10-30 Year Bond AuctionsKeep an eye on these auctions and the impact it will have on bond rates and the tech vs value trade. A pair of long-dated Treasury sales set for this week could help reignite this years rapid run-up in yields that has sent some frothier parts of the equity markets tumbling. The turbulence has sparked renewed debate about potential plumbing problems in the deep well of the U.S. government bond market, a linchpin of global finance. An auction for 10-year Treasury notes on Wednesday and 30-year Treasury bonds on Thursday will draw focus among investors wary that markets may be ill-prepared to handle the weight of burgeoning fiscal deficits, as the Biden administration and Congress push forward with another $1.9 trillion stimulus package. The bond market is starting to get concerned with how strong demand will be for these auctions, especially considering how brutal the 7-year auction went two weeks ago, said Edward Moya, senior analyst at OANDA. Until late February, market participants were able to take down several record-sized government debt auctions without much trouble, suggesting investors had largely shrugged off the impact of a deluge of new bonds set to enter the market coming into the spring. However, the assumption that additional Treasury supply, to help support the economy through the pandemic, could be easily absorbed was challenged by the dismal showing for the 7-year Treasury note sale in February. Immediately after the auction, the 10-year note yield soared to 1.60% for the first time in a year, by some estimates. The spike in government bond yields spilled over into U.S. equities, triggering a steady slide for the Nasdaq CompositeCOMP,+3.69%,which ended in correction territory on Monday, but wastrading 4% higher Tuesdayas markets stabilized. Since last months ill-fated Treasury sale, long-term government bond yields have looked to carve out a new range, but at a much higher plateau than at the end of 2020.

Meanwhile, the 30-year bondyieldTMUBMUSD30Y,2.236%slipped 3.9 basis points to 2.265%. Bond prices move inversely to yields.
