Wall Street Dealers Become Bit Players in US Bond Sales

Wall Street bond dealers are moving rapidly to the sidelines of US Treasury auctions — the very activity that defines their status at the heart of the world’s biggest bond market.

Until 2008, the roughly two dozen “primary dealers” designated by the Federal Reserve Bank of New York had a virtual stranglehold on the distribution of new US government debt, capturing at least 60% of every 10-year note auction and usually more than 80%.

But by last year their role was starkly smaller: The average was under 17% and, in one auction, was as low as 7.4%. The trend is the same for the Treasury’s other notes, bonds, and inflation-protected securities. Two auctions last week produced record low awards to those primary dealers.

The diminished sway of the once-dominant players stems in part from institutional investors that have seized on the ability to buy directly from the Treasury, bypassing the firms that snap them up and resell them to customers. It’s also a side effect of the US government’s burgeoning debt, which swelled faster than the dealers’ capacity to absorb it all and left others picking up the slack.

“The US Treasury market has evolved to include a more diverse set of market participants that is increasingly driven by investor, rather than dealer, trading,” said Kevin McPartland, head of research for market structure and technology at Coalition Greenwich.

The trend has contributed to the deep reduction in the Treasury market’s liquidity, or the ability to buy or sell big blocks of bonds without moving prices. While other factors have also played a role in the liquidity drop — including a surge in volatility — the auction figures show how the Wall Street giants have scaled-back their role in a market where they have been counted on to step in to soften the impact of selloffs.
