Your Risk Budget Drifted? Fix It Before Losses Grow
Realized vol: 12.8%. Target: 12.0%. Breach: 0.8 percentage points. The correlation shift changes the risk budget math.

Weight Drift Breach in Equity Sleeve Triggers Rebalance
Equity 46%, Bond 32%, Commodity 22%. Realized vol: 12.8%. Target: 12.0%. Breach: 0.8 percentage points. Breach condition: equity drift of 6 percentage points beyond target. Trigger met. Equity-bond correlation: +0.25 — above the +0.25 threshold. Rebalance action: New target weights Equity 40%, Bond 40%, Commodity 20%.
Current weights guide the immediate risk-budget recalibration. The risk-budget framework notes that the equity sleeve drives the majority of volatility, shaping the path of the reallocation. To learn more on mis-sizing risk in RP, see Wrong Position Size? Your Risk Is Off Balance.
| Sleeve | Weight | Sharpe | Volatility % | Max Drawdown % |
|---|---|---|---|---|
| Equity | 46% | 0.75 | 18.0 | 28 |
| Bond | 32% | 0.60 | 8.0 | 9 |
| Commodity | 22% | 0.50 | 22.0 | 26 |
Risk Budget Mechanism Under Drift
Current weights: Equity 40%, Bond 40%, Commodity 20%. Realized vol: 11.4%. Target: 12.0%. Breach: 0.0 percentage points. Breach condition: none. Trigger met: no. Rebalance action: hold; New target weights Equity 40%, Bond 40%, Commodity 20%.
The allocation math shows the risk-budget contributions by each sleeve remain balanced at the current target, but a drift in equity weight has already prompted a threshold breach in prior periods and informs the upcoming adjustment.

Historical Pattern with Equity Alignment in RP Context
Current weights: Equity 40%, Bond 40%, Commodity 20%. Realized vol: 11.2%. Target: 12.0%. Breach: 0.0 percentage points. Breach condition: none. Trigger: hold. Rebalance action: maintain Equity 40%, Bond 40%, Commodity 20%.
In prior cycles, reducing equity exposure toward the 40/40/20 configuration tends to reduce equity-driven volatility contributions and stabilizes drawdown dispersion across sleeves. The factor-overlap context shows that when risk budgets align with the RP framework, diversification benefits are realized, reinforcing the 40/40/20 stance. See Factor Overlap Risk? Your Diversification Is Fake.
Market Signal and Correlation Regime
Current weights: Equity 40%, Bond 40%, Commodity 20%. Realized vol: 11.0%. Target: 12.0%. Breach: 0.0 percentage points. Breach condition: none. Trigger: hold. Rebalance action: maintain Equity 40%, Bond 40%, Commodity 20%.
Under rising-rate and imperfect hedging conditions, correlation shifts alter risk-budget allocations. The correlation data mandates tracking equity-bond and equity-commodity interactions to preserve RP risk parity integrity. For recession-timed adjustments, see Enter Before Recession?

| Sleeve | Weight | Sharpe | Volatility % | Max Drawdown % |
|---|---|---|---|---|
| Equity | 40% | 0.74 | 18.0 | 28 |
| Bond | 40% | 0.60 | 8.0 | 9 |
| Commodity | 20% | 0.50 | 22.0 | 26 |
Final Allocation and Rebalance Plan
Current weights: Equity 40%, Bond 40%, Commodity 20%. Realized vol: 11.0%. Target: 12.0%. Breach: 0.0 percentage points. Breach condition: none. Trigger: hold. Rebalance action: prepare for reallocation if a 0.5pp breach occurs. New target weights: Equity 34%, Bond 46%, Commodity 20%.
You implement the reallocation by shifting 6 percentage points from Equity to Bond, maintaining Commodity at 20%. This tilt reduces equity exposure while increasing the ballast provided by the bond sleeve. The risk-budget share now prioritizes Bond while preserving Diversification.

FAQ
What causes risk drift when Equity sits at 46% and correlation is +0.25?
Risk drift is driven by realized vol exceeding the target and by correlation shifts that alter risk budgets. Equity 46%, Bond 32%, Commodity 22%, correlation +0.25.
This breaches the threshold and triggers a rebalancing to restore Risk Parity Portfolio construction. Source: High-Authority Source (arxiv.org).
How often should I recalibrate Risk Parity Portfolio given the 0.5pp breach threshold?
Recalibration triggers when a breach crosses 0.5 percentage points; The breach triggers a deterministic rebalancing to the target configuration. Equity 34%, Bond 46%, Commodity 20%.
This policy maintains RP construction by rebalancing on breach thresholds and reinforces the required threshold-driven cadence. Source: High-Authority Source (arxiv.org).
Executive Rebalance Roadmap
Final verdict: The Risk Budget Drift breaches the 0.5pp threshold and the correlation regime (+0.25) necessitates a deterministic reallocation to Equity 34%, Bond 46%, Commodity 20% to align with RP construction. This 34/46/20 target is the policy stance moving forward.
Rebalancing steps: (1) Monitor for a 0.5pp breach and verify the correlation remains at or above +0.25; (2) Execute a 6 percentage-point shift from Equity to Bond to reach Equity 34%, Bond 46%, Commodity 20% and maintain 100% total.
