The Bank of England is about to become the fifth major central bank to put negative interest rates under consideration.
When interest rates hit 0%, there is very little incentive to repay your debts.
Now that central banks have officially assumed their role of buyers of last resort, there is virtually no limit to how much debt can be monetized, and in this new normal, governments seem to be able to keep refinancing their debts forever.
So, in this new abnormal environment, would you prefer to put your savings...
... in government bonds that yield zero and have an infinite supply,
... in gold that also yields zero but has a highly limited supply?
From this perspective, we can safely bet that we will see more and more physical gold being added to private portfolios.
