AI Analysis: International transactions in securities, portfolio transactions in Canadian bonds, by type of issuer and transaction, monthly

Executive Summary

Statistics Canada Table 36100031 tracks 38 years of monthly international portfolio transactions in Canadian bonds across 100 time series formed by 10 issuer types and 10 transaction types, revealing a generally positive long-run trend of foreign investment with an average monthly net inflow of $13.9 billion CAD. The data is highly skewed and volatile, with values ranging from -$442,744M to +$455,118M and a median of just $5M versus a mean of $418M, underscoring the outsized influence of episodic large transactions. Outlier analysis identified 14 statistically extreme months (|Z-score| > 2.5) in the net flows series, pointing to sharp market dislocations likely tied to major economic events such as the 2008 financial crisis and the COVID-19 pandemic.

Key Findings

• The dataset contains 45,800 records spanning 458 months (January 1988 to February 2026), organized across 100 unique time series combining 10 issuer types and 10 transaction types.
• Average monthly net flows across all issuers were $13.9 billion CAD, but ranged dramatically from -$87.8 billion to +$158.9 billion in a single month, reflecting extreme volatility over the nearly four-decade period.
• The distribution is heavily right-skewed, with a median of just $5M CAD versus a mean of $418M CAD and a standard deviation of $27,708M, driven by a small number of very large transactions.
• Nearly 45% of all records (44.7%) represent negative values (capital outflows), while the middle 50% of transactions fall within a relatively modest range of -$386M to +$749M, indicating most monthly activity is dwarfed by extreme outliers.
• 14 months were flagged as statistical outliers (|Z-score| > 2.5) in the net flows series, with individual monthly flows ranging from -$26,918M to +$51,266M against a long-run mean of $4,556M and a standard deviation of $8,472M.
• Federal and provincial governments dominate average transaction values by issuer type, while New Issues and Retirements are among the highest-volume transaction categories, reflecting the central role of government debt in Canada's international bond market.
• The correlation heatmap reveals structured relationships between transaction types — particularly between New Issues, Retirements, and Net Flows — providing insight into how foreign investor behavior in Canadian bonds is interconnected across categories.
