Limit of government debts

2017/10/30. Limit of government debts

I am thinking about current Japanese government debts, how much the limit is...

If tax income is house income, all government assets is assets for house, how much does the current Japanese government rent the money? 

I thought that (3-5 times to tax income + assets) is limit. 

Tax income per year=50@2012

Government assets =647@2012

Government debts =1020 @2012

Already limit is over, so my thought is doubtful. What’s wrong?

The reason of 3-5 times to tax income is the limit of buying real estate.

But this reason is something wrong.

Are there any other signals for deciding debts limit?

Bankruptcy signals in Japan is being able to return debts for 3 years or not.

And the banking rates is 15%.

So if banking rates is 1-2%, the limit will be higher. 20-40 times to tax incomes may be right for decisions the limit of government debts.

If (20-40 times to tax income + assets) is limit, the limit of government debts will be 1600 - 2600. 

Government debts @ 2017 = 1300. (+200 took 6 years.) (+100 = 3 years)

So if the limit is 1600, the bankruptcy year will be approximately in 2023.

#But there may be hidden debts by local government.
