This paper develops Monte Carlo likelihood-ratio tests for determining the number of regimes in Markov switching models. Unlike most existing procedures, which focus on testing one versus two regimes, the proposed methods allow testing an arbitrary number of regimes. They are valid in finite samples, robust to identification problems, and applicable to nonstationary, multivariate, and Markov switching GARCH models.

This note uses detailed expenditure data to decompose Canadian inflation into supply- and demand-driven components. The analysis sheds light on the drivers of post-pandemic inflation and shows that monetary policy primarily affects and responds to demand-driven inflation.

The rise and transformation of Canadian cash ETFs highlight that banking liquidity regulation affects more than bank resilience. By changing the relative attractiveness of deposits and securities, it can shape where asset managers allocate their cash across the financial system.

This note examines whether central clearing of repos benefits non-dealer participants in Canadian fixed-income markets. While prior research highlights lower funding and balance-sheet costs for dealers, less is known about client effects. Understanding these broader implications is important for assessing central clearing’s contribution to market efficiency and resilience.

How do import tariffs affect retail prices? We combine daily product-level posted prices from seven major Canadian retailers with product-level tariff exposure to estimate tariff effects. Prices of tariffed goods rose gradually, peaking at 6% after three months, implying pass-through of roughly one quarter of the 25% tariff.

We construct a macroeconomic estimate of total AI production in the United States, combining inference and R&D/training activities with quality adjustments to account for algorithmic progress. We then develop a nascent framework for "AI GDP" that tracks the AI economy as a coherent whole, complementing traditional national accounts.

This policy note examines how a non-interest-bearing retail central bank digital currency (CBDC) could affect the financial stability of Canada’s systemically important banks during a severe recession. Stress test results show that the banks remain resilient, maintaining key regulatory ratios even under high CBDC demand.

Using simulations of the Bank of Canada’s projection model, we assess inflation risks from greater supply-shock volatility and show that monetary policy faces sharper trade-offs, as stabilizing inflation increasingly comes at the cost of weaker real activity.

The Standing Liquidity Facility (SLF) is one of the Bank of Canada’s least discussed tools—and one of its most important. Embedded directly in Canada’s high value payment system, Lynx, the SLF operates quietly in the background every business day, ensuring the smooth settlement of payments and reinforcing the implementation of monetary policy.

Amid heightened Canada–US trade tensions in 2025, financial markets showed signs that investors had greater difficulty anticipating near-term Bank of Canada interest rate decisions. We look at the Overnight Index Swap prices and intraday Government of Canada yields to identify the main driver of uncertainty around interest rate decisions.
