An overview and comparison of the principal asset classes — their characteristics, historical performance patterns, risk profiles, and behaviour across different market conditions.

The following table summarises approximate characteristics based on long-run historical data. All figures are indicative and will vary materially by time period, geography, and instrument selection.
| Asset Class | Approx. Annualised Return (30-yr) | Volatility Profile | Liquidity | Inflation Sensitivity | Typical Role in Portfolio |
|---|---|---|---|---|---|
| Global Equities | 7% – 10% | High | High | Moderate positive (long run) | Growth, compounding |
| Investment-Grade Bonds | 3% – 5% | Low–Mid | High | Negative (real value erosion) | Stability, income, diversification |
| High-Yield Bonds | 5% – 7% | Medium | Medium | Mixed | Income, credit exposure |
| Commodities (broad) | 2% – 5% | High | Medium–High | Strong positive | Inflation hedge, diversification |
| Gold | 4% – 6% | Medium | High | Positive (store of value) | Hedge, tail-risk protection |
| Real Estate (listed REITs) | 7% – 9% | Medium–High | High (listed) | Moderate positive | Income, inflation sensitivity |
| Private Equity | 10% – 15%* | High (smoothed) | Very Low | Variable by sector | Return enhancement, illiquidity premium |
| Infrastructure | 5% – 8% | Low | Low (private) | Positive (contractual linkage) | Stable income, inflation protection |
| Cash & Short-Term Fixed | 1% – 3% | Very Low | Very High | Negative (real terms) | Capital preservation, liquidity buffer |

Equities represent ownership stakes in businesses and have historically delivered the highest long-run returns among liquid asset classes, compensating holders for accepting the highest short-run volatility. The equity risk premium — the excess return demanded by investors over risk-free rates — is the central variable in equity valuation and has historically ranged from 3% to 6% in developed markets.
Global equity markets are not homogeneous. The MSCI World index, dominated by US mega-cap technology, behaves quite differently from MSCI Emerging Markets, which carries currency risk, political risk, and structural economic exposure. Sector composition drives meaningful performance divergence even within the same country index.
Bonds are contractual instruments through which borrowers — governments, municipalities, and corporations — obtain capital from lenders in exchange for periodic interest payments and principal repayment at maturity. The fixed income universe is larger by outstanding value than global equity markets, encompassing everything from overnight interbank deposits to 100-year sovereign bonds.
The interest rate environment is the dominant driver of fixed income valuation. Bond prices and yields move inversely: when rates rise, existing bonds become less attractive and their prices fall. The degree of this price sensitivity is captured by duration — a bond maturing in 30 years will experience a much larger price swing in response to a given rate change than one maturing in 2 years.
The yield curve — the relationship between interest rates and maturities — is one of the most closely watched leading indicators in macroeconomics. An inverted yield curve (short-term rates higher than long-term) has historically preceded recessions in the US economy by 12–24 months.
Crude oil, natural gas, and refined products are priced in global spot and futures markets, shaped by OPEC production decisions, geopolitical events, seasonal demand, and the secular shift toward renewable energy sources. Energy price volatility is among the highest of any commodity complex.
Gold serves a dual role as both an industrial input and a financial safe-haven asset. Its price is inversely correlated with real interest rates and the US dollar. During periods of financial stress or currency debasement concern, gold has historically appreciated in nominal terms, making it a common portfolio hedge component.
Wheat, corn, soybeans, and soft commodities (coffee, cocoa, cotton) are traded on futures exchanges and are driven by a complex of weather events, planting cycles, transportation logistics, and geopolitical disruptions to supply routes. Agricultural commodity prices have significant humanitarian implications as inputs to global food supply.
Understanding risk categories is foundational to understanding why asset prices behave as they do.
Risk arising from broad market movements that affect all assets. Cannot be eliminated through diversification. Measured by beta relative to a market index. Includes equity risk premium, interest rate risk, and currency risk.
The risk that a specific borrower defaults on their obligations. Quantified through credit ratings and expressed in market prices through credit spreads — the additional yield demanded above a risk-free rate for exposure to a given borrower.
The risk of being unable to transact in an asset at a fair price within a reasonable timeframe. Liquidity risk commands a premium — less liquid assets typically offer higher expected returns as compensation for the constraint they impose on portfolio management.
For cross-border investments, exchange rate movements between the base currency and the investment currency add a layer of return volatility. Currency hedging instruments exist but carry costs that reduce net expected returns from foreign exposures.
Changes in government policy, taxation frameworks, ownership rights, or regulatory requirements can materially impair the value of investments. This risk is particularly relevant in emerging markets and sectors subject to intensive regulation.
Low-probability, high-severity events that standard risk models tend to underestimate. Historical examples include the 2008 financial crisis, the COVID-19 pandemic market dislocation, and the 1998 LTCM crisis. Portfolio construction approaches addressing tail risk typically involve options strategies or assets with low-to-negative crisis correlation.
