This is 100% correct. In a fiat currency system with no gold backing, the equilibrating mechanism is no longer interest rates per se, but the level of the free-floating currency relative to other currencies (esp the $). In such a situation, the relevance as far as the UK is concerned is the extent of foreign (i.e. non-sterling) borrowings on the debt. In the UK's case today, it is a non-factor. Virtually all of the borrowing is being done in sterling, so there is no question as to whether the UK government can continue to service the debt because, as the sole issuer of the pound, it can always service the debt. I also suspect that at some point, sterling becomes sufficiently low relative to other currencies, and that may well attract additional inflows from institutions/individuals, who view sterling based assets as "cheap".

That the UK government is highly unlikely to face a 1970s style currency crisis in which the IMF might have to be called in DOES NOT, however, vindicate the strategy adopted by the Truss Administration. The new policies announced last week by Kwasi Kwarteng offer the worst of all possible worlds: they do nothing to address the gaps in the supply chains that did so much to create the inflation in the first place. To the extent that this package delivers expansionary fiscal stimulus, it is directed to the wrong people. The benefits largely accrue to the cohort with the highest savings propensities, so it's terribly inefficient and will also likely exacerbate prevailing inequalities (and the UK is one of the most unequal economies in the G7, in fact it might be THE most unequal and this fiscal plan will make it worse). In fact, as the Shadow Chancellor, Rachel Reeves, noted the other day in the FT, "research by the IMF has shown that higher income inequality is associated with lower and more fragile growth. It is obvious why. Concentrating income among fewer people — those least likely to spend it and drive the economy forwards — undermines workers’ health and education, the crucial components of a productive workforce."

Likewise, as Stephanie pointed out in her previous piece, there is a substantial body of economic work illustrating that "trickle down economics" is fiscally inefficient in terms of delivering decent bang for the buck to foster greater economic growth. So to the extent that the tax cuts induce any kind of spending response, we'll get more demand that will likely go to the wrong areas (e.g. prime London property), as opposed to funds that will generate more equitable growth and prosperity.

Sadly, the British government remains very deliberately wedded to the myth that it needs to run to the nearest lender every time the stationery cupboard gets low on pencils. (The feudal aristocracy of the private economy would have it no other way.)
