Quantifying the geopolitical conflict's impact on BTC mainly involves transforming "news sentiment" into "measurable indicators." Professional institutions typically adopt a three-layer framework of "macro index + market data + econometric models." You can focus on the first two layers to guide practical trading.

1. Macro Layer: Use the GPR Index to Replace "Feelings"

Don't judge based on the sensationalism of news headlines. Use the geopolitical risk index as an objective measure. This index is derived from news text analysis; a higher value indicates greater risk.

Qualitative Application: When the index exceeds 150 (high range), BTC volatility usually amplifies significantly.

Quantitative Application: For each standard deviation increase in GPR, BTC returns tend to decline, and volatility rises. Threat-related risks have a more pronounced impact on price than operational risks.

2. Market Layer: Track the Real Response of Capital

Macro indices are lagging indicators; they should be cross-verified with the following three types of real-time market data:

Asset Correlation: Calculate the rolling correlation coefficient between BTC and the S&P 500. If the correlation remains above 0.6, it indicates BTC is acting as a "risk asset" moving in tandem with US stocks. This characteristic is common in the early stages of conflict.

Volatility and Sentiment: Monitor skewness and implied volatility in derivatives markets. During panic, implied volatility spikes, and decreasing skewness indicates the market is pricing in "significant downside tail risk."

On-Chain Demand: Observe OTC USDT trading volume and premiums in conflict zones or sanctioned countries. A surge in trading volume coupled with positive premiums is a strong signal of genuine safe-haven or payment demand.

3. Model Layer: Causal Inference from an Academic Perspective

This is the underlying logic used by institutions for backtesting and forecasting; understanding it is sufficient.

GARCH-MIDAS Model: Incorporates the geopolitical risk index as a low-frequency variable into a high-frequency BTC volatility model. The conclusion is that it significantly improves BTC volatility prediction.

Quantile Regression: Used to assess how the impact of geopolitical risk varies under different market extremities (e.g., sharp decline vs. sideways movement).

💡 Practical Decision Checklist

Based on the "US-Iran conflict," the quantification steps are as follows:

Check the Index: Confirm whether the current GPR is at a 12-month high.

Observe Correlation: Calculate the correlation between BTC and the Nasdaq. If highly positive, operate under the "risk asset" logic (to prevent declines); if decoupled and on-chain premiums exist, operate under the "safe-haven asset" logic (buying the dip).

Set Levels: Refer to historical maximum drawdowns of BTC under similar GPR levels (e.g., -12% to -18%) to establish reasonable stop-loss or position-increasing zones.

Conclusion: Geopolitical conflicts are not simply "bullish/bearish" signals but act as volatility amplifiers. The core purpose of quant analysis is to determine whether they amplify BTC's "risk attribute" or "safe-haven attribute," thereby guiding whether to reduce positions to prevent losses or to accumulate on dips.
