Like just about any other asset, Treasurys are affected by supply and demand. Investors often turn to these government-backed securities during times of economic uncertainty. Higher demand pushes prices higher, but it also means Treasury yields are lower because bond prices and yields are inversely related.
Imagine a Treasury with a face value of $1,000 and a yield of 4%, meaning it pays $40 in annual interest. Due to increasing demand, the price rises to $1,050. Since the Treasury still pays $40 per year, the yield has decreased to 3.8%. On the other hand, if the price fell to $950, the yield would go up to 4.2%.
How investors can use Treasury yields
Treasury yields are important for investors who want a safe place to put their cash. If you have money you'd like to grow with minimal risk, Treasurys are one of the best options since they're backed by the full faith and credit of the U.S. government. You can use yields to calculate how much interest you'll earn and to decide how long of a Treasury to get.
