One of the oldest ways of creating money is of course lending and mortgages. Go to the bank to buy your dream house, and they transfer a sum of money to you, created out of thin air, to enable you to buy your new property. Because interest rates have gotten so low, real estate prices went up. The price to pay is when the constant buildup of expectations (companies’ profits, stock market, real estate value) stagnates for whatever reason, like… Brexit.
