Altcoin traders have been nursing a collective case of déjà vu — and frustration — as promises of a broad altcoin breakout keep falling flat this cycle. But crypto analyst Sykodelic argues the problem isn’t that altcoins are broken; it’s that the macro conditions that historically spark altcoin rallies never materialized.
Why altcoins lagged
Altcoins are the market’s liquidity-sensitive assets: they tend to surge when central-bank liquidity is plentiful, economic activity is expanding, and traders are willing to move risk further away from Bitcoin into smaller tokens. Sykodelic’s analysis shows that those exact macro drivers — Federal Reserve net liquidity and economic health measured by the Purchasing Managers’ Index (PMI) — have historically tracked the performance of the OTHERS index (total market capitalization of cryptocurrencies outside the top ten).
A tale of two cycles
- 2020–2021: Fed net liquidity rose rapidly, PMI was in expansion, and the OTHERS index climbed from under $100 billion to nearly $600 billion.
- This cycle: Fed net liquidity largely ranged for about two years with no clear trend, while PMI spent 26 consecutive months below 50 (contraction) until returning to expansion in January 2026. The OTHERS index reflected that environment — chopping sideways instead of mounting a sustained rally.
Signs that the backdrop is changing
Sykodelic’s chart suggests those headwinds may be easing. Key datapoints:
- Fed net liquidity appears to have bottomed and begun reversing upward.
- PMI readings have moved back into expansion: ISM Manufacturing PMI was 52.6% in January 2026 (up 4.7 percentage points from December’s 47.9%). It fell slightly to 52.4% in February 2026, but that still beat expectations of 51.8%.
What this could mean for altcoins
Taken together, a rising Fed net liquidity and a PMI back in expansion recreate the kind of macro environment that helped drive the last altcoin boom. On Sykodelic’s projection, that could be enough to push the OTHERS index back toward the roughly $560 billion range.
Bottom line
Altcoins didn’t fail this cycle so much as they were denied the macro fuel they typically need. With liquidity showing signs of recovery and PMI back above 50, the conditions for an altcoin season may finally be assembling — though the outlook still depends on whether those macro trends continue.
