As the Government of Canada’s bond issuance has surged over the past five years, so too has hedge fund participation in federal bond auctions. Once marginal players, hedge funds are now the second-largest investor group after dealers— with an allocation topping 40% in 2024.
Their growing presence has supported auction performance during a period of rapid debt expansion. But a Bank of Canada staff discussion paper stresses that this shift brings new risks.
For policy-makers, the key takeaway is that although the increased participation and competitive bidding of hedge funds at GoC bond auctions is a welcome development that has supported continued strong auction performance amid rising issuance, this trend comes with risks.
Auctions have performed well despite increasing Government debt issuance and stock
Between FY 2019–20 and FY 2024–25, Government of Canada (GoC) nominal bond issuance nearly doubled—to $237 billion from $122 billion. The total stock of ballooned to $1.16 trillion from $597 billion over the same period.

Despite the issuance increase, auctions have continued to perform well. A key factor: hedge fund participation rose significantly starting in 2020, accounting for more than 40% of allocation by 2024.
Hedge funds are also more likely than other investor types to bid at lower yields (higher prices), making their auction demand relatively price-inelastic.
Why Hedge Funds Respond to Higher Bond Issuance
Why Hedge Funds Respond to Higher Bond Issuance
Identify Market Mispricing
Hedge funds seek to identify perceived mispricing in the market, such as between GoC bonds and futures, CAD spread products, or other sovereign bonds.
Their priority is taking large-volume positions to maximize profits from perceived mispricing, rather than competing over a few basis points on a particular transaction.
Take Large Positions
They take substantial positions on perceived mispricing, using significant leverage via repos to scale profits from small basis differences.
Benefit from Larger Debt Stock
A larger GoC debt stock enhances hedge funds’ ability to take long positions in large sizes and provides a larger base of assets to repo out to fund their positions.
Primary Market is Cost effective
The primary market offers a cost-effective means to attain large GoC bond positions, avoiding the price impact of large secondary market transactions.
Increasing Allocation to Hedge Funds
2010: Minimal hedge fund allocation at GoC auctions
2015: Growing hedge fund presence as they discover relative value opportunities
2020: Significant increase in hedge fund allocation as government debt expands
2024: Hedge funds now receive over 40% of auction allocation
It has partly masked the somewhat concerning trend of dealer and real money capacity not keeping pace with that issuance.
It has created a vulnerability through increased pressure on the repo market, reducing capacity there. Any major loss in market capacity could compromise Canada’s fundamental debt management objectives of raising stable and lowcost funding to meet its financial requirements and maintaining a wellfunctioning market for GoC securities.
A double-edged sword
Benefits
- Supports strong auction performance amid rising issuance
- Provides cost-effective debt distribution for the government
- Enhances market liquidity in normal times
Emerging Risks
Investor concentration
Hedge funds’ allocation at auctions has increased rapidly, while the share of other investors—such as pension funds and insurance companies—has remained flat or declined. This raises questions about the resilience of auction demand over time.
Repo Market Pressure
Hedge fund strategies often involve leveraged trades (e.g. cash-futures basis, asset swaps) funded through the repo market. Their demand for repo financing has contributed to upward pressure on CORRA, Canada’s overnight repo rate. Because their models are volume-driven, they tend to rely on large positions and substantial use of dealer balance sheets.
Exit Risk
As foreign, non-bank investors, hedge funds are more mobile than domestic realmoney buyers. Their participation could decline in periods of stress—particularly in Canada-specific events—potentially leading to lower coverage ratios and higher yields at auction.
