Japanese families seem to have a sudden affinity for home safes. According to the Tokyo-based manufacturer Eiko, shipments have doubled since last fall. And in Germany, insurer Munich Re has stashed some 10 million euros ($11.4 million) worth of its own cash into vaults.
Why the squirreling? One possible reason is the creeping imposition of negative interest rates across the world, which could make it more rewarding to bypass banks—and a safe or vault is, well, more secure than a mattress.
Welcome to the upside-down world of modern monetary policy. In this new reality, borrowers get paid and savers penalized. Almost 500 million people in a quarter of the global economy now live in countries where interest rates measure less than zero. That would’ve been an almost unthinkable phenomenon before the 2008 financial crisis, and one major economies didn’t seriously consider until two years ago, when the European Central Bank first partook in the experiment. Now the ECB and the Bank of Japan are diving deeper into the sub-zero world as they seek more ways to spark inflation.
