Inflation-hedging Portfolios in Different Regimes

The unconventional monetary policies implemented in the wake of the subprime crisis and the recent increase in inflation volatility have revived the debate on medium to long-term resurgence of inflation. This paper presents the optimal strategic asset allocation for investors seeking to hedge inflation risk. Using a vector-autoregressive model, we investigate the optimal choice for an investor with a fixed target real return at different horizons, with shortfall probability constraint. We show that the strategic allocation differs sharply across regimes. In a volatile macroeconomic environment, inflation-linked bonds, equities, commodities and real estate play an essential role. In a stable environment (“Great Moderation”), nominal bonds play the most significant role, with equities and commodities. An ambitious investor in terms of required real return should have a larger weighting in risky assets, especially commodities.
