保險業清償能力制度之探討---以歐盟Solvency II為例

譚雅蓁 Unknown Date (has links)
金融服務業的跨業經營讓保險業監理制度面臨新變革,而2008年金融海嘯重創國際金融以及全球經濟更讓金融服務業監理出現更多未可知的變數,歐盟在體解現行保險業清償能力制度(Solvency I)不足下著手於新清償能力制度(Solvency II)之建立,惟透過風險的角度作全面制度的基礎著眼點是否真能適切反映監理需求、達到保護保單持有人的最終目標,並成為帶領保險業駛離本次金融海嘯的諾亞方舟? 本文從歐盟現行保險業清償能力制度談起,逐步進入Solvency II計畫的實質內涵,兼論該制度設計可能存在的問題,並對於新制在未來趨勢上對國際保險業監理所可能造成之影響作初步探討。最後,從歐盟Solvency II計畫的角度出發、反視臺灣現行保險業清償能力監理架構,從而對於未來制度之設計給予相關之建議,並期盼本文能以投石問路之姿,在全球金融籠罩在一片動盪不安的此時,就臺灣保險業清償能力監理制度這一塊,提供另一種可能的思維方向。

引入總體因子之信用計量模型 / The CreditMetrics Model with Macro Factors

吳亞諾, Wu, Ya-No Unknown Date (has links)
在金融海嘯之後, 信用風險的重要性益發為銀行金融業所重視。 為深入探索此議題, 本文以 CreditMetrics(TM) 模型為基底, 設定台灣 458 間上市櫃公司為虛擬資產組合, 做出其資產組合價值分配與資產組合損失分配, 以估量信用風險的大小, 提供銀行業計提資本時一個適當的方向。 在模型上, 本文採納 CreditMetrics(TM) 考量交易對手資產報酬率相關性的優點, 此點使我們交易對手評等的移轉產生相關性, 不致低估信用風險; 並修正其以外部評等機構所提供的無條件移轉矩陣為模型參數的設定, 使用排序普羅比模型 (Ordered Probit Model) 在移轉矩陣上引入總體因子, 搭配 Svensson 四因子模型所估計的放款殖利率, 做出條件情境的的經濟資本, 增加資本計提的準確度。 此外, 為了解總體因子的重要性, 本文將之與評等因子做比較。 實證結果發現, 加入總體因子會對信用風險造成一定程度的衝擊, 銀行業實不宜再以無條件情境做為計提資本的標準。 而在評等與曝險額呈現正相關的條件下, 評等因子的重要性比起總體因子有過之而無不及。 銀行業在計提資本時, 與其費盡心思在模型中納入總體因子, 也許應該先看看評等是否已經納入考量。

匯率風險下壽險業經濟資本之探討 — 以利率變動型年金商品為例 / Discussion on economic capital of life insurance industry under currency risk — a case of interest sensitive annuity policies

邱俊智 Unknown Date (has links)
保險法第146條之4規範國外投資總額最高不得超過各該保險業資金45%,而2014年修正增列保險業依保險法規定投資於國內證券市場上市或上櫃買賣之外幣計價股權或債券憑證之投資金額,可不計入其國外投資限額。且因我國市場長期處於低利環境,壽險業即大量以台幣作為融資貨幣買入國外高利率環境下之標的貨幣進行利差交易,本研究擬以經濟資產模型進行資產與負債之模擬,衡量壽險公司的經濟資本與清償風險。 依據現行壽險公司資金運用決定投資之標的,並以Cox-Ingersoll-Ross (1985)模型模擬國內外短期利率,在無拋補利率平價說下建立匯率模型,以Heston (1993)隨機過程描述資產的變化,並考量壽險公司投資策略決定投資比率,再加入資產之相關性進行模擬;以與壽險公司投資連結之利率變動型年金為商品,加入各項風險因子進行負債價值模擬,諸如死亡率、解約率等因子;資產與負債皆在風險中立測度下以蒙地卡羅法進行模擬10,000次,探討公允價值下壽險公司之清償能力。 而現行清償能力指標為資本適足比率,但此標準下尚無法完整考慮各風險之相關性,本研究除考量資本適足比率中風險資本總額,亦加入經濟資本進行分析,可得以下結果: I.現行RBC風險資本總額介於VaR 99.5%與95%所計算之經濟資本間。 II.當匯率波動度與國外投資比例增加時,經濟資本亦將顯著增加。 III.隨國外債券投資比例增加,風險資本總額增加之幅度亦會加速成長。 IV.利率變動型年金商品宣告利率之擬定將顯著影響公司面臨之違約風險。 / The amendment of Article 146-4 of Insurance Act extended the overseas investment ceiling in 2014 that the International Bond was not included to be counted in overseas investment. Since we have been suffering from the low interest rate for a long time, life insurance industry often uses carry trade to enlarge their earnings. In this paper, the investment targets are chosen on the basis of the current life insurance industry. We simulate the short-term interest rate based on Cox-Ingersoll-Ross (1985) model, establish the exchange rate model by Uncovered Interest Rate Parity, and use Heston (1993) model to simulate stochastic process of assets. Then we consider the life insurance industry’s investment strategy to determine the investment ratio and also import the asset correlation into our models. The interest sensitive annuity policies we used to evaluate the liabilities are linked with life insurance companies’ investment. Some risk factors are also been considered, such as mortality, surrender rate and other factors. Through Monte Carlo simulations by 10,000 times, we analysis the life insurance companies’ solvency under risk neutral measurement by using Risk-Based Capital and Economic Capital. The results show that: I.Risk-Based Capital is between Economic Capital calculated by VaR 99.5% and 95%. II.When the volatility of exchange rate and overseas investment ratio increase, the Economic Capital will also increase significantly. III.With the increase in the proportion of foreign bond investment, the increase in the Risk-Based Capital will accelerate the growth. IV.The declaring interest rate of interest sensitive annuity policy will significantly affect the default risk faced by the life insurance company.
