| Abstract: | 在長期低利率環境下，台灣壽險業因高預定利率保單所帶來的財務壓力，普遍採取大規模海外投資策略，然而幣別錯配與會計評價方式差異已逐步侵蝕其財務穩健。隨著國際財務報導準則第17號（IFRS 17）與新一代清償能力制度（TW-ICS）將於2026年全面實施，壽險業資本結構與資產負債管理策略面臨重大轉型需求。
本研究運用預期效用模型，結合2019年至2025年台灣壽險市場之實證資料，納入國內外資產報酬相關性、負債結構（保單與次順位債）、風險溢酬與幣別差異，並以單位保費之確定等值報酬（certainty equivalent payoff per unit of liability，ce/L）作為最適化目標。研究亦設置違約機率之上限限制，以模擬不同監理情境對保戶效用、資產配置與違約風險之影響，並進行多項敏感度分析。
實證結果顯示：(1) 提升監理強度能顯著提升保戶效用並降低違約風險，且增資措施之效果優於單一限制風險性資產配置；(2) 次順位債之幣別設定對最適配置影響有限，關鍵仍為監理強度與投資策略；(3) 在各種公平條件設定下，嚴格監理均導致較高的 ce/L 與較低的違約機率；(4) 本國市場報酬率下滑或波動度增加將不利於保戶效用，而穩定低波動環境則可增進其利益；(5) 提高保單負債佔比可降低資金成本並提高效用，惟過高比例之次順位債則反而侵蝕保戶效用；(6) 保戶風險厭惡程度升高將壓抑高風險資產配置，而延長保險契約期間則有助於風險分散與回報穩定性。
本研究建議壽險公司應積極充實資本，並強化外幣避險與資產負債管理策略，以因應新制挑戰；同時，監理機關應兼顧資本彈性與風險控管，推動多元籌資工具與監理措施雙軌並進，以維護保戶權益與系統穩定。
Taiwan’s life insurers face rising financial pressure from legacy policies with high guaranteed interest rates amid a prolonged low interest rate environment. With IFRS 17 and the Taiwan Insurance Capital Standard (TW-ICS) set for implementation in 2026, capital structure and asset-liability management (ALM) have become critical. This study applies a utility-based model using 2019–2025 data to evaluate the effects of supervisory interventions on policyholder utility, default risk, and asset allocation. The model incorporates liability structure, risk premiums, asset correlations, and currency differences, optimizing the certainty equivalent payoff per unit of liability (ce/L) under regulatory default constraints.
Results show that stricter supervision improves policyholder utility and reduces default risk, with capital injections more effective than limiting risky investments. The currency of subordinated debt has minimal impact, while regulatory strength and investment strategy are key. Stable markets and longer policy durations further enhance utility. The findings support strengthened capital, improved hedging, and balanced regulatory approaches to ensure insurer stability and policyholder protection. |
