What you need to know about implied repo rate.
With the implied repo rate, the bond an investor buys is held until it is delivered into the futures or forward contract and the loan is repaid. The term derives from the reverse repo market, which functions similarly to a traditional interest rate and is also sometimes referred to as Return to Hedged Portfolio (RHP). The implied repo rate is calculated as the annualised rate of return for the transactions including purchasing, sale and delivery, with the calculation taking into account all the cash flows associated with the security.
