The Cost of the Government Bond Buyback and Switch Programs in Canada

Staff Analytical Note 2018-41 Bo Young Chang, Jun Yang, Parker Liu
This note examines the costs of the Government of Canada bond buyback and switch programs between 1998 and 2016.

Equity Option-Implied Probability of Default and Equity Recovery Rate

Staff Working Paper 2016-58 Bo Young Chang, Greg Orosi
There is a close link between prices of equity options and the default probability of a firm. We show that in the presence of positive expected equity recovery, standard methods that assume zero equity recovery at default misestimate the option-implied default probability.

Monitoring Shadow Banking in Canada: A Hybrid Approach

In Monitoring Shadow Banking in Canada: A Hybrid Approach, Bo Young Chang, Michael Januska, Gitanjali Kumar and André Usche discuss how lending that occurs outside the traditional banking system provides benefits to the economy but must be monitored carefully for potential financial sector vulnerabilities. They describe how the Bank defines and measures shadow banking and how it assesses vulnerabilities in the sector, using an approach that examines both markets and entities.

Measuring Uncertainty in Monetary Policy Using Realized and Implied Volatility

Uncertainty surrounding the Bank of Canada’s future policy rates is measured using implied volatility computed from interest rate options and realized volatility computed from intraday prices of interest rate futures. Both volatility measures show that uncertainty decreased following major policy actions taken by the Bank in response to the 2007–09 financial crisis. Findings also indicate that, on average, uncertainty decreases following the Bank’s policy rate announcements.
