Settlement: crypto's instant vs forex's T+2

When does a trade actually finish?

Settlement is the moment a trade is truly done — when ownership has transferred and there's no take-backs. The trade execution (when you click buy) and the settlement (when you actually own the thing) aren't always at the same instant. In different markets, the gap between those two events ranges from seconds to days. That gap matters for how you think about your capital.

Crypto is the fastest. On a centralized exchange, a spot trade settles essentially instantly — the moment your order matches, the exchange updates its internal ledger and the new balance is yours to trade with again. On a DEX, settlement is whenever the blockchain confirms the transaction — usually seconds on chains like Solana, a minute or two on Ethereum L2s, longer on Bitcoin's own chain. Either way, when settlement is done, the asset is irrevocably yours and you can use it immediately.

Forex follows a much older convention. The wholesale forex market settles T+2, meaning trade plus two business days. If you sell EUR/USD on Monday, the actual cash deliveries between banks happen Wednesday. This is a relic of the interbank banking system — it takes that long for the actual money movements to clear between correspondent banks around the world. Equities are similar: US stocks settle T+1 (one business day) after the 2024 industry move from T+2 to T+1.

Why does this matter to you? Three reasons. One: capital efficiency. In crypto you can close a position and immediately redeploy that capital. No waiting. Two: counterparty risk. When you close a forex trade through a broker, you're trusting that broker to honor the position until settlement. In crypto on a CEX you're trusting the exchange, but the timeline is much shorter. Three: withdrawal timing. When you want to pull dollars out of a forex broker, expect days. When you want to pull crypto off a CEX, expect minutes to hours plus network confirmation time.

Recap: crypto settles in seconds to minutes. Equities settle T+1. Forex settles T+2 wholesale, hidden by retail brokers via rollovers. You can move capital faster in crypto, but the underlying convention difference is mostly invisible to retail until withdrawal time.
