Bitcoin vs Gold Correlation

0.17 Average Correlation

Bitcoin and Gold were weakly correlated in 2022. With a correlation of 0.17, these assets showed meaningful independence, offering diversification benefits when held together.

For portfolio construction, this weak correlation suggests that combining BTC and XAU could reduce overall portfolio variance. However, correlations can increase during market stress.

Metric	Value
Current (30-day)	0.36
Average (full period)	0.17
Minimum	-0.46
Maximum	0.65

Correlation measures how closely two assets move together. Values near +1 indicate strong co-movement, near 0 indicates independence, and negative values indicate inverse movement.

Bitcoin and Gold: Risk Analysis

Bitcoin experienced its maximum drawdown of -66.7% from 2022-03-29 to 2022-11-21. It has not yet recovered to its previous peak.

Gold experienced its maximum drawdown of -20.8% from 2022-03-08 to 2022-09-26. It has not yet recovered to its previous peak.

Smaller drawdowns and faster recoveries indicate lower downside risk and greater resilience during market stress.

Sharpe Ratio of BTC and XAU

BTC Sharpe Ratio

↓ -1.38

XAU Sharpe Ratio

↓ -0.15

Sharpe ratio measures return per unit of risk (volatility). A higher Sharpe indicates better risk-adjusted performance. Both Sharpe ratios were negative (XAU -0.15 vs BTC -1.38), meaning both underperformed the risk-free rate; XAU was less negative.

A Sharpe above 1.0 is generally considered good, above 2.0 is excellent. Negative Sharpe means the asset underperformed the risk-free rate. Calculated on each asset's full 365-day lookback of available prices and annualized using the asset calendar (365 for crypto, 252 trading days for equities/ETFs/metals).

Sortino Ratio of BTC and XAU

BTC Sortino Ratio

↓ -1.81

XAU Sortino Ratio

↓ -0.21

Sortino ratio measures return per unit of downside risk. Unlike Sharpe, it only counts downside deviation (returns below the target return). XAU had better downside-adjusted returns.

A higher Sortino is better. It's useful when upside volatility is common (crypto is the obvious example). Downside deviation: BTC 48.6% vs XAU 10.5%. Calculated on each asset's full 365-day lookback of available prices, using the daily risk-free rate as the target return, and annualized using the asset calendar (365 for crypto, 252 trading days for equities/ETFs/metals).

Tail Risk & Distribution Shape (2022): Bitcoin vs. Gold

This section looks at the shape of daily returns, not just the average. Tail stats are computed per asset on its own daily series (crypto includes weekends). We use daily log returns $\ln\left(\frac{P_t}{P_{t-1}}\right)$ so multi-day moves add cleanly.

Definitions: Value at Risk (VaR), Expected Shortfall, skew, kurtosis, and fat tails.

Metric (2022)	BTC	XAU
5% VaR (daily log return)	-5.80%	-1.61%
5% Expected Shortfall (CVaR)	-9.10% (worst 19 days)	-1.98% (worst 13 days)
Skew	-0.59	0.04
Excess kurtosis	4.67	0.78

Downside co-moves (2σ) — 2022

Computed on shared dates only (n=257). A “2σ downside move” means a shared-close log return more than 2 standard deviations below that asset’s own mean on this shared-date series. Dates below show simple returns (%) for readability.

Read this as “how ugly the ugly days get”, not as a precise forecast. One-year samples are small, so tail estimates are inherently noisy.

Inputs & conventions

Shared window for pair metrics: 2022-01-01 → 2022-12-31 (last shared close).
Rolling correlation sample (shared closes): N/A
Annualization (days/year): BTC: 365 days/year; XAU: 252 days/year.
Risk-free rate: Uses the 3-month U.S. Treasury yield (FRED: DGS3MO), averaged over each asset’s window:

BTC: 4.50%.

XAU: 4.50%.
Volatility drag (rule of thumb): Estimated from annualized volatility (simple returns). For the log-return framing, see Log returns.

BTC: ≈ -20.4%/yr

XAU: ≈ -1.1%/yr
Data alignment: No forward fill. Correlation and tail co-moves are computed on shared closes only.
For cross-calendar pairs (e.g., crypto vs stocks), weekend/holiday moves roll into the next shared close.
Return conventions: Volatility/Sharpe/Sortino use simple daily returns. Tail-risk uses daily log returns for distribution stats (but tables show simple returns). Log returns.

Formulas

Daily simple return

r_t = \frac{P_t}{P_{t-1}} - 1

Volatility

\sigma_{ann} = \sigma(r_t)\sqrt{A}

Volatility drag (approx.)

\text{drag} \approx \tfrac{1}{2}\sigma_{ann}^2

Sharpe Ratio

S = \frac{A\,\bar{r} - r_f}{\sigma(r_t)\sqrt{A}}

Sortino Ratio

So = \frac{A\,\bar{r} - r_f}{\sqrt{\mathbb{E}[\min(0,\,r_t - r_f/A)^2]}\,\sqrt{A}}

Maximum Drawdown

MDD = \min_t\left(\frac{P_t}{\max_{s \le t} P_s} - 1\right)

Average Correlation

\rho = \frac{\operatorname{cov}(r^A,\,r^B)}{\sigma_A\,\sigma_B}

Log returns

\ell_t = \ln\left(\frac{P_t}{P_{t-1}}\right)
