Borrowing money allows you to afford today what, before, you might have had to have waited decades to be able to afford. And, in theory, if you’re borrowing in order to create something that improves your production levels then you’re also gaining a stronger ability to pay off that loan.
If a country defaults on its loans, my expectation would be that the lenders would be able to go to courts in various nations and request to be able to claim assets owned by the foreign government and to be able to seize money if it is transferred through that nation.
While the Russian government might be able to expect that it will lose some buildings and limos that it has parked around the world, probably the threat of money transfers getting waylaid would be the larger issue, along this front. They’ll have to use more circuitous means of sending money abroad - and likely with higher fees from the intermediaries.
But, from a functional standpoint, they already received the loan money. It’s really the banks who are losing out on this one. So the bigger issue is that they won’t be able to borrow money, any more. Russia can issue bonds to its own citizens and maybe still find some banks willing to lend them money, in China, Iran, etc. but it’s going to have a much smaller pool of money to work with in the future.
If they ever get back into the world’s graces again, they might be obligated to pay some fines before they will be allowed to borrow again and they might be forced to borrow at higher interest rates than before. It’s going to be a slog to get back into good standing. (Though, this is a future problem that may be decades or centuries from mattering in any practical way.)
That said, money is fundamentally a human construct. Today, Russia’s people are paid to do work and, if the government wants them to work for the government, they might have to borrow money to be able to afford all the new workers. But there’s nothing to say that Russia can’t just hire a small gang of mercenaries to roam around, forcing people to work at gunpoint, giving all their material possessions to the government. If the Russian government wants to build a space ship that can take mankind to Mars, it doesn’t necessarily need the money to do it if it can compel a sufficiently large number of people to do all the work.
In a free market, losing the ability to borrow reduces your ability to get work done. In a frighteningly real world, however, your ability to get work done is simply limited by how many people you control, how well you can keep them motivated, and how good you are at identifying capable individuals. A smaller total workforce, though, will always mean that you have fewer extra-talented individuals available. In a global economy, borrowing can allow you to finance projects from the whole world’s supply of top talent.
Their problem will be less that they can’t borrow and more that they’re isolated and dependent on the individuals physically in Russia.
Defaulting is largely an issue with how Russia interfaces with the rest of the world. If it’s not going to be interfacing with us, anyways, then it doesn’t really matter too much. (Again, until they decide to re-integrate.)
Within the nation, the total quantity of rubles effectively equals the total number of assets available to the nation + the amount of labor potential that they have. If you print more rubles, that largely stays the same (after things settle out) and if you collect and burn rubles, that largely stays the same (ditto). Money is just a way for people to trade services and assets, and they use the ratio of non-monetary wealth + rubles in their possession to those in their trade partners’ possession to determine what the value is of a ruble.
When you remove foreign trade partners from the equation, the price of a ruble comes to equate to the capabilities of the Russian economy as viewed only from within itself. When you have foreign trade partners, the value of a ruble is tempered by external trade partners and their monetary + non-monetary wealth.
The Russian market is going to have to recalibrate while it’s unclear exactly what capabilities their nation has. That will be disruptive and damaging to people in the short term, but they’ll make due in part by swapping non-monetary assets, whose relative value compared to one-another is more certain.
None of that has anything to do with their external loans. The craziness comes from becoming an interconnected nation to becoming an isolated nation. Defaulting on the loans has no internal effect since, as said, they’ve already received the money and it’s now just part of the pool of rubles in circulation.
