Retail Exchanges See Concentration as Custody Grows
Decentralized exchanges (DEXs) show rising trading concentration, while institutional custody for crypto-assets and digital assets expands among major banks and custodians.[1][5]
Overview
- DEX trading volume concentrated in 20% of liquidity pools across examined platforms, accounting for over 90% of activity per DEX, based on on-chain data from largest DEXs.[1]
- Liquidity provision in top DEX pools dominated by small number of providers holding significant liquidity pool tokens, indicating supply concentration.[1]
- Global banks’ prudential exposures and custody of crypto-assets increased notably from low base, with announcements of stablecoin products and partnerships.[5]
- DEX activity rose post-FTX collapse and after Silicon Valley Bank crisis, reaching nearly 20% of total DeFi trading by H2 2022.[1]
- Custodians positioned for tokenization via trusted infrastructure for safekeeping, corporate actions, and settlement in programmable token environments.[3]
- Stablecoin issuers’ reserve holdings grew comparable to foreign governments or large money market funds, concentrated among few issuers.[5]

DEX Trading Intensity and Concentration Patterns
Recent on-chain analysis reveals heightened concentration in DeFi liquidity on decentralized exchanges. In sampled DEXs, just 20% of pools captured more than 90% of trading volume.[1] Trade counts remained low in these dominant pools, pointing to focused activity rather than broad participation.
This pattern held across automated market makers (AMMs). Liquidity providers numbered few in high-volume pools, with their token holdings representing bulk of supply.[1] Post-FTX, DEX volumes spiked, then grew further amid SVB stress, hitting almost 20% of DeFi total by late 2022.[1]
Custom Metric: DEX Pool Concentration Ratio
| DEX Category | Top 20% Pools’ Volume Share | Avg. LP Count in Top Pools | Data Period |
|---|---|---|---|
| Sampled DEXs | >90% | Low (small number) | Up to H2 2022 [1] |
| Overall DeFi | ~20% total trading | Concentrated providers | H2 2022 [1] |
Data derived directly from on-chain dataset of largest DEXs; no recent 2025-2026 updates in sources.[1]
Retail-like activity on DEXs contrasts with traditional retail exchanges, though sources lack direct CEX retail flow metrics. Concentration risks amplify if volumes stay pool-specific.
Institutional Custody Expansion in Crypto and Digital Assets
Major financial institutions ramped up crypto custody. Prudential exposures and assets under custody rose significantly, starting from low levels.[5] Banks announced stablecoin integrations for payments, proprietary issuance, and investment services.[5]
Custodians lead in tokenization readiness. They handle asset safekeeping and settlement finality, essential for distributed ledger tokens.[3] Heightened institutional demand for digital assets drives this, aided by regulatory tailwinds and balance sheet gains.[3]
Global custody assets historically concentrated: top players like BNY Mellon (12,170 bn, 2006 data), State Street (11,900 bn), Citigroup (9,142 bn).[8] Mergers noted, e.g., BNY-Mellon, State Street-Investor Financial.[8] Recent reports affirm custodians’ edge in post-trade for tokenized assets.[3]
Stablecoin reserves by few issuers match large money market funds or government holdings, focused on short-end yields.[5] This boosts interlinkages with traditional finance.[5]
Custom Metric: Custody and Exposure Growth Snapshot
| Metric | Change Description | Key Players Affected | Source Period |
|---|---|---|---|
| Prudential Exposures | Significant increase from low base | Global banks | Recent [5] |
| Assets Under Custody | Notable rise | Major institutions | Recent [5] |
| Stablecoin Reserves | Comparable to MMFs/governments | Few issuers | Recent [5] |
| Tokenization Readiness | High via infrastructure | Custodians | 2025 outlook [3] |
Table aggregates direct statements; lacks precise volumes or 2026 figures.[3][5]
On-chain custody trends absent in sources, but OECD dataset hints at DEX-CEDEX interplay without specifics.[1]
On-Chain Insights into Flows and Holder Behavior
OECD’s original on-chain dataset covers top DEXs, showing mints of liquidity tokens clustered among few providers.[1] This mirrors trading concentration. No Glassnode, Arkham, Nansen, or Santiment data in results; analysis limited to provided on-chain evidence.[1]
Original Angle 1: Post-Crisis DEX Resilience
DEX volumes climbed after FTX failure-investor confidence dip spurred shift from CEXs.[1] SVB aftermath added lift. Yet low trade counts in concentrated pools suggest not mass retail surge, but targeted activity.[1]
Original Angle 2: Custody vs. DEX Supply Divergence
While DEX liquidity concentrates (few LPs dominate), institutional custody disperses risk via bank balance sheets.[5][3] Stablecoin reserves centralize short-term holdings.[5] No direct flow linkage data; interlinkages noted qualitatively.[5]
Original Angle 3: Historical Custody Benchmarks
2006 custody rankings provide baseline: top 3 held ~33,000 bn in assets.[8] Fast-forward, crypto custody grows from “low base,” per FSB.[5] Gap highlights shift, but no chained metrics available.
Long-term (12-36 months): Custodians eye real-time post-trade, with digital assets as key driver.[3] Projections baseline on regulatory support; upside if tokenization scales, per Citi GPS.[3] No quantitative forecasts.
Comparison Table: Concentration Metrics Across Venues
| Venue Type | Concentration Indicator | Scale/Details | Timeframe |
|---|---|---|---|
| DEX Pools | 20% pools >90% volume | Low trade count, few LPs | Up to 2022 [1] |
| Liquidity Supply | Few providers hold bulk tokens | Pool-level dominance | Up to 2022 [1] |
| Institutional Custody | Crypto exposures up from low base | Banks, stablecoin reserves | Recent [5] |
| Global Custody | Top firms ~top ranks (2006: 33k bn) | Mergers consolidating | 2006+ [8] |
Unique aggregation; underscores retail exchanges post higher trading intensity while institutional custody concentrates without causal inference.[1][5]
Traditional Exchange and Banking Liquidity Context
FSOC 2025 report notes Treasury market liquidity strains from eSLR constraints on bank broker-dealers.[2] Bid-ask spreads widened, depth fell.[2] Auctions show strong end-user bid-to-cover, lower primary dealer awards.[2]
OCC Spring 2025: Banking liquidity stable, LTD ratios below pre-pandemic for system, nearing for small banks.[4] Retail credit steady amid wage growth outpacing inflation since 2019, but sentiment sours.[4]
No direct retail exchange trading intensity data ties to crypto; CRE stabilizing, RRE resilient with affordability issues.[2][4]
Risks and Uncertainties
Downside scenario: DEX concentration exacerbates liquidity risks if dominant pools face stress, as few LPs could withdraw.[1] Uncertainty in inflation, EFFR paths demands robust IRR testing.[4]
Sources conflict on timelines-OECD caps at H2 2022, FSOC/OCC at 2025.[1][2][4] No 2026 data; on-chain lacks trackers like Glassnode. Projections distinguish baseline (monitoring interlinkages) from upside (tokenization via custodians).[3][5]
Missing: Precise retail exchange volumes, recent on-chain custody flows, quantitative holder metrics. Analysis sticks to verified statements.[1][5]
Retail Exchanges Post Higher Trading Intensity While Institutional Custody Concentrates appears in DEX volumes post-crises, custody in bank growth-yet data stops short of real-time confirmation.[1][5]
Stablecoin issuer concentration at short-end yields poses systemic concern if yields shift.[5]
Over 12-36 months, custody expansion supports tokenized asset integration, per institutional reports, assuming regulatory continuity.[3]
Bank liquidity metrics remain stable amid deposit competition.[4]
FSOC flags ongoing CRE/RRE monitoring.[2]
DEX pool dominance persists in available data.[1]
Custodians’ infrastructure positions them centrally.[3]
