Understanding the structural differences between OTC and exchange-traded derivatives is fundamental to FRM Part I. The key distinction lies in how counterparty risk is managed, and post-2008 regulatory reforms have significantly changed the OTC landscape.

**Exchange-Traded Derivatives**
These are standardized contracts (futures, listed options) traded on organized exchanges like CME or Eurex. Every trade is novated to a central counterparty (CCP) that stands between buyer and seller. The CCP eliminates bilateral counterparty risk through daily margining.

**OTC Derivatives (Traditional Bilateral)**
Historically, OTC derivatives (interest rate swaps, credit default swaps, exotic options) were purely bilateral contracts between two counterparties — typically large banks. Each party bore the other's credit risk directly. If Greystone Bank had a $500 million interest rate swap with Pinnacle Securities and Pinnacle defaulted, Greystone could face a massive replacement cost.

**OTC Derivatives (Post-Reform: Centrally Cleared)**
Dodd-Frank and EMIR now mandate that standardized OTC derivatives be cleared through CCPs. This transforms the bilateral risk into a centralized model similar to exchange-traded products, though the contracts themselves remain customizable.

**Key Differences Summarized:**

| Feature | Exchange-Traded | OTC Bilateral | OTC Cleared |
|---|---|---|---|
| Standardization | Fully standardized | Fully customizable | Standardized terms |
| Counterparty risk | To CCP (mutualized) | To counterparty (bilateral) | To CCP (mutualized) |
| Margining | Daily variation + initial | Per CSA (often threshold-based) | Daily variation + initial |
| Transparency | Full price transparency | Opaque (bilateral quotes) | Trade repository reporting |
| Liquidity | High (order book) | Negotiated (dealer network) | Moderate |
| Capital charge | Lowest (2% RW for CCP) | Highest (CVA + default risk) | Low (CCP qualifying) |

**Worked Example — Counterparty Risk Impact:**
Harborview Capital enters a 5-year interest rate swap with notional value of $200 million.

- If cleared through a qualifying CCP, Basel III assigns a 2% risk weight to the trade exposure, requiring minimal capital.
- If bilateral with Pinnacle Securities (rated A), the risk weight might be 50%, requiring 25x more capital for the same notional.

This capital differential is why regulators pushed so hard for central clearing after 2008 — it reduces systemic interconnectedness.

**Exam Tip:** Questions often test whether you understand that central clearing does not eliminate counterparty risk — it concentrates and mutualizes it through the CCP's default waterfall (member default fund contributions, CCP equity, etc.).
