International Equity Hedge Over the 60/40
Geographic diversification beats bond hedging over multi-decade horizons.
The traditional 60% stocks / 40% bonds portfolio assumes bonds reliably hedge equity drawdowns. Recent research Nakisa cites argues this is only true when measured monthly. Measured in 10-year blocks, bonds and equities are far more correlated, especially during inflationary regimes — both cratered in 2022 because inflation is toxic to both.
The alternative: hedge equities with international equities, not bonds. Currency moves provide a natural hedge — if your domestic currency devalues during a domestic shock, foreign holdings translate back into more units of your home currency. A 50/50 domestic/international split outperformed 60/40 on terminal wealth, ruin probability, and retirement income in the cited paper's bootstrap Monte Carlo simulation.
Nakisa frames this as foundational: it overturns the premise underlying target-date funds, robo-advisors, and most workplace pensions.
- Bond-equity correlation depends on the measurement window — short-term decorrelation, long-term co-movement.
- Inflation is toxic to both stocks and bonds, breaking the 60/40 hedge exactly when needed.
- Currency devaluation provides a natural hedge — foreign equities translate to more domestic units when home currency weakens.
- Geographic diversification beats asset-class diversification over multi-decade horizons.
- Default options optimise for behaviour (keeping investors in) not for returns.
- Audit your current default allocationCheck what your workplace pension, ISA default, or robo-advisor actually holds. Most will be 60/40 or a glide path toward it.
- Calculate domestic vs international splitAim for ~50/50 if you're in a large market like the US, or tilt more toward international if you're in a smaller market like the UK.
- Replace bond allocation with international equityWhere the 60/40 would hold 40% bonds, hold 40% international equity instead. Use broad index ETFs (e.g. VWRL, VXUS).WarningThis dials up short-term volatility — make sure your behaviour can handle it before changing allocation.
- Add a tactical bond sleeve only for known liabilitiesBonds re-enter the portfolio for cash-flow matching (specific liabilities, ladder during danger zone) — not as a strategic hedge.
- Rebalance annuallyDrift between domestic and international will accumulate. An annual rebalance preserves the hedging ratio.Pro tipUse new contributions to rebalance before selling — it's tax-efficient.
Both stocks and bonds fell sharply in 2022 because the trigger was inflation. 60/40 holders had no hedge.
When sterling weakens during a UK-specific shock, US-denominated holdings convert back to more pounds — a built-in cushion.
Daniel cites research showing 99% of NEST members sit in the default fund; modelling 60/40 vs 80/20 showed only 1 of 9 scenarios where 60/40 won, with bull-market gaps of £15k/year retirement income.
Nakisa cites a recent academic paper that ran bootstrap Monte Carlo simulations on long-block returns rather than monthly returns — exposing that the bond-equity correlation that looks low monthly becomes high over decades. He notes he was 'really excited about it because I like things that kind of contradict what I believe' — his prior was the 60/40 paradigm.
