This is a tougher question to answer than it seems.
A BBC story put a loaf's price at 65 million Zimbabwean dollars.
The official exchange rate is about 29,774 Zimbabwean dollars to the Loonie, according to Yahoo! Finance's currency calculator.
That would make a loaf of bread worth ... $2,183.
A decent loaf of multigrain at the Kensington Market bakery here is $2.89.
The National Post wrote this on April 16 in an article entitled It's not just inflation, it's hyperinflation!
As if the appearance of newly-minted $50,000,000 bank notes worth all of about US$1.20, or the equivalent of three loaves of bread ...
That would make the price of a loaf of bread to be about 40 cents (the loonie was pretty close to par today), and would mean a real exchange rate of 41,666,666.67 Zimbabwean dollars to the Loonie.
