Term structure describes how interest rates (or yields) for debt instruments differ based on their maturity date. Imagine you have a government that issues bonds; these bonds might have different maturities, such as 3 months, 1 year, 5 years, or 30 years. The term structure essentially plots the yields of these different bonds against their respective maturities. Instead of a single interest rate, it shows a curve, often called a yield curve, which depicts this relationship. A normal yield curve, for instance, slopes upward, indicating that longer-term bonds offer higher yields than shorter-term bonds. This is typically because investors demand more compensation for lending their money for a longer period, given the increased risk and uncertainty over time, such as inflation risk or the risk of interest rate changes. Conversely, an inverted yield curve, where short-term yields are higher than long-term yields, can signal market expectations of an economic downturn. A flat yield curve suggests that investors anticipate little change in interest rates in the future. Understanding the term structure is crucial because it reflects the market's collective expectation about future interest rates, inflation, and economic growth. It's not just about a single rate; it's about the entire spectrum of rates across different maturities. Various theories attempt to explain the shape of the yield curve, including the pure expectations theory, liquidity preference theory, and market segmentation theory, each offering different insights into investor behavior and market dynamics that influence term structure. For example, the liquidity preference theory suggests that investors prefer short-term bonds due to their greater liquidity, thus demanding higher yields for foregoing that liquidity with longer-term bonds. Analyzing the term structure helps market participants, from individual investors to large financial institutions, make informed decisions about borrowing, lending, and investment strategies.

An inverted yield curve, where short-term yields are higher than long-term yields, is often interpreted as a signal that the market anticipates an economic slowdown or recession. It suggests that investors expect interest rates to fall in the future.
Central banks influence the term structure primarily through their control over short-term interest rates. By raising or lowering these rates, they can shift the short end of the yield curve, which then impacts expectations and yields across the entire maturity spectrum.
