Is This Normal? The Cost of Assuming that Derivatives Have Normal Returns
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. -
Decomposing Large Banks’ Systemic Trading Losses
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. -
Reaching for yield or resiliency? Explaining the shift in Canadian pension plan portfolios
“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. -
Interbank Asset-Liability Networks with Fire Sale Management
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? -
Extreme Downside Risk in Asset Returns
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. -
Borrowing Costs for Government of Canada Treasury Bills
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. -
Relative Value of Government of Canada Bonds
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. -
