Mean-Variance Optimal Portfolios under State-dependent Preferences

Motivated by insurance applications, we propose a new approach for the validation of real-world economic scenarios. This approach is based on the statistical test developed by Chevyrev and Oberhauser (2022) and relies on the notions of signature and maximum mean distance. This test allows to check whether two samples of stochastic processes paths come from the same distribution. Our contribution is to apply this test to a variety of stochastic processes exhibiting different pathwise properties (Hölder regularity, autocorrelation, and regime switches) and which are relevant for the modelling of stock prices and stock volatility as well as of inflation in view of actuarial applications.

In this webinar hosted by Banking Virtual Forum (BVF) held on 28 October 2025, the speakers will provide an overview of the key changes to the capital requirements for banks under finalized Basel III – their background, implications and considerations going forward. Speakers: Monique de Waal and Stephen Scott Moderator: Michael Tichareva

ASTIN's Working Party on IFRS 17 Actuarial Best Practices has now accomplished its target objectives. The report with the results of the study is published in the IAA's website Access is restricted to ASTIN members. The ASTIN webinar will present the results of the study performed by this Working Party. With this working party, we hope to contribute to a better understanding of how the (re)insurance industry, from the perspective of actuaries working in non-life (re)insurance, applies the IFRS 17 Standard in practice and which should be best practices to consider. It will make this project worth it if the responses and conclusions in this report aid in validating current approaches and serve as basis for validation of future decisions. As a departing note, we would like to show our appreciation for all the respondents to this survey, for the underlying (re)insurance entities and particularly for the actuaries who have taken their time to provide us with the responses. We also thank all the members of the Working Party for their efforts and personal time dispensed to prepare the survey, promote it worldwide and disclose this report and the upcoming presentation of results

In this concluding session of our three-part series, our speakers will explore recent developments in insurance solvency regulations across Asia, focusing on Japan’s Economic Value-Based Solvency Regulation (ESR) and Korea’s K-ICS. We will examine the design, implementation status, and key challenges of each framework. In Japan, preparations are underway for the implementation of ESR in the fiscal year ending March 2026, with key issues including strengthening governance, managing interest rate risk, and enhancing disclosure practices. In contrast, Korea has already adopted K-ICS, facing practical challenges such as alignment with IFRS 17 and disparities in company readiness. The session will also discuss how both systems align with international capital standards (ICS) and the strategic responses required from insurers. It will provide practical insights for industry professionals navigating this period of regulatory transition.
