A creditor bringing an action will want interest too. Interest compensates for late payment. For the last 200 years, relief came from statutes. The common law did not recognize a right to pre-judgment interest. That position was relaxed in Sempra Metals v IRC [2008] 1 AC 561. Interest on debts and other claims for breach of contract were legitimised. Plaintiffs can now present claims for compound interest at common law, whereas statutory interest is always simple. Where the interval between cause of action and judgment is long and the sum is large, this is a superior option. In a recent Privy Council decision (Sagicor Bank Jamaica v YP Seaton[2022] UKPC 48), interest calculated on a compound basis was roughly 52 times greater than simple, and roughly 368 times the principal sum.
