Convertible bonds, warrants and contingent convertibles

A convertible lets the investor swap the bond for a fixed number of shares, so it trades like a bond when the share price is low and like the shares when it is high; a CoCo converts automatically on the downside when a bank's capital runs short.

In short

  • A convertible bond gives holders the right to exchange it for the issuer's common shares at the conversion price.
  • Conversion ratio = par ÷ conversion price; conversion value = conversion ratio × current share price.
  • The conversion price is typically set at a premium to the share price at issue; in return investors accept a very low coupon or yield.
  • Share price far below conversion price → trades like a straight bond; far above → tracks conversion value.
  • Warrants are attached, separately tradable options to buy shares.
  • CoCos convert (or are written down) automatically if bank capital falls below a regulatory minimum; they pay a higher yield.
