Inverse Interest Rate Risk

PreviousInterest Rate RiskNextAMM Curve Comparison

Last updated 2 years ago

Can you get more than the promised yields on @notionalfinance ?

YES!!

Sometimes, the interest rates can change in your favor and make you more money. ๐Ÿ’ฐ

Let me explain how. ๐Ÿ‘‡

---

When you enter a trade, you lock in a certain interest rate on your fCash. This is the rate that determines how much interest you will earn on your fCash over time. ๐Ÿ“ˆ

But if the interest rate goes down while you are in the trade, your fCash becomes more valuable. ๐Ÿš€

---

Hereโ€™s an example to illustrate this point. ๐Ÿ“‰

Suppose you enter a trade with 100 Cash and 100 fCash at a 5% interest rate. You hold your position for 3 months and then exit at a 4% interest rate.

How much do you think you will make or lose? ๐Ÿค”

---

If you do the math, you will find out that you will make 0.67 Cash in this trade. Thatโ€™s a positive APY of 6.69%.

Why? Because your fCash is now worth 100.67 Cash, but you only have to pay back 100 Cash.

Thatโ€™s a good deal, isnโ€™t it? ๐Ÿ™Œ

---

But what if the interest rate goes up instead of down? Does that mean you will lose money? ๐Ÿคทโ€โ™‚๏ธ

Not necessarily. ๐Ÿ˜Š

Remember, we talked about how the exchange rate between fCash and Cash approaches 1:1 as the maturity date gets closer? ๐Ÿ“…

Well, that means that if you hold your position until maturity, you will get the promised APY regardless of the interest rate changes. ๐Ÿ”ฅ

---

Hereโ€™s another example to show you how this works. ๐Ÿ“ˆ

Suppose you enter a trade with 100 Cash and 100 fCash at 5% interest rate. You hold your position until maturity and then exit at 7% interest rate.

How much do you think you will make or lose? ๐Ÿค”

---

If you do the math again, you will find out that you will make 0 Cash in this trade. Thatโ€™s an APY of 5% (including fees).

Nice! ๐Ÿ˜Ž

Why?

Because your fCash is now worth exactly 100 Cash, you also have to pay back 100 Cash.

Thatโ€™s exactly what you signed up for, isnโ€™t it? ๐Ÿ‘

---

Thatโ€™s it for this thread. I hope you learned something new today about interest rate risk and how to benefit from it. ๐Ÿ’ฏ
