Why do Negotiation dialog resets gold per turn to my current value?

[Legioner22]

Always when I type value of GPT in Negotiation dialog that is more than my current GPT, it automatically resets it. Why is this happening? Even if I will have negative income, I can take risks because I know that in near future my gold income may be increased. For me, it can be quite logical and the reasons for that limitation is not clear

You can't spend what you don't have. You can't go into negative GPT when making trades, it just makes sense since there is no World Bank to loan you the money.
Anyway there may be a way to get around this but it involves a lot of hassle: before starting the negotiation go to each of your city and move your citizens around to all the best gold tiles (even if you go into negative food), work all specialists in Markets, Banks, etc. This way you increase your GPT and if it is just enough to make the deal then it wasn't all for nothing. After the deal is done go back and assign each citizen to it's original tile and go into negative GPT.

Yes, move citizens on gold tiles is just workaround for that, i.e. we can trade with negative gpt, but only in such indirect way. Perhaps this is defect in game design

Why would it be a defect? If you could do that there would be potential for some really game-breaking exploits.
