The formulation of monetary policy at the Bank of Canada relies on the analysis of a broad set of economic information. Greater availability of immediate and detailed information would improve real-time economic decision making. Technological advances have provided an opportunity to exploit “big data” - the vast amount of digital data from business transactions, social media and networked computers. Big data can be a complement to traditional information sources, offering fresh insight for the monitoring of economic activity and inflation.

How does the transmission of monetary policy change when a central bank digital currency (CBDC) is introduced in the economy? Does CBDC design matter? We study these questions in a general equilibrium model with nominal rigidities, liquidity frictions, and a banking sector where commercial banks face a leverage constraint.

As the holiday season approaches, our attention turns naturally to the home front. Accordingly, my comments this afternoon will focus on households. I would like to concentrate in particular on the implications of Canadian household finances for financial stability in our country.

Governor Mark Carney discusses current financial system reform initiatives in a speech to the Institute of International Finance.

In this issue of the Financial System Review, the Governing Council judges that the risks to the stability of Canada’s financial system remain high, as in December. The sources of the key risks are broadly the same as those highlighted at that time and emanate primarily from the external environment.

We outline possible system architectures for an online retail central bank digital currency (CBDC) and identify one well-suited for basic payments. We analyze OpenCBDC 2PC, a representative system, finding such designs to be feasible, although some areas require further investigation. Our framing highlights other promising architectures for a retail CBDC.

It goes without saying that a sound system of private pensions is important from the perspective of pensioners who rely on a given plan for their retirement income. For firms, a pension plan can help to attract and retain staff, and so the business community also counts on a sound pension system.

Innovations in basic information technologies, in payment applications, and in the availability of global markets, as well as substantial changes in financial sector policy, have fundamentally changed how the retail payments system in Canada operates. Principally, the volume and types of electronic payments have grown, and there is increased participation by diverse groups of financial and non-financial institutions as providers of retail payment services. The resulting policy problem for payment systems is how best to benefit from efficiency gains while managing payment risks. O'Connor examines the effect of the technological and legislative changes and the initiatives developed by the public and private sectors in such areas as the market arrangements for services; customer risks and costs for settling large-value retail payments; the security of payment information and the efficiency with which it is transmitted; and the effects of differing regulatory regimes on competition among providers of retail payment services.

Privacy is a key aspect of a potential central bank digital currency system. We outline different technical choices to enact various privacy models while complying with the appropriate regulations. We develop a framework to evaluate privacy models and list key risks and trade-offs in privacy design.
