The BlackRock Investment Institute publishes capital market assumptions and asset class return every quarter. Five-year and long-term equilibrium annualised return assumptions are in geometric terms. There are long-term volatility and correlation assumptions. Global equities are represented by the MSCI World ex USA Index in the correlation assumptions; global treasuries by the Barclays Global Aggregate Treasury Index ex US. We break down each asset class into factor exposures and analyse those factors’ historical volatilities and correlations over the past 15 years. Expected return estimates are subject to uncertainty and error. Expected returns for each asset class can be conditional on economic scenarios; in the event a particular scenario comes to pass, actual returns could be significantly higher or lower than forecasted.
