Risk Parity
An investment approach that allocates capital based on equalising risk contribution across asset classes rather than dollar amounts — using leverage on bonds to match equity volatility, creating large funds that must mechanically rebalance during market stress.
The macro regime is unambiguously STAGFLATION DEEPENING, with the activation of 'Operation Epic Fury' representing a genuine geopolitical regime break that has moved the Hormuz risk from tail to base case. The dominant market narrative for the next 2-6 weeks is the US-Iran military confrontation: Tr…
What Is Risk Parity?
Risk parity is a portfolio construction approach that allocates capital so that each asset class contributes equally to total portfolio risk (measured by volatility), rather than allocating equal dollars. Since bonds are much less volatile than equities, achieving equal risk contribution requires leveraging the bond allocation significantly.
Traditional 60/40 portfolio: 60% equities, 40% bonds. But equities contribute ~90% of total risk because they are 3–4× more volatile.
Risk parity response: Lever up bonds to roughly 2–3× to bring their risk contribution closer to equities'. This creates a more "balanced" risk portfolio across regimes.
Bridgewater's All Weather
The most famous risk parity fund is Bridgewater's All Weather strategy (~$80B AUM), pioneered by Ray Dalio. It is designed to perform across all economic environments — growth, recession, inflation, deflation — by diversifying across assets that perform well in each environment:
- Equities → growth
- Bonds → recession/deflation
- Gold and commodities → inflation
- Inflation-linked bonds → stagflation
The Problem: 2022
Risk parity strategies performed disastrously in 2022 because bonds and equities became positively correlated (both fell simultaneously) — the core assumption underpinning risk parity (that bonds hedge equity losses) broke down. The Bridgewater All Weather strategy reportedly lost ~20% in 2022. Leveraged bond positions amplified what would have been moderate losses.
Mechanical Rebalancing as Market Force
Risk parity funds must continuously rebalance to maintain target risk allocations. When volatility spikes:
- Portfolio volatility rises above target
- Fund must reduce all positions to bring risk back down
- This pro-cyclical selling amplifies market moves
During the March 2020 COVID crash, risk parity deleveraging was widely cited as an amplifier of the equity selloff.
What to Watch
- Bond-equity correlation: Negative correlation = risk parity works; positive correlation = risk parity is a risk
- VIX spikes: Trigger mechanical deleveraging by risk parity funds
- Bond volatility (MOVE index): High bond vol → risk parity reduces bond exposure → sells Treasuries → higher yields
