PEARL and currency 2/3: Currency Overlay Attribution: A Practical Guide
18 March 2021
The currency risk factor is considered worthless in the eyes of some investors. It bears no risk premium; hence, it dilutes international returns and therefore needs to be hedged. Others consider currency an asset class in its own right due to the structure in the currency movements. The consensus now seems to be that both are true; it is a tactical asset class that should be strategically hedged.
In our PEARL and currency 2/3 (see 1/3 here) paper Currency Overlay Attribution: A Practical Guide, we take a very detailed look at currencies within performance measurement & attribution.
We describe a consistent and interpretable framework to measure and evaluate the performance of the Investment Decision Process (IDP), in the situation that currency exposures are managed independently from market exposures.
We address the question of how to evaluate the market exposures and currency overlay individually, as well as how to combine the results.
This second, 30 page whitepaper contains the following chapters:
Karnosky and Singer attribution
Currency Overlay IDP
Strategic Currency Overlay Benchmark
Tactical Currency Overlay Allocation
Currency Overlay Implementation
Performance Base for Currency Overlay
Example Currency Overlay Attribution
Combining the Results of the Market and Currency Overlay IDP
Some implications of our Methodology
Extensions: Using Risk Premiums instead of Fully Hedged Returns
When Currency Exposures are not Managed Independently

This blog post explores three approaches to measuring the impact of liabilities on SAA: actuarial simulation, replicating portfolio, and product-based dynamic liability modelling. It also compares the advantages and disadvantages of each approach in terms of accuracy and runtime efficiency, highlighting the benefits of a dynamic liability modelling approach as a fast, flexible, and efficient solution for multi-scenario SAA analyses in a full ALM context.
Creating inflation-resilient portfolios through private assets
Inflation-protected portfolios typically provide a combination of diversification benefits and return improvement. For example, by diversifying to “real assets”, like commodities, direct real estate ...
