Jean-Sébastien is a Senior Research Advisor in the Financial Markets Department. His research covers a range of topics in US and Canadian fixed income markets, including the economic determinants of long-term interest rates, the interaction between repo and spot bond markets as well as the role of funding conditions for market liquidity. Jean-Sébastien received his PhD in economic from the Université de Montréal.
Staff Analytical Notes
Bond dealers have traditionally kept bonds in an inventory until clients buy them. But now, dealers have another way to access bonds for their clients: the exchange-traded fund. We discuss this new way to manage bond dealing and what it might mean for bond markets.
The disruption due to COVID-19 reverberated through the bond markets in three phases. In the first phase, dealers met the rising demand for liquidity. In the second, dealers reduced the supply of liquidity, and trading conditions worsened significantly. Finally, the market returned to relative stability following several interventions by the Bank of Canada.
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.
Price controls, or caps, can lead to shortages, as 1970’s gasoline price controls illustrate. One million trades show that the market for borrowing bonds in Canada has an implicit price cap: traders are willing to pay no more than the overnight interest rate to borrow a bond. This suggests the probability of a shortage increases when interest rates are very low.
Canadian interest rates show a secular decline since the 1980s. Long-term survey-based forecasts of interest rates also declined, but less so and were more gradual. Our model-based estimates show an endpoint shifting over time in three phases: a decline between 1990 and 1995, a period of stability between 1996 and 2007, and a further decline since 2008. The current endpoint estimate remains clouded with uncertainty; this is an active area of research.
We identify a few Bank of Canada press releases that had the largest immediate impact on the exchange rate market. We find that volatility increases after these releases, but the effect is short-lived and mostly dissipates after the first hour, on average. Beyond the first hour, the size of the effect is similar to what we observe for other economic releases, such as those for inflation or economic growth data.
We draw a parallel between the dramatic increases of systematic variations in exchange rates and international bank lending. We find that when a country’s currency has a larger share of systematic variations, lending flows by international banks to that country become more sensitive to global lending - they also become more systematic. This parallel is particularly prevalent for large commodity exporters, including Canada. Global financial intermediation may open a new channel between the real economy and exchange rates.
This analytical note evaluates the reliability of proxies for measuring liquidity in Canadian bond markets. We find that price-impact and bid-ask proxies paint a similar picture of evolving liquidity conditions to that obtained from richer measures of liquidity for benchmark Government of Canada bonds.
This analytical note examines how much of the systematic variation in the Canadian dollar is attributable to its sensitivity to commodity prices. We introduce a new “oil” portfolio that captures systematic variations when the exchange rates of commodity exporters and commodity importers move in opposite directions.
In this analytical note we show that the share of the systematic variations in the Canadian dollar has risen significantly in the past two decades. Systematic variations in the exchange rate are shared with other currencies. This parallels the equity market, where variations in the price of a given stock are shared with variations in the prices of other stocks.

This paper investigates how a low or negative overnight interest rate might affect the Canadian repo markets. The main conclusion is that the repo market for general collateral will continue to function effectively.
Staff Working Papers
Dealers connect investors who want to buy or sell securities in financial markets. Over time, dealers and investors form trading networks to save time and resources. An emerging field
of research investigates how networks form.
Specifications of the Federal Reserve target rate that have more realistic features mitigate in-sample over-fitting and are favored in the data.
We study settlement fails for trades in the Government of Canada bond market. We find that settlement fails do not occur independently. Using a novel and comprehensive dataset, we examine three drivers of fails.
We use relative value to measure limits to arbitrage in fixed-income markets. Relative value captures apparent deviations from no-arbitrage relationships. It is simple, intuitive and can be computed model-free for any bond.
The uncertainty around future changes to the Federal Reserve target rate varies over time. In our results, the main driver of uncertainty is a “path” factor signaling information about future policy actions, which is filtered from federal funds futures data.
We greatly expand the space of tractable term-structure models. We consider one example that combines positive yields with rich volatility and correlation dynamics. Bond prices are expressed in closed form and estimation is straightforward.
Following theory, we check that funding risk connects illiquidity, volatility and returns in the cross-section of stocks. We show that the illiquidity and volatility of stocks increase with funding shocks, while contemporaneous returns decrease with funding shocks.
Cochrane and Piazzesi (2005) show that (i) lagged forward rates improve the predictability of annual bond returns, adding to current forward rates, and that (ii) a Markovian model for monthly forward rates cannot generate the pattern of predictability in annual returns.
Most central banks effect changes to their target or policy rate in discrete increments (e.g., multiples of 0.25%) following public announcements on scheduled dates. Still, for most applications, researchers rely on the assumption that the policy rate changes linearly with economic conditions and they do not distinguish between dates with and without scheduled announcements.
We provide a decomposition of nominal yields into real yields, expectations of future inflation and inflation risk premiums when real bonds or inflation swaps are unavailable or unreliable due to their relative illiquidity.
