Negative Rates Around the World: How One Danish Couple Gets Paid Interest on Their Mortgage

Hans Peter Christensen got some unusual news when he opened his most recent mortgage statement. His quarterly interest payment was negative 249 Danish kroner.
Instead of paying interest on the loan he got a decade ago to buy a house in this northern Denmark city, his bank paid him the equivalent of $38 in interest for the quarter. As of Dec. 31, his mortgage rate, excluding fees, stood at negative 0.0562%.
It has been nearly four years since Denmark entered the world of negative monetary policy, and borrowers and lenders alike are still trying to make sense of the upside-down world it has brought.
“My parents said I should frame it, to prove to coming generations that this ever happened,” said Mr. Christensen, a 35-year-old financial consultant, about his bank statement.
