The Solvency Capital Requirement is the risk-sensitive capital a Mexican insurer must hold under the LISF. It can be calculated using the general formula set by the CNSF or, subject to authorisation, with an internal model.

Is the LISF similar to Solvency II?

Yes. The LISF adopts a three-pillar architecture (quantitative requirements, governance and supervision, and transparency/reporting) inspired by the European Solvency II framework, adapted to the Mexican market.

Who supervises the sector?

The Comisión Nacional de Seguros y Fianzas (CNSF), a decentralised body of the Ministry of Finance and Public Credit, which issues the Circular Única de Seguros y Fianzas (CUSF, the single insurance and surety rulebook) with the operational detail.

CNSF / LISF — insurance solvency in Mexico

The CNSF (Mexico's insurance and surety regulator) supervises Mexican insurance under the LISF (the insurance and surety institutions law, 2013), a risk-based solvency regime inspired by Solvency II. Its centrepiece is the solvency capital requirement (RCS), sensitive to risk, which together with technical provisions demands intensive actuarial calculation.

What it requires

RCS — risk-sensitive solvency capital requirement, via general formula or an authorised internal model.
Technical provisions — market-consistent valuation (best estimate + risk margin).
Corporate governance — an integral risk management system and self-assessment.
Regulatory reporting — periodic submission of information to the CNSF (SESA / regulatory reports).

Why it is a compute challenge

As in Solvency II, the RCS and technical provisions require actuarial projections and scenarios across complete portfolios. As granularity and frequency grow, the calculation stops being viable in spreadsheets or rigid batch processes and becomes a data and HPC problem.
