Market Mechanics: Canadian Provinces, Pre-funding, and the quiet flattening of ASW Curves

A recent feature of the Canadian rates market has been the steady flattening of asset swap (“ASW”) curves for the larger provincial issuers.  This development is not a reflection of shifting macroeconomic expectations or changing credit fundamentals.  Instead, it is being driven by funding mechanics, offshore issuance decisions, and sustained demand for highly rated spread product.

Unlike most sovereign markets, Canadian provinces account for a substantial share of total public-sector borrowing in Canada, exceeding that of the federal government.  Over time, provinces have recognised that relying exclusively on the domestic market can place pressure on local funding conditions, pushing borrowing costs higher, particularly at longer maturities.  As a result, provincial issuers actively manage their funding across global markets, accessing offshore markets when conditions are attractive.

Cross-currency funding plays a central role in this approach.  Provinces closely monitor cross-currency basis levels and issue in foreign currencies when swap-adjusted funding costs are favourable.  The US dollar and euro markets are partial exceptions.  Even when funding costs are marginally higher, provinces are often willing to pay a modest premium to remain regular, well-recognised borrowers in the deepest and most liquid global markets.  Maintaining this presence preserves funding flexibility during periods of market stress, when access to domestic markets alone may be insufficient.

This flexibility has been evident in recent cycles.  When AUD/CAD cross-currency conditions were particularly attractive two years ago, nearly all major provinces issued sizeable ten-year Australian dollar bonds.  As those favourable cross-currency economics have deteriorated, so too has Australian dollar issuance of Canadian debt.  This pattern reflects a consistent approach – issuance decisions follow funding efficiency and investor depth, not duration or macro views.

The current environment has been especially supportive for provincial issuers.  Global demand for highly rated debt offering a modest yield premium remains exceptionally strong, particularly from outright buyers seeking high-quality spread products.  Canadian provinces have benefited from this demand, allowing a significant portion of annual funding programmes to be completed early in the fiscal year, and in some cases extending into funding for the following year.

This pre-funding behaviour has important second-order effects.  With funding secured well ahead of the 31 March fiscal year-end, the risk of late-cycle issuance pressure has diminished. Domestic bond supply has therefore been materially reduced at the same time that demand from Canadian bank balance sheets and other real-money investors has remained strong. The combination of constrained supply and persistent demand has contributed to a gradual flattening of provincial ASW curves, particularly for larger and more liquid issuers.

Markets tend to reward disciplined pre-funding, as it signals prudent liquidity management, responsiveness to investor demand, and lower refinancing risk.  For Canadian provinces, this has reduced reliance on late-cycle domestic issuance, helping to support pricing and preserve favourable funding conditions when domestic demand has been strongest.

These dynamics are not driven by macro expectations, but by issuance timing, offshore funding choices, and investor positioning.  They continue to reshape relative value along provincial curves, highlighting how issuer behaviour and market structure can be as influential as fundamentals in determining price.

As in many fixed income markets today, some of the most persistent opportunities sit beneath the surface, shaped by market mechanics and by how borrowers choose to fund themselves, rather than by where the macro cycle appears to be heading.
