Cryptocurrency Markets
Total cryptocurrency market capitalisation sits near $2.7 trillion in 2026, dominated by Bitcoin ($1.4T) and Ethereum ($430B). US spot Bitcoin ETFs hold over $90B in assets two years after launch. Stablecoin supply has topped $200B with Tether and Circle accounting for the bulk.
Key insights
ETFs reshape who holds Bitcoin
The January 2024 SEC approval of eleven spot Bitcoin ETFs (BlackRock, Fidelity, Ark, Bitwise and others) routed institutional flows into BTC for the first time at scale. Net inflows reached $58B in the first 18 months. Ethereum ETFs followed in mid-2024 and now hold roughly $14B. ETF holders have become the marginal price-setter, displacing the boom-bust dynamics of earlier cycles.
Adoption highest where it solves local problems
The Chainalysis Global Crypto Adoption Index ranks India, Nigeria, Vietnam, USA and Ukraine at the top. Common drivers: high domestic inflation, weak banking access, large remittance corridors, capital controls. Stablecoins (mostly USDT) dominate emerging-market on-chain volume — they function as USD bank accounts where USD bank accounts are unavailable.
Regulation is converging on disclosure
The EU's MiCA framework came fully into force end-2024, imposing reserve, redemption and disclosure rules on stablecoin issuers and licensing on exchanges. The US passed the GENIUS stablecoin act in 2025. The UK, Hong Kong, Singapore and the UAE have all rolled out comparable regimes. The trend is towards regulated, on-exchange crypto with offshore unregulated venues squeezed.
Crypto market cap by asset (2026)
USD billions
Key Finding: Bitcoin alone accounts for 52% of total crypto market cap; stablecoins (USDT + USDC) make up 8%.
Stablecoin supply 2019–2026
Total outstanding, USD billions
Key Finding: Stablecoin supply rose from <$5B (2019) to $215B (2026). USDT has held 65–70% market share throughout.
Methodology & caveats
Market cap is not 'money in'
Crypto market cap = circulating supply × spot price. It overstates the amount of capital actually invested — a small marginal trade can move price and apparent cap by a multiple. 'Realized cap' (the value of each coin at the price it last moved) is a better proxy for capital base.
Stablecoin reserve composition
Reputable stablecoin issuers (Circle/USDC, Tether/USDT post-2023) publish monthly attestations showing reserves in T-bills, repo and cash. USDC reserves sit ~85% in short-dated T-bills and repo. USDT discloses similar breakdowns. Older 'algorithmic' stablecoins (Terra/UST) collapsed in 2022 and are largely defunct.
Adoption metrics
Chainalysis ranks countries on on-chain volume (weighted by purchasing power and population), retail vs institutional split, and DeFi/centralised exchange usage. The index captures activity, not necessarily holdings. Holding data is unobservable at the individual level — exchanges and wallets are the only proxies.
