We find that foreign central banks own a large share of Government of Canada (GoC) bonds and tend to hold their positions for longer than other types of asset managers. This buy-and-hold behaviour could offer benefits. For example, foreign central banks may be less likely than other asset managers to sell bonds and add to strains on market liquidity in periods of turmoil. However, foreign central banks’ buy-and-hold behaviour combined with their minimal lending of GoC bonds in securities-financing markets, as observed in our available data, can potentially lower liquidity because fewer GoC bonds are available for others to transact in secondary markets. Indeed, we find that higher levels of foreign central banks’ GoC bond holdings are related to lower liquidity.

Derivatives exchanges often determine collateral requirements, which are fundamental to market safety, with dated risk models assuming normal returns. However, derivatives returns are heavy-tailed, which leads to the systematic under-collection of collateral (margin). This paper uses extreme value theory (EVT) to evaluate the cost of this margin inadequacy to market participants in the event of default.

Do banks realize simultaneous trading losses because they invest in the same assets, or because different assets are subject to the same macro shocks? This paper decomposes the comovements of bank trading losses into two orthogonal channels: portfolio overlap and common shocks.

“Reach for yield”—This is the commonly heard explanation for why pension plans shift their portfolios toward alternative assets. But we show that the new portfolios also hold more bonds, offer lower average returns and produce smaller and less volatile solvency deficits. These shifts are part of a broader strategy to reduce solvency risk.

Raising liquidity when funding is stressed creates pressure on the financial market. Liquidating large quantities of assets depresses their prices and may amplify funding shocks. How do banks weathering a funding crisis contribute to contagion risk?

Financial markets can experience sudden and extreme downward movements. Investors are highly concerned about the performance of their assets in such scenarios. Some assets perform badly in a downturn in the market; others have milder reactions.

The cost of borrowing Government of Canada treasury bills (t-bills) in the repurchase (repo) market is mainly explained by the relationship between the parties involved. Some pairs of parties conduct most of their repos for t-bills rather than bonds, and at relatively high borrowing costs. We speculate that these pairs have formed a mutually beneficial service relationship in which one party consistently receives t-bills, while the other receives cash at a relatively cheap rate.

Government of Canada bonds in circulation that promise very similar payoffs can have different prices. We study the reason for these differences. Bonds that trade more often and earn high rental income in the repurchase agreement (repo) market tend to have higher prices. Bonds with longer tenors and times to maturity tend to have lower prices. This contrast between cheap and expensive bonds is important because trading volume and rental income can change rapidly, unlike tenor and time to maturity, which are stable.

This report presents the details of a new semi-annual survey that will improve the Bank of Canada’s surveillance across the financial system and deepen efforts to engage with financial system participants. The survey collects expert opinions on the risks to and resilience of the Canadian financial system as well as on emerging trends and financial innovations. The report presents an overview of the survey and provides high-level results from the spring 2018 survey.

We examine the effect of ex-post information contagion on the ex-ante level of systemic risk defined as the probability of joint bank default.
