Crypto and metals

Are crypto and metals telling the same story?

No. They have been moving in opposite directions. Over the last 90 days, ether against bitcoin and copper against gold scored -0.10 for moving together, on a scale from −1 to +1. They are not unusually far apart right now. Neither reacts clearly to US real interest rates, so there is no sign one force drives both.

1. Two ways to measure appetite for risk

Each number compares a risky asset with a safer one. When it rises, people are taking more risk.

Ether ÷ bitcoin0.0303One ether costs 0.0303 bitcoin. When this number rises, people are buying the riskier coin. When it falls, they are moving to bitcoin, the coin most people treat as the safer one.

Copper ÷ gold0.0016Copper is used to build things, so it does well when the economy grows. Gold is what people buy when they are worried. When this number rises, investors expect growth. When it falls, they are playing safe.

2. Do they move together?

No. At -0.10, they have tended to move in opposite directions over the last 90 days. The score runs from −1 (always opposite) to +1 (always together). Over three years it is +0.08.

Ether ÷ bitcoin (start = 100)Copper ÷ gold (start = 100)

Both lines start at 100. Look at whether they turn at the same times, not whether they overlap.

3. Are they unusually far apart?

We give each number a score for how unusual it is against its own past year, then take the difference. Past ±2 counts as far apart.

-1.82Not unusually far apart

No alarm. The gap is -1.82, inside the ±2 line. Over the last three years the gap was past that line on 30% of days, so crossing it is not rare. Being inside it only means the two are not unusually far apart. It does not mean they are moving together.

4. Is one force pushing both?

The real interest rate was 2.87% on 08 October 2026. It is what the US government pays, after inflation, to borrow for 10 years. When it rises, safe savings pay more, and risky assets often fall. This page tests whether both numbers react to it.

Ether ÷ bitcoin vs the rate · 3 years / 90 days-0.05 / -0.12Over three years, ETH/BTC falls slightly when real interest rates rise, but the link is weak (-0.05). Over the last 90 days: -0.12.

Copper ÷ gold vs the rate · 3 years / 90 days+0.04 / +0.03Over three years, copper/gold barely reacts to real interest rates (+0.04). Over the last 90 days: +0.03.

Result: Neither is clearly tied to real interest rates (ETH/BTC -0.05, copper/gold +0.04), so the shared-cause idea is not supported.

5. What would change the answer

Watch the 90-day score. If it climbs from -0.10 toward +0.3, the two have started moving together and the answer becomes yes. If both start to fall clearly when real interest rates rise, one force is pushing both. If the gap stays past ±2 for weeks, they are telling different stories.
