What do high-frequency expenditure network data reveal about spending and inflation during COVID‑19?

Staff Analytical Note 2020-20 Kim Huynh, Helen Lao, Patrick Sabourin, Angelika Welte
The official consumer price index (CPI) inflation measure, based on a fixed basket set before the COVID 19 pandemic, may not fully reflect what consumers are currently experiencing. We partnered with Statistics Canada to construct a more representative index for the pandemic with weights based on real-time transaction and survey data.

2018 Merchant Acceptance Survey

Staff Analytical Note 2019-31 Kim Huynh, Gradon Nicholls, Mitchell Nicholson
In 2015, the Bank of Canada surveyed merchants and found that cash was nearly universally accepted (Fung, Huynh and Kosse 2017). Since 2015, retail payments in Canada have become increasingly digitalized, as many Canadians have adopted digital payment innovations like contactless cards and Interac e-Transfer.

Bitcoin Awareness and Usage in Canada: An Update

Staff Analytical Note 2018-23 Christopher Henry, Kim Huynh, Gradon Nicholls
The results of our 2017 Bitcoin Omnibus Survey (December 12 to 15, 2017) when compared with those from 2016 show that Bitcoin “awareness” increased from 64 to 85 per cent, while ownership increased from 2.9 to 5.0 per cent. Most Bitcoin purchasers are using the cryptocurrency as an investment and not as a means of payment for goods or services.

Cash and COVID-19: The impact of the second wave in Canada

Staff Discussion Paper 2021-12 Heng Chen, Walter Engert, Marie-Hélène Felt, Kim Huynh, Gradon Nicholls, Daneal O’Habib, Julia Zhu
The COVID-19 pandemic significantly increased the demand for cash. Cash in circulation increased sharply from March through December 2020, particularly in the early months of this period. Although use of electronic methods of payment also increased significantly, cash use for payments remains high for low-value transactions and among certain demographic groups.

An Exploration of First Nations Reserves and Access to Cash

Staff Discussion Paper 2021-8 Heng Chen, Walter Engert, Kim Huynh, Daneal O’Habib
Adequate cash distribution is one the Bank of Canada’s core interests. Canadians’ ability to access cash influences the Bank’s thinking on issuing a central bank digital currency. We provide a perspective on these issues by exploring access of First Nations reserves to cash.

Cash and COVID-19: The Effects of Lifting Containment Measures on Cash Demand and Use

Staff Discussion Paper 2021-3 Heng Chen, Walter Engert, Kim Huynh, Gradon Nicholls, Julia Zhu
Using Bank Note Distribution System data on the demand for cash up to September 2020, we find that demand was strong. This is true even though cash use for payments declined early in the pandemic. When mobility restrictions and lockdown measures were eased, cash use for payments increased sharply but remained less popular than electronic methods of payment.

Cash and COVID-19: The impact of the pandemic on demand for and use of cash

Staff Discussion Paper 2020-6 Heng Chen, Walter Engert, Kim Huynh, Gradon Nicholls, Mitchell Nicholson, Julia Zhu
Consumer spending declined significantly during the recent COVID-19 pandemic. This negative shock likely reduced spending across all methods of payment (cash, debit, credit, etc.). The mix of payment methods consumers use could also be affected. We study how the pandemic has influenced the demand for and use of cash. We also offer insights into the use of other payment methods, such as debit and credit cards.

Bitcoin Awareness and Usage in Canada

Staff Working Paper 2017-56 Christopher Henry, Kim Huynh, Gradon Nicholls
There has been tremendous discussion of Bitcoin, digital currencies and FinTech. However, there is limited empirical evidence of Bitcoin’s adoption and usage. We propose a methodology to collect a nationally representative sample using the Bitcoin Omnibus Survey (BTCOS) to track the ubiquity and usage of Bitcoin in Canada.

Acceptance and Use of Payments at the Point of Sale in Canada

Bank of Canada Review - Autumn 2017 Ben Fung, Kim Huynh, Anneke Kosse
Merchants universally accept cash. Consumers widely hold cash but also carry debit and credit cards. The cost of using a method of payment has only a small influence on which method consumers use. Large merchants accept all payments, while only two-thirds of small and medium-sized businesses accept credit cards. Merchants report that credit cards are the costliest payment method compared with cash and debit cards. However, costs are not the only consideration. Merchant acceptance of credit accounts for the many con-sumers that want to use credit cards. This interaction between consumers and merchants is known as network externalities.

The Use of Cash in Canada

Bank of Canada Review - Spring 2015 Ben Fung, Kim Huynh, Gerald Stuber
The Bank of Canada’s 2013 Methods-of-Payment Survey indicates that the share of cash in the overall number of retail transactions has continued to decrease, mainly because of increased use of contactless credit cards. The share of cash in the total value of retail transactions was virtually unchanged from 2009 to 2013. In particular, the value share of cash transactions above $50 increased. Automated banking machines (ABMs), still the major source of cash for Canadians, were used less often in 2013 than in 2009. Cash use in Canada is broadly similar to that in Australia and the United States.

The Changing Landscape for Retail Payments in Canada and the Implications for the Demand for Cash

Bank of Canada Review - Autumn 2012 Carlos Arango, Kim Huynh, Ben Fung, Gerald Stuber

Over the past 20 years, there has been a major shift away from the use of paper-based retail payment instruments, such as cash and cheques, toward electronic means of payment, such as debit cards and credit cards. Recent Bank of Canada research on consumers’ choice of payment instruments indicates that cash is frequently used for transactions with low values because of its speed, ease of use and wide acceptance, while debit and credit cards are more commonly used for transactions with higher values because of perceived attributes such as safety and record keeping. While innovations in retail payments currently being introduced into the Canadian marketplace could lead to a further reduction in the use of cash over the longer term, the implications for the use of cash of some of the structural and regulatory developments under way are less clear.
