When long-horizon equity portfolios bleed returns through legacy FX hedging rules.
Sector: Family Office – Multi-Generational Portfolios
Asset Class: Global Equities with FX Forward Overlay
Situation Type: Long-horizon equity portfolio with mechanically rolled, full FX hedging policy
Primary Issue: Structural FX hedge drag driven by over-hedging, negative carry, roll leakage, and governance inertia misaligned with portfolio horizon
The Situation
A multi-generational family office holds a globally diversified equity portfolio designed to compound across decades.
FX hedging was introduced as a governance control to reduce reporting-currency volatility. Over time, this evolved into a default policy of fully hedging foreign currency exposure using rolling FX forwards.
On paper, FX risk is “managed.”In practice, the hedge framework imposes a persistent, compounding cost that was never re-underwritten as the portfolio scaled.
The result is return erosion without any deterioration in underlying asset performance.
Why This Scenario Is Common
-
FX hedging introduced as prudence signalling, not an economic tool
-
Binary hedge rules adopted for simplicity and defensibility
-
Rolling forwards treated as operational maintenance
-
Carry and roll costs absorbed without explicit ownership
-
EM currencies hedged reflexively despite poor economics
-
Governance focused on hedge presence, not hedge behaviour
This is structural inertia, not a mistake.
Why It Matters
As the overlay compounds over time:
-
Negative carry quietly erodes long-term returns
-
Roll leakage accumulates through frequent execution
-
FX hedges absorb upside without proportionate drawdown protection
-
EM hedging costs exceed plausible risk reduction
-
Portfolio outcomes diverge from long-term expectations
Value is lost without any increase in portfolio resilience.
How This Is Typically Addressed
-
Maintaining full hedge ratios “for consistency”
-
Treating FX costs as unavoidable overhead
-
Avoiding change to preserve governance optics
-
Deferring action until performance drag becomes visible
These approaches preserve comfort – not outcomes.
