Regulatory Reboot Could Transform Taiwanese Insurers’ Portfolios

Taiwan-based insurers are gearing up for a big overhaul in their regulatory framework. The transition to the Taiwan Insurance Capital Standard (TW-ICS) is slated for January 2026, though some provisions will have a lengthy phase-in period. Over time, the impact on capital-based relative value could lead some insurers to consider transforming their asset allocations.

The shift will happen along with the adoption of a new accounting regime, International Financial Reporting Standard 17 (IFRS 17). TW-ICS is intended to align Taiwan’s regulatory framework with international standards, including Solvency II in Europe as well as Japan and Korea, who have already implemented their version of the ICS. In doing so, the Financial Supervisory Commission hopes to bolster the strength of Taiwan’s insurance sector.

New Calculation for Risk-Based Capital Charges

Under TW-ICS, balance sheets will be treated on a fair-value basis, with both assets and liabilities marked to market where possible. The rules will also usher in a new, more complex, methodology for calculating required capital on different investments. The current calculation is based on rating alone; under TW-ICS, it will also account for the investment’s spread duration, or sensitivity to changes in spreads, and maturity.

For credit risk, there will no longer be a single credit-risk factor. The new rules call for insurers to provide separate factors for default risk and the risk from credit spreads widening in the absence of default, called non-default spread risk, or NDSR. The TW-ICS will sharply increase capital charges (Display), though the interest-rate and NDSR factors will phase in over 15 years to avoid cliff effects.

Assessing the Impact on a Relative Value “Heat Map”

With a few calculations and data points, we can translate the new capital charges into a revised relative value heat map. Default risk can be sourced from a regulatory table, and will vary based on factors including credit rating, type of asset and term to maturity. The NDSR for assets can be calculated with the following function:
