Spot trading volume across 14 major centralized crypto exchanges totaled $429.0 billion in July, down 21.7% from $547.9 billion in June, according to data compiled by WuBlockchain. Every one of the 14 exchanges tracked recorded a month-over-month decline, pointing to a broad pullback in trading activity rather than weakness concentrated at any single platform.
Binance remained the dominant venue by a wide margin, processing $196.5 billion, or 45.8% of total volume. OKX followed with $41.6 billion and Bybit with $36.3 billion, leaving the top three exchanges responsible for 64.0% of all spot trading across the group.
DEXs Grab a Bigger Slice of a Shrinking Pie
The centralized exchange slowdown coincided with decentralized exchanges capturing a record share of overall spot activity. The DEX-to-CEX spot volume ratio closed July at roughly 24%, its highest level since The Block began tracking the metric, up from about 17% a year earlier. That milestone came with a catch: absolute DEX spot volume itself fell roughly 26% month-over-month to about $130.8 billion, its lowest level in nearly two years. DEXs aren't so much winning share as losing less than centralized platforms are.
A Second Straight Month of Contraction
July's decline follows a 5.1% drop in spot volume in June, extending a stretch of cooling activity across the exchange sector. Combined with thin summer liquidity and low volatility that traders have separately flagged in Bitcoin markets, the July numbers reinforce a picture of a market in a holding pattern rather than one seeing a rotation of volume toward any particular venue type.

What It Means for Exchange Competition
With Binance still commanding nearly half of tracked spot volume even as the overall market contracts, smaller centralized exchanges are absorbing a disproportionate share of the slowdown. That dynamic, paired with DEXs increasingly used for memecoins and newly issued tokens unavailable on larger platforms, suggests the competitive pressure on mid-tier centralized exchanges is intensifying even as headline volume shrinks across the board.
