Key Findings (Jan 2026)
- 69 active FCMs in the U.S.
- Total adjusted net capital: $174.3B
- Total customer segregated funds: $367.6B
- Capital adequacy ratio: 3.6x (well above 1.0x minimum)

|---|---|---|

adj_net_capital / requirement | Overall capital buffer |
excess_capital_pct |
excess / adj_net_capital | Capital utilization |
swap_seg_share |
cleared_swap / (customer_seg + swap_seg) | OTC-to-exchange migration |

FCM customer seg / total customer seg | Per-broker market power |
Hypothesis Tests
| ID | Hypothesis | Method | Expected |
|---|---|---|---|
| H1 | Excess capital ratios decrease before market stress | Cross-correlation with VIX | Negative leading correlation |
| H2 | Cleared swap seg growth > futures seg growth | Paired t-test on MoM growth | Swap growth faster |
| H3 | Top-5 FCM concentration is increasing | Mann-Kendall trend test | Significant upward |
| H4 | Capital adequacy ratio is mean-reverting | ADF stationarity test | Reject unit root |
| H5 | FCM capital leads leveraged fund positioning | Granger causality (FCM → CFTC COT) | Significant at lag 1-2 |
Analysis Tasks
When analyzing FCM data:
- Load
data/processed/fcm_monthly_industry.csvfor trends - Load
data/processed/fcm_top_brokers.csvto identify dominant clearers - Track capital adequacy — ratio dropping below 2.0x would be systemic concern
- Monitor swap seg share growth as indicator of OTC derivative centralization
- Cross-reference with CFTC COT data: do positioning changes follow capital changes?
- Compare top FCM names with known prime brokers for hedge funds
Regulatory Context
- CFTC Rule 1.10: Monthly financial reporting required
- Customer protection: segregation requirements (Rule 1.20-1.30)
- Section 30.7: Foreign futures/options customer protection
- Post-MF Global reforms (2012): enhanced segregation, target residual interest
- FCMs must file within 17 business days of month-end
