The retail CD is familiar to most savers — a depositor commits funds for a fixed term (3, 6, 12, 24, or 60 months) at a fixed rate, earning more than a standard savings account in exchange for accepting an early withdrawal penalty (typically equal to several months' interest).\n\nThe wholesale or jumbo CD market operates differently. Large negotiable CDs with face values of $1 million or more are issued by commercial banks as a primary funding mechanism and trade freely in the secondary market (unlike retail CDs). These NCDs are priced as discount instruments: Proceeds = Face Value / [1 + (Rate × Days/360)]. The secondary market for NCDs allows institutional investors (money market funds, corporations, municipalities) to manage their short-term cash positions with daily liquidity while earning yields slightly above comparable-maturity Treasury bills.\n\nThe CD market is deeply intertwined with LIBOR history (now SOFR). The London Interbank Offered Rate was originally derived from rates at which banks could issue CDs to each other in the London interbank market. When LIBOR was manipulated by major banks (the scandal revealed in 2012), the scandal reflected the CD/interbank deposit market's susceptibility to benchmark manipulation. SOFR, derived from actual Treasury repo transactions, has replaced LIBOR as the primary risk-free rate benchmark.\n\nFrom a yield perspective, CDs occupy the risk-return spectrum between Treasury bills (lowest risk, lowest yield) and commercial paper (higher risk, higher yield). The CD-Treasury spread (CD minus T-bill yield of the same maturity) captures bank credit risk and liquidity premium, widening during periods of banking stress (as it did sharply in 2008, 2011, and 2023 during the Silicon Valley Bank failure). This spread is monitored as an indicator of bank funding conditions and systemic risk.\n\nFor institutional cash managers, the choice between CDs, T-bills, commercial paper, and money market funds involves careful analysis of yield, credit risk, and liquidity. Prime money market funds invest in CDs (among other instruments) and are subject to SEC Rule 2a-7 concentration limits (maximum 10% in any one issuer's securities, maximum 30-day WAM). The 2016 money market fund reforms and 2023 reforms further shaped institutional CD demand.", "example": "A corporate treasurer has $50 million in operating cash needed in six months. Treasury bills yield 5.20%; a six-month CD from a AA-rated major bank yields 5.45%; and a six-month investment-grade money market fund yields 5.30%. The treasurer invests $25 million in the bank CD at 5.45% (earning an additional $31,250 versus T-bills over six months) and $25 million in the MMF for daily liquidity flexibility. The CD is not FDIC-insured above $250,000 (far below the $25 million invested), so the treasurer analyzes the bank's credit rating, TLAC adequacy, and regulatory capital ratios before accepting the 25 bps yield premium over T-bills.", "formula": "CD Proceeds at Maturity = Face Value × (1 + Rate × Days/360); Secondary Market Price = Face Value / (1 + Discount Rate × Remaining Days/360)", "formula_latex": null, "interactive_type": "calculator", "calculator_id": null, "related_terms": [ "bankers-acceptance", "commercial-paper", "credit-rating", "credit-risk", "equity-tranche", "exchange", "face-value", "interest-rate", "libor", "liquidity", "municipal-bond", "premium", "repo", "risk-free-rate", "sovereign-bond" ], "backlinks": [ "federal-funds-rate", "high-yield-bond" ], "cross_references": [ "commercial-paper", "credit-rating", "credit-risk", "exchange", "face-value", "interest-rate", "libor", "liquidity", "premium", "repo", "risk-free-rate", "systemic-risk", "yield" ], "tags": [ "level:basic", "cat:fixed-income" ], "asset_classes": [ "fixed-income" ], "regulators": [], "see_also": [], "sources": [], "wordcount": 691, "checksum": "d29624bd3131210b", "version": "2026.05.03", "license": "CC-BY-4.0", "updated_at": "2026-09-07T02:15:24+00:00", "_links": { "self": "https://hedgefund.wiki/api/v1/terms/certificate-of-deposit", "jsonld": "https://hedgefund.wiki/api/v1/terms/certificate-of-deposit?format=jsonld", "markdown": "https://hedgefund.wiki/api/v1/terms/certificate-of-deposit?format=md", "graph": "https://hedgefund.wiki/api/v1/graph/certificate-of-deposit", "category": "https://hedgefund.wiki/api/v1/categories/fixed-income", "schema": "https://hedgefund.wiki/schema/term.schema.json", "html": "https://hedgefund.wiki/#/terms/certificate-of-deposit" } }
