Supply fears start to hit Treasuries

FT

The bond vigilantes are finally flexing their muscles. A long period of stability for the US government bond market showed signs of cracking this week as a lack of investor appetite for new debt sent the benchmark 10-year yield to its highest level since last June.

For more than a year, analysts have been warning that record sized debt sales by the US Treasury were at odds with a 10-year yield sitting comfortably below 4 per cent. This week, the yield on 10-year notes jumped from 3.65 per cent to a peak of 3.92 per cent on Thursday. On Friday it was 3.87 per cent.

Falling inflation, rising unemployment, the housing market slump, the Federal Reserve’s policies of a near zero overnight borrowing rate and its purchase of up to $1,700bn in bonds have all helped keep Treasury yields near historic lows.

But this week the mood shifted as yields for $118bn of new US debt were much higher than forecast, sparking overall selling of Treasuries. Sentiment also deteriorated in the UK bond market after the government’s budget ahead of a general election expected in May failed to resolve doubts over future spending and debt reduction.

The term “bond vigilantes” was coined in the 1980s when bond investors pushed up long-term yields to force central banks into taking action to curb inflation. This time, bond investors are less worried about inflation: they are fretting about huge fiscal deficits and the looming bond supply needed to finance them.
