Bitcoin's Halving Cycle May Be Replaced by 6-8 Year Debt Cycle
Bitcoin's (BTC) four-year cycle may be coming to an end, according to on-chain analyst Willy Woo. He argues that the market could adopt a 6-8 year debt cycle similar to traditional finance (TradFi). Historically, each halving cut the pace of new supply in half and reset Bitcoin's four-year cycle. However, Woo believes this mechanism has become too small to matter.
The last few cycles have seen a significant decline in supply growth, with issuance running near 0.8% of supply since April 2024, and the 2028 halving cutting it to roughly 0.4%. For comparison, gold miners added about 1.7% to above-ground stock in 2025, based on World Gold Council data.
Woo points out that Fidelity Digital Assets reached a similar conclusion in February, finding volatility declining even as Bitcoin set record highs, behavior it links to maturation. Spot exchange-traded funds (ETFs), which existed in no prior halving cycle, add to this structural break.
The 6-8 year debt cycle is a demand and liquidity event, in contrast to the halving's supply event. This framework was popularized by economist Ray Dalio, who describes it as a rhythm that stock and bond markets already trade on. The average post-war US cycle sits at around six years from peak to peak.
The debate is hard to settle, with Woo's version having a gap, Bitcoin has never faced a true business-cycle downturn since its launch in 2009. However, the test may be close, as there is a 60% chance of a 25 bps rate hike during the September FOMC meeting.
