Duration explained simply

🧭 Background & Context Duration measures the average time capital is tied up in a bond and indicates how strongly its price reacts to interest rate changes. Simply put: If interest rates rise by 1 percent, the price of a bond with a duration of 5 years falls by about 5 percent – and vice versa. For private investors, this is the key lever for understanding interest rate risk in their own portfolio, because the longer the duration, the more volatile the price movement. In an economic context, this means: In phases of rising interest rates (as recently), long-dated bonds or bond funds with high duration suffer particularly badly, while short maturities are less affected. Conversely, long durations benefit disproportionately from falling interest rates, as prices then rise more sharply. Private investors should therefore use duration as a risk indicator to align their bond positions with their own investment horizon and interest rate expectations – not as a guarantee, but as a compass for volatility intensity. Those who ignore duration can quickly experience unexpected losses at interest rate turning points, even if the bond is held until maturity. 🔍 How It Works in Detail The „⏳ Duration“ function is a simple timer that shows you how long something takes. You start it, and it counts up the elapsed seconds, minutes, or hours – like a stopwatch. The practical thing: You can also run it backwards, i.e., set a target time, and it counts down until the time is up. It works on the principle of „start minus end“: With the stopwatch, you measure the time between start and stop; with the countdown, the time between now and a set point in time. The display updates in real time without you having to do anything. All you need to remember is: Start, let it run, stop – or simply specify a duration and wait until it has elapsed. There’s nothing more to it. 💡 Opportunities & Use Cases For private inves …
