Forex spreads at major retail brokers have continued compressing through the 2024-2026 period as the structural shift in interbank market making — non-bank liquidity providers (NBLPs) including XTX Markets, Citadel Securities, Jane Street, Two Sigma, and others — has progressed. NBLPs now provide a substantial share of major-pair liquidity in interbank markets, displacing some of the historical tier-1 bank dominance. The competitive pressure has compressed spreads at the LP level, with corresponding compression at retail brokers as their LP costs have decreased. The trend has been progressive rather than sudden, but cumulative through multiple years.
For retail traders, the cumulative effect is meaningful. EUR/USD spreads at top ECN brokers in 2018 averaged 0.3-0.5 pips on raw spread accounts; in 2026, equivalent spreads average 0.0-0.2 pips. The 0.2-0.3 pip compression compounds across millions of retail trades.
The NBLP Rise
Non-bank liquidity providers have grown to substantial market share in interbank FX through structural changes since 2010.
XTX Markets. Now one of the largest single liquidity providers in interbank FX. Specific market share substantial in major pairs.
Citadel Securities. Substantial FX market making in addition to its broader securities business.
Jane Street, Two Sigma, and other quantitative trading firms. Substantial FX presence as part of their broader trading activity.
Specific other NBLPs. Various smaller NBLPs contributing to the broader competitive landscape.
The NBLPs have specific advantages over traditional banks: lower cost structures, faster technology, narrower regulatory constraints in some respects, and ability to operate at very high frequencies that produce competitive pricing.
Why NBLPs Have Disrupted Tier-1 Banks
Several structural factors enabled NBLPs to compete effectively.
Post-2008 bank balance sheet constraints. Tier-1 banks' FX market making contracted as Basel III and other regulations constrained risk-taking. NBLPs filled the gap.
Technology advantages. NBLPs operate sophisticated technology stacks designed for high-frequency market making. Specific latency advantages over bank systems.
Narrower regulatory perimeter. NBLPs face different regulatory constraints than banks. Specific advantages in operational flexibility.
Specific cost structure. NBLPs operate with lower cost structures than banks for FX market making activities specifically.
Specific algorithmic sophistication. NBLPs deploy increasingly sophisticated algorithms for market making and risk management.
The combined factors produced effective competition that compressed bank market making margins and required corresponding tightening across the broader market.
How the Compression Has Played Out at Retail
For retail forex brokers, the LP-level compression has translated into retail spread compression.
Major-pair compression. EUR/USD, GBP/USD, USD/JPY have all seen material compression. Spreads at top ECN brokers approximately halved across 2018-2026.
Specific instrument variation. Different instruments have seen different compression magnitudes. Major pairs most. Minor pairs less. Exotic pairs not at all in some cases.
Specific broker variation. Different brokers have passed through LP compression differently. Top-tier ECN brokers passed through aggressively. Some other brokers retained margins.
Session-specific patterns. Compression most visible during peak liquidity windows (London-NY overlap). Less visible during off-hours.
Specific Numbers from 2018 to 2026
| Year | Top-tier ECN EUR/USD spread (avg) | Comment |
|---|---|---|
| 2018 | 0.3-0.5 pips | Pre-substantial NBLP penetration |
| 2020 | 0.2-0.4 pips | NBLPs growing share |
| 2022 | 0.1-0.3 pips | NBLPs substantial share |
| 2024 | 0.1-0.2 pips | NBLPs dominant share |
| 2026 | 0.0-0.2 pips | Mature competitive landscape |
The progression is observable. Specific brokers' specific data shows similar patterns.
What Continued Compression Could Look Like
Whether spreads compress further depends on several factors.
LP-level competition. Continued NBLP-bank competition could produce further compression. Diminishing returns as spreads approach physical execution costs.
Specific cost structures. Brokers' operational costs (technology, regulation, marketing) have a floor. Spread compression below the floor unsustainable.
Specific commission compression. Some brokers have lowered commissions to compete on all-in cost rather than spread alone. Continued competition possible.
Specific platform competition. New platform offerings (algorithmic trading platforms, specific innovative offerings) could drive cost competition.
The marginal additional compression possible is smaller than the historical compression delivered.
What This Means for Retail Trader Strategy
For retail traders in 2026, the compressed spread environment has several implications.
Lower transaction cost. Cumulative trading costs have decreased materially over the years. Active traders benefit substantially.
Specific broker selection focus. Within the compressed environment, broker selection focus on commission, execution quality, regulatory framework rather than just raw spread.
Specific niche broker advantage. Smaller specialty brokers with specific advantages can compete on dimensions other than raw spread.
Specific event-day attention. Calm-market spreads compressed; event-day spreads still substantial. Event-day execution quality matters more relative to calm-market spread.
Specific multi-broker allocation. With multiple brokers offering compressed spreads, multi-broker portfolios can optimize across broker-specific characteristics.
The Decision Reading
For retail traders in 2026, the compressed spread environment is a substantial benefit relative to historical conditions. Specific broker selection should weight execution quality and other characteristics more heavily than raw spread differentiation, since the differentiation has compressed.
For longer-horizon analysis, continued compression is possible but with diminishing returns. The specific structural environment of 2026 likely persists with modest evolution rather than dramatic shifts.
