What assets matter when markets are volatile

How does market volatility affect the mix of assets in your investment portfolio?

5 August 2025  │  Ross Finlayson

Overview

Periods of high volatility can cause equities, bonds and other assets to move unpredictably. Cash can reduce short-term fluctuations but may lose purchasing power to inflation.

What to consider

Bonds can provide income, yet their prices can fall when interest rates rise. Gold and alternative assets also fluctuate and may not offset losses during every crisis.

Key takeaways

The right mix depends on time horizon, liquidity needs and capacity for losses. Rebalancing and diversification are tools, not guarantees.

Different assets, different risks

Equities, government bonds, corporate credit, cash and commodities respond to economic shocks in different ways. In a recession, high-quality bonds may help offset equity weakness; during an inflation shock, both can fall. Historical relationships are not guarantees.

Liquidity matters

Assets that look stable in normal times may be difficult to sell during stress. Consider bid-ask spreads, fund structure, duration and credit quality. A cash reserve for near-term expenses can reduce the need to sell risk assets at an unfavourable time.

Rebalancing without prediction

Rather than guessing the next market move, investors can set target allocations and review them periodically. Rebalancing controls exposure but can involve transaction costs and taxes. The right mix depends on the time horizon and tolerance for losses.

Questions to revisit

Before making a decision, ask what could go wrong, which assumptions must hold and how the position would affect your portfolio if markets move against you. Compare the potential benefits with the costs, complexity and liquidity constraints. A decision that fits your goals and time horizon is more useful than trying to predict every market movement.
