Global Markets Commentary

Executive Summary

The war or special military operation in Iran could lead to stagflation.

Stagflation represents one of the most challenging macroeconomic environments for investors, combining weak growth with persistent inflation. Traditional portfolio structures such as the 60/40 model tend to underperform, requiring a strategic shift toward real assets, commodities, and pricing-power equities.


Understanding Stagflation

Stagflation occurs when economic growth slows while inflation remains elevated. This creates a policy dilemma, as central banks must balance inflation control with growth support.


Market Implications

Both equities and bonds tend to suffer. Real returns on fixed income decline, while equities face margin pressure and valuation compression.


Strategic Asset Allocation

Investors should increase exposure to commodities such as energy, copper, and gold. Equities should tilt toward value sectors with strong cash flows and pricing power. Fixed income should focus on short-duration and inflation-linked instruments.


Global Opportunity Set

Resource-rich regions such as Latin America, Africa, and Central Asia stand to benefit. Infrastructure and energy investments in ASEAN also provide inflation-linked growth opportunities.


Portfolio Framework

A diversified stagflation-resilient portfolio includes allocations to commodities (10–20%), energy and mining equities (15–25%), global equities (20–30%), fixed income (15–25%), alternatives (10–20%), and liquidity (5–10%).


Key Risks

Key risks include policy errors, prolonged inflation shocks, and geopolitical escalation. Investors should avoid excessive duration and overexposure to growth assets.


Conclusion

Stagflation requires a paradigm shift in portfolio construction. Real assets move to the core of allocation, while diversification across geographies and asset classes becomes essential.
