Oracles are constructs used in decentralized finance to price assets relative to each other. However, oracles contain defects that could lead to manipulation attacks. Such attacks exploit pricing models embedded within oracles to defraud creators and users. We automatically verify defects, which if mitigated, improves the security of digital currency.

The sharp depreciation of the Canadian dollar and the successful launch of the euro have sparked a lively debate in Canada about the possible benefits of formally adopting the U.S. dollar as our national currency. Some observers have suggested that this debate is largely irrelevant, since Canada is already highly "dollarized." Canadian businesses and households, they assert, often use the U.S. dollar to perform standard money functions in preference to their own currency. Very little evidence has been provided, however, to support these claims. The authors review the available data with a view to drawing some tentative conclusions about the extent to which Canada has already been informally dollarized. The evidence suggests that many of the concerns that have been expressed about the imminent demise of the Canadian dollar have been misplaced. The Canadian dollar continues to be used as the principal unit of account, medium of exchange, and store of value within our borders. Moreover, there is no indication that dollarization is likely to take hold in the foreseeable future. Indeed, in many respects, the Canadian economy is less dollarized now than it was 20 years ago.

The Bank of Canada launched the Bankers’ Acceptance Purchase Facility (BAPF) to ensure that the bankers’ acceptance (BA) market could continue to function well during the financial crisis induced by the COVID‑19 pandemic. We review the impact that the announcement of this facility had on BA yields in the secondary market. We find that BA yield spreads declined by 15 basis points on the day of the announcement and by up to 70 basis points over a longer period. Using an econometric framework, we quantify the effect of the announcement and confirm early assertions presented in the Bank’s 2020 Financial System Review.

Remarks by David Dodge, Governor of the Bank of Canada, to the Canadian Economics Association

We consider ways central banks could adapt in the event of an increased risk of a dash for cash from asset managers. We explore ideas such as new facilities that ease asset managers’ ability to convert existing assets to cash or new assets with liquidity that central banks would guarantee.

An effective pension system enhances economic and financial efficiency. A majority of pension plans in Canada are defined-benefit (DB) plans, but DB plans are under stress from increasing longevity, low long-term interest rates, and the shrinking equity premium. DB plans are vulnerable to such shocks because they are complex financial vehicles, with interdependencies not fully […]

Governor Poloz discusses the recent rise in financial market volatility and low long-term borrowing costs, and what they both mean for central bank credibility.

The LVTS is an electronic network for sending and receiving large-value payments. It is expected to become operational in the first half of 1999. Major chartered banks and other large deposit-taking institutions will provide access to the system for their clients in the financial, corporate and government sectors. Canada’s LVTS exceeds world standards for risk control in large-value systems. The author explains how this is achieved through the netting, bilateral and multilateral credit limits, collateral, and loss-sharing procedures used in the event of a default, and, as a last resort, a guarantee by the Bank of Canada. The LVTS gives participating institutions certainty of settlement for their LVTS positions every day, even if one or more participants default. This greatly reduces systemic risk in the financial system. Moreover, the LVTS supports finality of payment; that is, it makes funds unconditionally and irrevocably available to the receiver. Finality is highly desirable when the amount of the payment is substantial, or when exact timing is critical. Since the LVTS will carry the great majority of the value of all payments in Canada, it should be considered the core of the national payments system.

For many years, the Bank of Canada successfully responded to occasional eruptions in counterfeiting by improving the security features on bank notes. The surge in counterfeiting that occurred while the Bank prepared to launch the Canadian Journey series, however, reflected increasingly rapid advances in computer technology that were changing the counterfeiting environment. The article describes these and other challenges that affected the new series and describes how the Bank developed a comprehensive new approach to its currency program and incorporated the valuable lessons it learned from these challenges. Designed to combat counterfeiting and meet the needs of the public, the new strategy includes increased research and development on new bank note security features, an intensified focus on retailer and public education, and a focus on law enforcement.
