An independent Alberta could set its own interest rates and monetary policy.
Claimed by: Cited as a benefit of monetary independence
Needs context: Accurate as written, but a key piece of context changes how it reads. How we rate.
Short answer
This depends entirely on the currency choice, and the two are in tension. If Alberta kept using the Canadian dollar, as many separation plans propose, the Bank of Canada would still set interest rates for its own purposes and Alberta would have no vote and no control. To actually run its own monetary policy, Alberta would have to launch its own currency and central bank, build credibility from scratch, and give up the stability of the loonie, while facing higher borrowing costs during the transition. So a sovereign Alberta could in principle control its own interest rates, but only by taking on the very risks that the keep-the-loonie plans are designed to avoid.
What remains uncertain
The claim can be accurate as stated, but important context changes how most people would understand it. The summary above supplies that missing context.
What the evidence shows
A new Alberta currency would mean losing access to Bank of Canada functions and building a central bank and monetary credibility from scratch, with higher borrowing costs in the transition.
On independence the establishment of an Albertan currency and exchange rates would be among the many things not guaranteed and left to negotiation.
