Staff Analytical Notes

Will exchange-traded funds shape the future of bond dealing?

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.

Customer Liquidity Provision in Canadian Bond Markets

Staff Analytical Note 2018-12 Corey Garriott, Jesse Johal
This analytical note assesses the prevalence of liquidity provision by institutional investors in Canadian bonds. We find that the practice is not prevalent in Canada. Customer liquidity provision is more prevalent for less liquid bonds, on days when liquidity is already expensive or when there are larger trading volumes. In our interpretation, Canadian dealers draw on customer liquidity as a supplementary source of liquidity and only when necessary, given its cost.

The Impacts of Monetary Policy Statements

Staff Analytical Note 2017-22 Bruno Feunou, Corey Garriott, James Kyeong, Raisa Leiderman
In this note, we find that market participants react to an unexpected change in the tone of Canadian monetary policy statements. When the market perceives that the Bank of Canada plans to tighten (or alternatively, loosen) the monetary policy earlier than previously expected, the Canadian dollar appreciates (or depreciates) and long-term Government of Canada bond yields increase (or decrease). The tone of a statement is particularly relevant to the market when the policy rate has been unchanged for some time.

Do Canadian Broker-Dealers Act as Agents or Principals in Bond Trading?

Staff Analytical Note 2017-11 Daniel Hyun, Jesse Johal, Corey Garriott
Technology, risk tolerance and regulation may influence dealers to reduce their trading as principals (using their own balance sheets for sales and purchases of securities) in favour of agency trading (matching client trades).

Staff Discussion Papers

Alternative Futures for Government of Canada Debt Management

This paper presents four blue-sky ideas for lowering the cost of the Government of Canada’s debt without increasing the debt’s risk profile. We argue that each idea would improve the secondary-market liquidity of government debt, thereby increasing the demand for government bonds and thus lowering their cost at issuance.

Government of Canada Fixed-Income Market Ecology

Staff Discussion Paper 2018-10 Léanne Berger-Soucy, Corey Garriott, André Usche

This discussion paper is the third in the Financial Markets Department’s series on the structure of Canadian financial markets. These papers are called “ecologies” because they study the interactions among market participants, infrastructures, regulations and the terms of the traded contract itself.

Canadian Repo Market Ecology

Staff Discussion Paper 2016-8 Corey Garriott, Kyle Gray
This is the first of the Financial Markets Department’s descriptions of Canadian financial industrial organization. The document discusses the organization of the repurchase-agreement (repo) market in Canada.

Staff Working Papers

Trading on Long-term Information

Staff Working Paper 2020-20 Corey Garriott, Ryan Riordan
Investors who trade based on good research are said to be the backbone of stock markets: They conduct research to discover the value of stocks and, through their trading, guide financial prices to reflect true value. What can make their job difficult is that high-speed, short-term traders could use machine learning and other technologies to infer when informed investors are trading.

High-Frequency Trading and Institutional Trading Costs

Staff Working Paper 2018-8 Marie Chen, Corey Garriott
Using bond futures data, we test whether high-frequency trading (HFT) is engaging in back running, a trading strategy that can create costs for financial institutions. We reject the hypothesis of back running and find instead that HFT mildly improves trading costs for institutions.

Banking Regulation and Market Making

Staff Working Paper 2017-7 David A. Cimon, Corey Garriott
We model how securities dealers respond to regulations on leverage, position and liquidity such as those imposed by the Basel III framework. We show that while asset prices exhibit greater price impact, bid-ask spreads do not change and trading volumes may even increase.

Options Decimalization

Staff Working Paper 2016-57 Faith Chin, Corey Garriott
We document the outcome of an options decimalization pilot on Canada’s derivatives exchange. Decimalization improves measures of liquidity and price efficiency. The impact differs by the moneyness of an option and is greatest for out-of-the-money options.
