January 2016, retail FX EUR/USD spreads operated typically in 0.5-1.5 pip range across substantial broker base. May 2026 reality shows EUR/USD raw spreads operating substantially in 0.0-0.3 pip range across ECN broker categories with separate commission structure. The 10-year spread compression represents substantial retail FX cost structure evolution driven by sustained liquidity provider framework expansion (XTX Markets, Citadel Securities), execution algorithm refinement, and continued broker competitive dynamics. We pulled the 2016-2026 spread compression decade reconstruction, the liquidity provider framework dynamics, and what the trajectory reveals about retail FX cost structure trajectory.

2016 baseline spread reality

The 2016 retail FX baseline:

EUR/USD spread reality. Major-pair EUR/USD spreads operating typically 0.5-1.5 pip range across substantial broker base.

GBP/USD spread reality. Major-pair GBP/USD spreads operating typically 0.8-2.0 pip range.

USD/JPY spread reality. Major-pair USD/JPY spreads operating typically 0.5-1.5 pip range.

Cross-pair spread reality. Cross-pair spreads operating typically 1.5-4.0 pip range reflecting reduced cross-pair liquidity.

Exotic pair spread reality. Exotic pair spreads operating substantially wider range reflecting reduced exotic-pair liquidity.

Account type framework. Broker account type framework supporting various spread-commission combination structures.
