Why do mortgage-backed securities have negative convexity?
Most mortgage-backed securities (MBS) will have negative convexity because their yield is typically higher than traditional bonds. As a result, it would take a significant rise in yields to make an existing holder of an MBS have a lower yield, or less attractive, than the current market.
Why do bond yields rise and fall?
A bond’s yield is based on the bond’s coupon payments divided by its market price; as bond prices increase, bond yields fall. Falling interest interest rates make bond prices rise and bond yields fall. Conversely, rising interest rates cause bond prices to fall, and bond yields to rise.
Is high convexity good or bad?
Convexity in bonds is a way to measure the bond price’s sensitivity to changes in interest rates. Bonds with higher convexity are generally considered better investments in markets where interest rates are expected to rise, and lower convexity is better suited for when rates are likely to remain unchanged or fall.
What causes negative convexity?
Negative convexity occurs when a bond’s duration increases in conjunction with an increase in yield. The bond price will drop as the yield grows. When interest rates fall, bond prices rise; however, a bond with negative convexity diminishes in value as interest rates decline.
How do you increase convexity?
To increase convexity, the more distributed future cash flows of a barbell will have higher convexity, but lower yield. To decrease convexity, the more concentrated future cash flows of a bullet will have lower convexity, but higher yield.
How do you hedge negative convexity?
Negative convexity is a feature often found in callable bonds and mortgage backed securities.

- purchasing a payers swaptions.
What does negative convexity look like?
What Is Negative Convexity? Negative convexity exists when the shape of a bond’s yield curve is concave. A bond’s convexity is the rate of change of its duration, and it is measured as the second derivative of the bond’s price with respect to its yield.
What is a high convexity?
Pointedly: a high convexity bond is more sensitive to changes in interest rates and should consequently witness larger fluctuations in price when interest rates move. The opposite is true of low convexity bonds, whose prices don’t fluctuate as much when interest rates change.
How do you interpret convexity?
To interpret a convexity number, think of it as being the percent change in modified duration from a 1% change in yield. To estimate what the effect of including convexity in a price change calculation for a 1% change in yield, multiply the convexity by 1%^2=1%*1%.
What is a convexity hedge?
The rise in Treasury yields creates the need for investors who hold mortgage-backed securities (MBS) to reduce the risks on the loans they manage and limit the negative effects of slower loan prepayments when interest rates climb, a move known as “convexity hedging”.
Do investors like convexity?
Convexity is an important tool used by investment professionals to show the impact that changes in yield have on the duration of a bond. It’s an especially important consideration during times of volatility on markets.

What does a convex look like?
A convex shape is the opposite of a concave shape. It curves outward, and its middle is thicker than its edges. If you take a football or a rugby ball and place it as if you’re about to kick it, you’ll see that it has a convex shape—its ends are pointy, and it has a thick middle.
What is convexity and concavity?
A function of a single variable is concave if every line segment joining two points on its graph does not lie above the graph at any point. Symmetrically, a function of a single variable is convex if every line segment joining two points on its graph does not lie below the graph at any point.
