Outline of Final Research Achievements

For the risk management of pension fund there exists new derivatives; Longevity bond and Longevity swap. Longevity bond has theoretical potential to longevity risk management instead of the significant front-end investment cost, which is shown by the numerical simulation. The market popularity of longevity risk management is to longevity swap. The portfolio to minimize longevity risk of pension fund is to include longevity swap to pension portfolio. The optimal portfolio including longevity swap is calculated by minimal martingale probability. The algorithm is derived by local risk minimization. We calculated the optimal portfolio which includes longevity swap or longevity bond in numerical simulation.

Academic Significance and Societal Importance of the Research Achievements

平均寿命の改善が与える年金基金のリスク資金は20~30兆ドルになるとされ、世界的には長寿デリバティブと呼ばれる近年急速に拡大した市場となっている。我が国ではGPIFのポートフォリオばかりではなく民間年金基金も長寿リスクに対する対応を検討しなければならない。本研究は、米国およびヨーロッパの保険企業が拡大させているLongevity derivative の理論的研究を行なった。年金の支払い基金は長寿化による資金不足に直面し、その拡大を回避するための金融イノベーションの派生証券についての研究である。理論的には金利スワップから派生した仕組みであるが、生存率という保険数理に依存するところに特徴がある。
