dont know much about bonds.

but ukraine is in the process of selling off whatever last valuables its got left

Ukraine to sell off assets including a hotel, a shopping centre and Europe's biggest titanium miner to raise funds for war with Russia

from what i could find, its pretty much pennies on the dollar.
that hotel is one of the most iconic buildings in kyiv on maidan. starting price - 25 million usd

europe's largest titanium miner - starting price 95 million usd..its a friggin bargain.
