Bitcoin-Gold Correlation Nears Six-Year High, Is BTC Really a Safe Haven?

• Bitcoin’s 90-day correlation with gold has climbed to its highest level in nearly six years, though the reading of around 0.50 remains moderate
• A 22.4% weekly gain followed Treasury buybacks, rising US debt and renewed concerns about dollar weakness
• Higher volatility and limited central-bank adoption still prevent BTC from matching gold’s safe-haven status

The Bitcoin-gold comparison is back in focus after both assets surged during a difficult week for US bonds. Their 90-day relationship is now the strongest it has been since 2020, reviving the idea of BTC as digital gold. Some investors see this as proof that Bitcoin has become a defensive asset. Yet the correlation behind that claim is less striking than the headline suggests, and other data shows how much still separates Bitcoin from gold.

Why Bitcoin and Gold Suddenly Moved Together

The bond market helped drive the latest Bitcoin and gold rally. On August 19, the US Treasury announced that it would double buybacks of longer-dated securities to at least $4 billion per operation. In addition, a separate $12.5 billion buyback of short-term debt was recently carried out. While designed to improve market liquidity, the operations also increased concerns about US debt and policy intervention.

Both scarce assets reacted quickly. Bitcoin gained 22.4% during its strongest week since March 2024, according to a report from Bitwise. Bitcoin later climbed above $80,000, reaching a three-month high. It had gained around 28% in August by that point. At press time, Bitcoin’s price was at $81,041.53 following a 4.8% rise. Gold and several other markets also registered notable gains over the past day.

Tim Sun, senior researcher at HashKey Group, said,

“That would create a ‌relatively ⁠supportive macro backdrop for assets such as Bitcoin and gold.”

Standard Chartered’s Geoff Kendrick was more direct, calling the Treasury action “exactly the type of thing Bitcoin loves.” Both comments point to the same trade that investors were moving away from the dollar and toward assets with limited supply.

The Six-Year High Is Only Half the Story

Bitwise’s data placed the 90-day Bitcoin-gold correlation at about 0.50 by the end of August. The last similar reading came in 2020, following the large fiscal and monetary response to the pandemic.

A correlation of 1 would mean Bitcoin and gold move in the same direction at the same rate. A reading of zero suggests there is no consistent relationship. The current figure sits somewhere in the middle.

There is another detail worth noticing. Bitwise states that a correlation between -0.5 and 0.5 is traditionally described as “low” or having no meaningful relationship. Bitcoin has only just reached the edge of that range.

Calling it a six-year high is accurate. Treating it as proof that Bitcoin now behaves as gold goes further than the data allows.

It should be noted that a 90-day correlation gives more weight to recent events and changes than older trading sessions in the calculation. Bitcoin and gold may be moving together because both are responding to the same concerns about debt and the dollar. This does not guarantee they will react similarly during the next recession, banking shock, or rush for cash.

GLD and IBIT Attracted Heavy Trading

ETF activity added more weight to the digital gold narrative. On September 3, Bloomberg ETF analyst Eric Balchunas reported that SPDR Gold Shares, or GLD, ranked fourth among US ETFs by trading volume. BlackRock’s iShares Bitcoin Trust, or IBIT, ranked sixth.

GLD recorded around $4.53 billion in volume, while IBIT reached about $3.48 billion. Balchunas called them “store of value frenemies” and said their combined ranking was probably “as high as they’ve ever been as a pair.”

This shows strong attention, though it does not prove investors were buying. Trading volume includes purchases and sales. Net ETF flows are needed to measure how much new money entered each fund.

Gold’s Reserve Lead Needs Some Context

Gold has institutional support that Bitcoin has not yet achieved. The European Central Bank (ECB) reported that gold represented 27% of global official reserves at the end of 2025, ahead of US Treasuries at 22%.

This crossover has been presented online as evidence of a large move away from Treasury debt. The ECB said it “largely reflects valuation effects.” Gold prices rose around 60% in 2025 after increasing 30% in 2024, automatically raising the market value of existing reserves.

Using gold’s price at the end of 2023 changes the comparison. Its share falls to 16%, while Treasuries rise to 26%. Actual demand remains strong. The World Gold Council’s 2026 survey found that 89% of participating central banks expected global gold holdings to increase over the following year. A record 45% planned to raise their own reserves, and 74% expected the dollar’s reserve share to decline over five years.

Respondents cited gold’s “performance during times of crisis, portfolio diversification and inflation hedging” among the main reasons for holding it. Bitcoin has yet to win similar acceptance from central banks.

Can Investors Treat Bitcoin as a Safe Haven?

The current data supports the view that Bitcoin is becoming a stronger hedge against currency debasement. Its negative relationship with the Dollar Index and weaker correlation with the Nasdaq suggest its role is changing.

The Bitcoin safe haven case remains less certain. A defensive asset should preserve value during severe market stress, while Bitcoin has often fallen sharply during sudden demand for cash. Its volatility also remains far higher than gold’s.

Investors should now watch whether the Bitcoin-gold correlation survives beyond the current 90-day window. Net ETF flows, real yields, dollar movements, and BTC’s performance during the next stock-market decline will offer a better test than one rally.

Bitcoin and gold are being bought for similar reasons. They still carry very different risks. Bitcoin may act like digital gold when debasement fears rise, but its larger gains come with much deeper potential losses.
