The Vibe: The old-school financial system — banks, brokers, stock markets, and central banks — before crypto and DeFi came along.
The Details: TradFi refers to conventional finance: banks (JPMorgan, Goldman Sachs), stock exchanges (NYSE, Nasdaq), brokers (Fidelity, Interactive Brokers), payment systems (Visa, SWIFT), and regulators (FED, SEC). It relies on centralized institutions, intermediaries, KYC/AML rules, and slow/expensive cross-border transfers. In 2026, TradFi is increasingly interacting with crypto: banks offer custody, spot ETFs bring BTC/ETH to brokerage accounts, and institutions allocate to digital assets. The term is often used to contrast with DeFi (decentralized, permissionless, on-chain finance).
Pro Tip: TradFi offers regulated safety and easy access (via ETFs, brokers) but less privacy and control. Use TradFi for fiat on-ramps or institutional exposure; use DeFi for self-custody and higher yields. Watch TradFi adoption (more banks/ETFs) as a bullish signal for crypto.
