Fixed Income.

With sticky inflation forcing the ECB to raise interest rates this month, monetary policy is driving the global financial narrative. Since monetary policy establishes the framework for all international borrowing and debt, this week we are focusing on Fixed Income to analyze how bonds and yields are impacting the broader economy and market.

The snapshot above is deliberately simple and shows the direction of euro-area government bond yields across different lengths of time, from two years out to thirty. A yield is just the return an investor earns for lending to a government by buying its bond. The arrows point upward because a central bank that is raising rates and signalling more hikes pushes yields up across the board.

But if we look past the shared upward direction, the yields on the different maturities are moving at different paces, and that is what brings us to the actual yield curve.

In finance, the yield curve is a chart that plots the interest rate of bonds with the same credit quality across different maturities. You may also hear the term tenor instead of maturities, which is the technical term for the length of time until a bond matures, spanning from short-term 2-year to long-term 30-year maturities.

In a perfect world, this curve slopes upward because time equals risk. If you lend money to a government for 30 years, a lot more can go wrong (inflation, recessions, world events) than if you lend it for just 2 years. So, in a healthy economy, investors demand a higher interest rate for long-term bonds to compensate for that risk.

This week, however, we are seeing the yield curve flattening. A curve “flattens” when the gap between short-term and long-term interest rates narrow. This happens when two different forces are pulling on opposite ends of the rope:

The Front End: Reacting to the ECB. Short-term yields are highly sensitive to immediate central bank moves. With the ECB just hiking rates and officials suggesting more hikes are to be expected, short-term yields are facing strong upward pressure.

The Back End: Worried about tomorrow. Long-term yields are driven by where investors think the economy is heading. This is where Chief Economist Philip Lane's warning that even though inflation is sticky, the risks to economic growth are skewed to the downside and business activity is already taking a hit.

When a central bank raises interest rates today, but the long-term outlook for growth looks weak, long-term yields fall behind short-term ones, flattening the curve. This reaction reflects a classic stagflation squeeze. Investors see the ECB lifting rates to fight inflation today, but they are deeply worried it will slow down economic growth tomorrow.

To understand the practical impact of these rising yields, imagine you bought a 2-year government bond a year ago at a fixed interest rate of 2%. Because the ECB has started raising interest rates again, newly issued 2-year bonds are now paying closer to 3%. So now your older bond pays less than the new ones, causing its present value to drop.

On paper, your safe investment lost value purely because a higher-rate environment emerged. This illustrates the inverse relationship between interest rates and bond prices where nothing changed with your underlying asset, but as market rates rose, its market value moved the other way.

However, this higher rate environment also creates an opportunity for new capital. Newly issued short-term bonds are paying more than they have in years, so the same market shift that reduced the value of old bonds makes the new ones a more attractive investment.
