Profound shifts in the world economy could make inflation volatile for years to come, complicating efforts to control prices, but sticking with inflation-targeting regimes is still the best option, European Central Bank President Christine Lagarde said on Friday.

Canadian inflation matched the central bank’s target last month for the first time in more than three years, smoothing the road for further cuts in interest rates.

With inflation subsiding, the European Central Bank is cutting its benchmark interest rate to prop up tepid growth with lower borrowing costs for companies and home buyers.
