You don't need "monads" (in plural) since GHC provides a runtime where threads are not 1:1 OS threads but rather are managed at the user level, similar to what you have in Go. You can implement async/await as a library though [1]

What do you mean with "in plural"?

In the sense that you only need to work with the standard IO monad to get the benefits of the runtime.
