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.

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.

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).

Banking Regulation and Market Making

Staff Working Paper 2017-7 David A. Cimon, Corey Garriott
We present a model of market makers subject to recent banking regulations: liquidity and capital constraints in the style of Basel III and a position limit in the style of the Volcker Rule.

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.
