September 22, 1985, G5 finance ministers announced coordinated USD-depreciation intervention at Plaza Hotel, New York. The 1985 FX market context operated through substantially voice broker dominated framework with substantial pre-electronic commission framework operation. Voice broker commissions plus bank-bank execution framework defined retail-equivalent FX cost structure substantially exceeding modern retail FX cost reality. Modern retail FX market emerged across post-1995 period with substantially different cost structure framework. We pulled the Plaza-era commission framework reconstruction, the multi-decade commission trajectory dynamics, and what 40 years post-Plaza reveal about FX cost structure transformation.
