Sky Claw bonds

Describe a common form of currency in your world. Who issues it and what is its value?
The kingdom and mercenary company known as The Sky Claws issues a %7 bond which matures in five years, offered by the kingdom's debtor's guild, with the promise to beat the average inflation rate by about 4% - 7%. The coinage received in exchange for the note is then conservatively invested back into the bank which charges higher fees and offers more flexible investment instruments and the sky guild which is in charge of the manufacture and distribution of airships.
