separate the concepts explicitly: KYC = identity and origin of funds; suitability = fit between product and client profile; then practice client scenarios by writing the client's constraints first and only then evaluating the product.
Failing to distinguish a suspicious-transaction report from a threshold-based report, or answering that the institution should confront the client before reporting.
Candidates assume all reporting is mechanical and are unaware that suspicion-based reporting is judgment-driven and that tipping off the client is prohibited.
What to do instead
Memorize the dichotomy (objective/threshold vs. subjective/suspicion), the no-tipping-off rule, and the internal escalation path; rehearse with short scenarios deciding which report applies and whether client contact is permitted.
Misreading the question stem - answering what the instrument is when the stem asks who bears the risk, or answering the regulator when it asks the supervised entity - and thereby choosing a true statement that does not answer the question.
Time pressure and long stems lead candidates to match a familiar keyword to an option without confirming what is being asked.
What to do instead
Underline the interrogative in each stem (who/what/when/which risk) before reading options, and after choosing an option restate the stem with the option inserted to confirm it answers the actual question.
