The actuary's specialties, in detail

The profession's founding field: design, pricing and valuation of individual and group life insurance, major medical, personal accident and health insurance, under the LISF (Insurance and Surety Institutions Law) and the CUSF (Single Insurance and Surety Circular).

Auto, homeowners, fire, liability, marine, agricultural and catastrophe risks. The uncertainty lies in how many claims will occur, how large they will be and how long they will take to pay.

The line that guarantees performance of an obligation. The actuary quantifies the risk that a principal defaults, values the recovery collateral and sets up the surety company's technical reserves.

Insurance for insurers. It designs how risk is transferred to protect the balance sheet against extraordinary losses and to release solvency capital.

The actuary who invests with the liabilities in mind: matching, immunization, hedging derivatives and portfolio construction under the CNSF and CONSAR (National Retirement Savings Commission) regimes.

The enterprise-wide view of risk: the actuary aggregates all risks into a capital measure, sets risk appetite with the board and verifies through stress tests that the institution stays within it.

The actuary who measures the risk of nonpayment: builds origination models, estimates PD, LGD and EAD and calculates reserves and capital under the CNBV (National Banking and Securities Commission), IFRS 9 and Basel.

Valuation of private pension plans, projection of Afore accounts, life annuities and social security finance, in one of the most in-demand fields since the 2020 reform.

The actuary applied to human resources: translates benefits, compensation and headcount decisions into their long-term cost and risk, within the framework of the LFT (Federal Labor Law) and the LISR (Income Tax Law).

The actuary who masters programming combines statistical rigor with data engineering, and brings the risk judgment, interpretability and governance that a production model needs.

Statistical and machine learning models to anticipate claims, lapses and fraud, and to make evidence-based decisions in pricing, underwriting and claims.

Data science in the service of profitable portfolio growth: the actuary brings a value and risk perspective to commercial decisions.

The public sector employs actuaries to supervise the financial system, value the government's large liabilities and design pension and social security policy.

Independent practices and global firms that provide specialized actuarial services to companies, insurers and governments. It is also the natural route to professional entrepreneurship.
