‘Easy money’ (quantitative easing and low nominal/negative real interest rates) has left a legacy of lots of zombie companies that should not still be in business, because they are not genuinely profitable. Cheap debt washed through the banking system keeps them afloat.

For the utilities, easy money has had a devastating impact, encouraging widespread financial engineering. Thames Water is the extreme example, but there are many others among the unlisted, privately owned, UK utilities. The result is a set of companies that are highly vulnerable to economic shocks being kept on life systems.

The impact is most obvious in the boardroom, where the focus is on servicing the debt, rather than on customers, future investment and R&D. As these are the elements that drive productivity growth, the long-term economic growth opportunities are seriously impaired.

Facing up to the consequences of zombie companies in the utilities sector means Special Administration, pulling the plug on the zombies, restructuring them, and selling them on to new owners. The debt holders will have to take a haircut. But what’s not to like about more productivity, more investment, better customer service, boards focused on their customers and the business? This has to be done now if we’re serious about turning around not only the utilities sector but the wider British economy. Instead of endlessly kicking the Thames Water can down the road, Ofwat should call in the Special Administrator now. The costs of not doing so are serious.
