The macro signal shown by the copper-to-gold ratio after the Bitcoin halving

Looking at the history of Bitcoin, a pattern emerges where market conditions significantly change after each four-year Bitcoin halving cycle. In particular, the copper-to-gold price ratio is one of the first macroeconomic indicators to reflect shifts in risk appetite, showing a strong correlation with Bitcoin halving cycles. After the fourth Bitcoin halving in April 2024, these signals are beginning to manifest.

Historical Alignment of Halving Cycles and Macro Signals

Bitcoin halving is an event where the rewards for miners are cut in half, reducing the supply of cryptocurrency—a key mechanism for tightening supply. Historically, these cycles have acted as catalysts for long-term bull markets.

The copper-to-gold ratio exhibits an interesting pattern of movement alongside Bitcoin halvings. Copper responds sensitively to industrial demand and economic expansion, while gold is preferred as a safe-haven asset during times of high uncertainty. Therefore, an increasing copper-to-gold ratio signals rising risk appetite among investors.

Major peaks in the copper-gold ratio observed in 2013, 2017, and 2021 all coincided with cycle highs in Bitcoin prices. These periods reflected strong global growth expectations and heightened speculative risk-taking across assets.

Changes in the Macro Environment Post-2024 Bitcoin Halving

At the time of the April 2024 Bitcoin halving, the copper-to-gold ratio was still in a bearish trend. However, the situation changed rapidly afterward. After hitting a low of about 0.00116 in October, the ratio has since risen to around 0.00136. This marks an important shift away from years of decline.

Simultaneously, notable changes appeared in commodity markets. Copper prices surged past a record $6 per pound, and gold traded near $4,455 per ounce, approaching record levels. Over the past few months, copper has risen by 18%, and gold by 14%, with copper’s outperformance reflecting not just supply constraints but improving growth expectations.

These movements suggest a fundamental shift in market sentiment following the halving. As mining rewards decrease and supply tightens, investor risk appetite appears to be recovering significantly.

Outlook for 2026 and the Significance of These Signals

When the copper-gold ratio reverses in tandem with Bitcoin halving cycles, it has often foreshadowed important rallies. Currently, Bitcoin trades around $70,900, with macro signals pointing toward a positive outlook.

If copper remains strong, it could indicate a risk-on environment extending into 2026. These risk appetite signals, coupled with reduced supply post-halving, could positively influence the entire cryptocurrency market.

Interestingly, this trend aligns with the growth of the prediction market ecosystem. Recently, new venture capital firms like 5c Capital have been established to support prediction market platforms such as Polymarket and Kalshi, reflecting increased risk tolerance among investors. This fund aims to raise up to $35 million to support about 20 early-stage startups over the next two years, focusing not just on exchanges but also on infrastructure like data tools, liquidity provision, and compliance systems.

Given the clear macro signals and the alignment with the copper-gold ratio’s upward trend during halving cycles, the current period warrants close attention. If historical patterns and current indicators continue to align, the cryptocurrency market could be entering a new medium-term bullish phase.
