We investigate whether hedge funds contributed to Government of Canada bond market illiquidity at the onset of the Middle East war in early 2026. We find no evidence they did. Hedge funds remained active in primary auctions, while their secondary market trading remained broadly consistent with their usual relative-value strategies.

We measure the contribution to inflation from the growth in markups of Canadian firms. The dynamics of inflation and markups suggest that changes in markups could account for less than one-tenth of inflation in 2021. Further, they suggest that peak inflation was driven primarily by changes in the costs of firms.

We introduce generalized autoregressive gamma (GARG) processes, a class of autoregressive and moving-average processes in which each conditional moment dynamic is driven by a different and identifiable moving average of the variable of interest. We show that using GARG processes reduces pricing errors by substantially more than using existing autoregressive gamma processes does.

We examine the effects of monetary policy shocks on the Canadian housing market. Using high-frequency surprises around fixed announcement dates as an instrument in a Bayesian VAR, we estimate the responses of house prices, housing starts, building permits, resales, inventories, and mortgage purchases to a contractionary monetary policy shock. An increase in the policy rate leads to a substantial and persistent decline in average house prices. Housing starts and building permits fall, but their implied effects on the future housing stock are both slow and modest. Interpreted through the lens of market equilibrium, these results are most consistent with a stronger response of housing demand than housing supply.

To address the challenges posed by global systemically important banks (G-SIBs), the Basel Committee on Banking Supervision recommended an “additional loss absorbency requirement” for these institutions. Along these lines, I develop a microfounded design of capital surcharges that target the interconnectedness component of systemic risk.

We find that the rise in Government of Canada debt issuance correlates to growing participation of hedge funds in bond auctions since 2020. This increased participation supports the cost-effective distribution of Canada’s debt, but it also represents a potential vulnerability because hedge funds have a greater flight risk than other investor types.

We show how participants in Canada’s new high-value payment system save liquidity by exploiting the new gridlock resolution arrangement. The findings have important implications for the design of these systems and shed light on financial institutions’ liquidity preference.

Optimal coordination of monetary and macroprudential policies implies higher risk weights on (safe) bonds any time that banks are required to hold additional capital buffers. Coordination also implies a somewhat tighter monetary-policy stance whenever such capital buffers are released.

In this study, we enhance Markowitz portfolio selection with graph theory for the analysis of two portfolios composed of either EU or US assets. Using a threshold-based decomposition of their respective covariance matrices, we perturb the level of risk in each portfolio and build the corresponding sets of graphs.
