Modern monetary theory, which seems to be upon us, tells us that it is possible for central banks now, like the Reserve Bank of New Zealand (RBNZ), to print money indefinitely with little consequence.

It supported the Government borrowing to spend money it does not have, and net Government debt relies on interest rates falling, yet the Minister expects them to be raised, in a recent statement in the press at the weekend, peaking at $180 billion in 2025.
