Long dated Treasury yields rose slightly after the U.S. government announced it would buy back some of its own bonds.
What happened
The yield on the 30 year Treasury bond climbed 3.31 basis points to 5.435 percent, while the 20 year yield added 3.44 basis points to 5.495 percent. The move came after the Treasury announced a buyback program, hitting roughly 500 billion dollars of market value. Government bond prices have fallen 1.4 percent over the past week.
Why it matters
A buyback is meant to support the market for older, less liquid bonds, but yields rising on the news means the market read it differently. Higher long term yields raise borrowing costs for mortgages, corporate debt, and the government itself, tightening financial conditions across the economy.
The case against
The rise was modest and could just be a continuation of the week's sell off, not a verdict on the buyback. Philadelphia Fed President Anna Paulson also said the Fed may need to raise rates again, and that hawkish talk is a cleaner, simpler explanation for why bond prices fell.
What settles it
Whether the Treasury buyback operations actually draw strong demand when they begin, or if the market keeps pushing yields higher regardless.
