Minsky's theory was for private borrowers. We'll have to adapt it to sovereign borrowers. Here is the original idea:

Understanding Minsky's financial instability hypothesis
...
He identified three types of borrowers that contribute to the accumulation of insolvent debt: hedge borrowers, speculative borrowers, and Ponzi borrowers.
The "hedge borrower" can make debt payments (covering interest and principal) from current cash flows from investments. For the "speculative borrower", the cash flow from investments can service the debt, i.e., cover the interest due, but the borrower must regularly roll over, or re-borrow, the principal. The "Ponzi borrower" (named for Charles Ponzi, see also Ponzi scheme) borrows based on the belief that the appreciation of the value of the asset will be sufficient to refinance the debt but could not make sufficient payments on interest or principal with the cash flow from investments; only the appreciating asset value can keep the Ponzi borrower afloat. Because of the unlikelihood of most investments' capital gains being enough to pay interest and principal, much of this type of finance is fraudulent.
Below, I try to translate this into the language suitable for a sovereign borrower:
The "hedge borrower" can make debt payments (covering interest and principal) from current cash flows from
investments taxation. For the "speculative borrower", the cash flow from
investments taxation can service the debt
even in adverse financial and/or economic environments, i.e., cover the interest due, but the borrower must regularly roll over, or re-borrow, the principal. The "Ponzi borrower" borrows based on the belief that the
appreciation depreciation of the value of the
asset debt by inflation will be sufficient to refinance the debt but could not make sufficient payments on interest or principal with the cash flow from
investments taxation under current circumstances; only the
appreciating asset depreciating debt value can keep the Ponzi borrower afloat. Because of the unlikelihood of most
investments' capital gains benign inflationary environments being enough to pay interest and principal, much of this type of finance
is fraudulent must lead to hyper-inflation, or a catastrophic deflationary collapse of the Ponzi financing scheme.
