Yield curve extrapolation: work in progress 

A highly accessible overview of the current state of play in the technically challenging and increasingly contentious topic of yield curve extrapolation.

 2013 Solvency II: Where did it all go so badly wrong?

Solvency II was not so long ago hailed as the emerging ‘gold standard’ for setting life insurance firms’ regulatory capital, but now bears a closer resemblance to a slow motion train wreck.In this note I highlight the five sources of trouble that have de-railed the project and speculate on what – if anything – might be done to avoid the same errors elsewhere where capital regulation is still under development.


to 2012

Over a 16-year period I have written a large number of blogs, technical notes and research reports for Barrie & Hibbert’s research library covering topics such as:

  • Portfolio risk measurement & management
  • Asset and liability valuation and management
  • Analysis of the pricing and risks of various savings and structured products
  • Stochastic asset models and their calibration
  • Yield curve extrapolation and the analysis of liquidity premia in financial asset prices.

For example, the widely-quoted 2001 research report co-authored with Philip Mowbray and Craig Turnbull: A Stochastic Asset Model & Calibration for Long-Term Financial Planning Purposes
