The evolving relationship between Bitcoin and gold: A regime shift analysis

This study explores the relationship between Bitcoin and gold, finding that they operated almost independently before 2017, but after a defined series of events, they began to exhibit mutual response dynamics.

Bitcoin and gold have become popular assets for investors seeking to preserve value against inflation and economic uncertainty. While they share certain characteristics, such as relative scarcity and a hedge against monetary debasement, the nature of their connection has been a subject of ongoing study.

Early analyses, covering the period from 2010 to October 2017, indicate that the two assets operated almost independently. A slight negative effect of gold prices on Bitcoin is observed, which can be estimated using threshold regression models. These models yield a negative coefficient (β ≈ -0.51) for gold on BTC with minimal predictive power, aligning with the view that BTC was mainly a speculative asset.

However, a significant shift occurs around October 2017, which is identified by parameter-stability tests and the CUSUM test. This change in regime is evident in the drastic shift in the correlation coefficient and Granger causality. After October 2017, the relationship becomes significantly positive (β ≈ +0.27), indicating that simultaneous interest in gold and Bitcoin as alternative assets increased.

This finding is congruent with the broader narrative of a shift in Bitcoin's perception, which began to attract investor flows due to its diversification potential and risk tolerance. The initial momentum of 2017 is also linked to the institutional crypto adoption boom.

Further analysis, extending the study through 2024, shows that after 2020, the intensity of interrelation increases moderately. This is visualized by the Impulse-Response Functions, which display sharper reactions of BTC to shocks in gold prices and vice versa, with more prolonged impacts.

Despite this interdependence, the overall correlation remains close to zero, and causality tests only provide weak evidence of gold→BTC influence, suggesting that their growing interdependence is being driven by global macroeconomic factors.

Both gold and Bitcoin respond to inflation, monetary policy shifts (e.g., interest-rate tightening or monetary expansion), and changes in global liquidity, which affect the demand for both assets. Additionally, geopolitical tensions and risk aversion tend to exert simultaneous pressure on both assets.

In an environment dominated by uncertainty and the search for alternatives outside the traditional banking system, the role of Bitcoin, a decentralized cryptocurrency, and gold, a traditional safe-haven asset, is becoming increasingly amplified.

For investors allocating part of their portfolio to safe-haven or diversification assets, understanding this relationship is crucial. Bitcoin still shows higher volatility compared to gold and, unlike the yellow metal, does not have a long history as a store of value. However, Bitcoin's joint response to market events offers partial hedging opportunities.

Maintaining balanced exposure to both assets, assessing the timing of structural breaks in their regimes, and adjusting allocations to integrate economic cycle phases can enhance risk management strategies in the current volatile market.

The relationship between Bitcoin and gold is evolving toward a more integrated profile while retaining elements of autonomy. The 2017 break marked the start of a positive link that became stronger after the pandemic. Going forward, its development will depend on global policy shifts and the maturity of the crypto market.

Grasping these technical nuances will enable investors and analysts to better anticipate the synergy between these two assets in their pursuit of security and diversification.
