Setting a Risk Budget for Global Macro Economics

Which macro forces dominate the risk?

How much portfolio risk comes from rates, growth, inflation, and liquidity—and how much is hidden across apparently different holdings? A macro risk budget starts by describing exposures to economic shocks rather than counting positions. Several instruments can respond to the same real-yield move, demand slowdown, or funding squeeze, so a long holdings list does not necessarily mean diversified risks.

Map exposures before assigning limits

For rates, distinguish sensitivity to short policy expectations from exposure to longer yields and inflation compensation. Growth exposure may appear through expected demand, earnings, or sovereign revenue, while inflation sensitivity depends on pricing power, input costs, indexation, and the horizon involved. Liquidity is another dimension: assets that appear unrelated in calm conditions may become difficult to sell together when funding is scarce.

A factor map is a simplifying model, not a complete causal account. Relationships vary by country, currency, instrument, and regime. Estimate how exposures have behaved across multiple periods, then test whether the sample includes the conditions relevant to the current question. Historical correlations and sensitivities can shift.

Look through labels to concentration

Group exposures by shared drivers and identify where losses could cluster. A portfolio with interest-rate-sensitive bonds, rate-sensitive equity valuations, and leveraged financing can have more duration-related exposure than separate asset-class labels suggest. Credit holdings may also combine spread risk with sensitivity to government yields and liquidity.

Concentration is not limited to a single issuer or market. Similar maturities, reliance on one funding source, a common currency, or exposure to one inflation outcome can create an economic concentration. Record what would be stressed together, including positions that are expected to hedge one another.

• Rate level, curve shape, and inflation compensation
• Growth slowdown, weaker demand, or changing labor conditions
• Credit repricing, reduced market depth, and tighter funding
• Currency and regional exposures that connect multiple holdings

Budget against more than a typical day

Volatility-based estimates can help compare risks, but they are sensitive to the selected window and may understate rare moves or changing correlations. Scenario tests can examine rate repricing, an inflation surprise, recession, or liquidity withdrawal. State the size and timing assumptions; results are conditional illustrations, not maximum possible losses or forecasts.

Also ask whether a position could be reduced when needed. In a stress, bid-ask spreads may widen, financing terms may change, and a hedge may not move as expected. A nominal risk limit that ignores liquidity can overstate the amount of risk that is practically manageable.

Treat the budget as a review discipline

Review the factor map when policy expectations, growth evidence, or funding conditions shift, and explain any change in assumed correlations. The objective is not to eliminate macro uncertainty but to see where one surprise could dominate several positions at once.
