Will Russia upset the sectoral balances?

Posted on

This is one for the geeks, I must admit.

As those who understand sectoral balance accounting know, these balances must by definition add up to zero. That is because in accounting terms every debit must have a credit, which is a reality matched exactly in the real world by the fact that for every lender there must be an equal and opposite borrower.

This is the chart for the sectoral balances for the UK from the most recent budget:

The importance of this chart is that it shows who is borrowing, and who is saving within the UK economy, split between the four major subgroups that exist within it i.e. the government, households, businesses and the overseas sector.

I normally recommended that any forecasts produced by the government with regard to where the sectoral balances are going be ignored. There is good reason for doing so: these forecasts are usually works of fantasy designed to suggest that the government will eliminate its deficit, which is a goal that it rarely succeeds in achieving. That is what this chart, predictably shows.

However, there is something more important to look at in this case, and that is the green line, which is the contribution made by the overseas sector. These funds are those provided by individuals, companies and governments from outside the UK who save in this country. Part of that saving is reflected in investment in bank accounts. Some might be in shares, but the largest part may well be the reserves of foreign governments held in the form of UK government bonds, which do of course represent loans to the government, in effect (and yes, I know all the modern monetary theory arguments).
The very obvious question to ask at present is what might the impact of the conflict with Russia have on these balances? It is thought that Russia had  the fourth largest overseas reserves balances in the world prior to this conflict beginning. It is, of course, now known that many of these balances have been frozen, including those in the UK. Assuming, however, that at some time this conflict will come to an end and that those reserves will be released, which would reflect some sort of return to welcome order, then how is Russia likely to react?
My suggestion is that they are not going to be too keen to hold these reserves  in any country that froze their assets, including the UK. It is much more likely that they will either move them to China or, alternatively, they will hold gold. Whatever their choice, I think that the relatively stable flat green line shown on the chart until 2026 for overseas balances might, in this case, be decidedly optimistic.
If that is the case then the UK government might find it harder to balance its books. Readers of this blog will know that I consider that to be a matter of some indifference: there is absolutely no necessary virtue, and often some degree of peril, in pursuing this goal. However, that does not prevent the Treasury thinking otherwise, and if they think that Russian reaction might make this goal harder to achieve then the pressure for austerity coming from that source will only increase.
If that happens we will suffer, yet again, for their stupidity.
