It is an exchange between two people. What does the second person mean exactly?
- I don't suppose that we have.
- I don't suppose that we don't have.
Or both are possible and it depends on the context?

Think about the verb phrase "have enough money". The first person is saying "we don't have enough money" and the second person is saying "I don't suppose we do have enough money". The topic they are discussing is the act of having enough money.
This is confusing because here "I suppose so" and "I don't suppose so" mean the same thing. A different construction would be used to negate it, as "I [don't] suppose so" in response to a negative always affirms the negative.
