2. Bond Pricing, Yield Hierarchy & the See-Saw Rule

Pricing RelationshipYield Hierarchy (Lowest to Highest)Coupon vs Market RateCall Price vs Market
Bond at Par ($1,000)Nominal = Current = YTM = YTC (All equal)Coupon = Market Interest RateCall price typically par plus call premium
Bond at Discount (< $1,000)Nominal < Current < YTM < YTCCoupon < Market Interest RateYield to Call (YTC) is highest yield
Bond at Premium (> $1,000)YTC < YTM < Current < NominalCoupon > Market Interest RateYield to Call (YTC) is lowest yield (quote YTC!)
๐Ÿ’ก Pro Tip:Exam Rule: Always quote the LOWER of YTM or YTC to a customer purchasing a bond (Yield to Worst). On premium bonds, quote YTC.
