The Financial Post reports on why the sharp escalation of global bond yields in recent weeks raises the prospect we may be in the middle of a structural shift to a world of permanently higher borrowing costs.

The Post says that, "As a guardrail for policy, former Bank of Canada Governor David Dodge has proposed a 10 percent prudence rule as an anchor for the federal government, whereby debt service charges are kept at no more than one-tenth of revenue.
The March budget had projected interest payments would remain below that threshold throughout the forecasting horizon. But the increase in global bond yields has put it on a path to breach Dodge's rule, perhaps permanently, without additional fiscal adjustments.
