The loan commitment made by X Inc is not a financial instrument, as it does not meet the definition of a financial instrument under IAS 32. It is merely an agreement to enter into a future transaction.
However, the change in the market interest rate will have an impact on the financial asset and liability that will arise when the loan is actually granted on 10 April 2018.
Effect on Financial Asset and Liability:
If X Inc has the practice of selling the loan asset resulting from the loan commitment shortly after the origination, it would recognize the loan asset and loan liability at fair value through profit or loss upon initial recognition. The difference between the fair value and the carrying amount would be recognized as a gain or loss in profit or loss.
