When a Bank of Canada research paper wanted to illustrate how bond markets could be disrupted by flows, it chose a telling example: a hedge fund suddenly selling Canadian government debt. The choice was no accident.
Over the past 15 years, international hedge funds have become increasingly important players in Canada’s government bond auctions, now accounting for up to 40 per cent of certain newly issued bonds for certain tenors – up from zero. But this shift masks another trend: dealer cash and repurchase agreement (repo) balance sheet capacity has had hard time keeping pace with rising debt issuance. This capacity challenge has contributed to a higher reliance on hedge funds.
There is a positive side to this trend: the rise of hedge funds in government bond auctions has helped keep borrowing costs low through competitive bidding, improving market liquidity.
The downside is the added vulnerability related to the fact that most hedge funds are international players susceptible to exit quickly when conditions change: “without organic commitment to the Canadian market, they could be more likely to pull back during a Canada-specific stress event,” Bank of Canada researchers noted.
With the Office of the Parliamentary Budget Officer (PBO) estimating the federal government’s debt servicing costs at $53.5 billion for 2024-25, even small changes in borrowing costs can have sizeable impacts.

The central bank’s research shows that if investors holding just 1 per cent of total government debt suddenly sold their positions, it could push down bond prices by 0.2 per cent over three months. This refers to the average price of 10-year government bonds over one quarter.
History has shown how quickly hedge funds can unload large positions. As Reuters reported in April this year, hedge funds played a central role in the U.S. Treasury selloff that followed President Donald Trump’s announcement of tariffs of over 100 per cent on China.
In Canada, non-residents – including foreign central banks, sovereign wealth funds, and hedge funds – held 48.2 per cent of publicly available federal bonds in the first quarter of this year. When combining non-residents and Canadian pension funds, the share was 62 per cent. Domestic mutual funds, insurers, and banks held just 20 per cent.
This concentration means Canada’s borrowing costs are increasingly determined by international investors who may have little structural commitment to the Canadian market.
Yet even if a sudden hedge fund exit happened, the “persistence of flows” would matter as market participants are typically “more willing to accommodate temporary imbalances, knowing they will soon reverse.”
Short-term volatility alone is after all a normal part of financial market life. But in an era where economic security increasingly intertwines with national security, heavy reliance on international capital to finance the country’s debt represents a source of vulnerability worth paying attention to.
