Government Bonds Coupon Pricing

Hey everyone in hot copper world.

I have what I thought would be a simple enough question I’m looking to get some assistance on.

I cant find any literature that will explain to me what determines the coupon rate on government bonds.

I appreciate that they are traditionally higher as interest rates go higher but I cant find information that explains how or why.

Is anyone able to point me in the right direction either with a book or a website that might give me a better understanding please?


Appreciate the help in advance!
