U.S. Treasuries (Treasury)
Bonds the U.S. government issues to borrow money — regarded as the world's safest asset, and used as a reference point for interest rates and stock markets.
By maturity, they are split into short-term (T-Bill, 1 year or less), intermediate (T-Note, 2–10 years), and long-term (T-Bond, 20–30 years).
When Treasury yields rise, the "interest you can earn safely" grows, creating pressure that reduces the relative appeal of stocks as risk assets (especially on growth-stock valuations).
In plain terms
A Treasury is an IOU the U.S. government issues, saying "lend me money and I'll pay it back with interest." Since there is almost no worry about default, it is called "the safest asset in the world."
For Treasuries, price and yield move in opposite directions like a seesaw. When buyers pile in, the price rises, and in exchange the interest rate (yield) you newly receive falls.
What it tells you
The 10-year Treasury yield in particular is the market's "benchmark for long-term rates," so it affects a wide range of things from mortgages to stock valuations.
When a crisis hits, investors rush into safe Treasuries (flight to safety). So whether money is flowing into or out of Treasuries is sometimes read as a sign of market anxiety or relief.
Formula
By maturity, they are split into short-term (T-Bill, 1 year or less), intermediate (T-Note, 2–10 years), and long-term (T-Bond, 20–30 years). Treasury prices and rates (yields) move in opposite directions (price ↑ = yield ↓).
What high or low means
When Treasury yields rise, the "interest you can earn safely" grows, creating pressure that reduces the relative appeal of stocks as risk assets (especially on growth-stock valuations).
When Treasury yields fall, the opposite tends to happen: the environment becomes more favorable to risk assets such as stocks.
"Safe" means the government will not skip repayment — it does not mean the price stays fixed. When rates rise, the price of existing Treasuries falls and losses can occur.
Treasury yields move with the macro environment (inflation, Fed policy), and affect individual companies with a time lag.
Even within "Treasuries," the character and the risks differ by maturity (2-year, 10-year, 30-year).
The US Treasury yield is treated as "the return you get while taking no risk at all," so it becomes the starting point for the price of almost every asset in the world. Stocks and real estate are riskier than Treasuries, so they are expected to earn at least "the Treasury yield plus compensation for risk."
So when the 10-year US Treasury yield jumped from the 1% range to the 4% range in 2022, tech stocks—valued at high multiples on profits pulled in from the distant future—were pressed down especially hard. When the required return (discount rate) rises, the same company is valued lower. It shows that Treasuries are not merely a "safe asset" but the benchmark that lines up the price of every asset.
