This CPI + % wheeze is a dangerous tool which threatens severe impact now that government has forced its citizens to rely upon it for communication. Already inflation is running around 10% and the Bank of England seems no more likely to tackle it than it was a year ago when it should have acted. It's more and more likely the politicians are leaning on the bankers, but in so doing they are postponing an ever bigger crunch.
The financial Press are warning that international investors are concerned by the size of UK debt and may no longer consider Govt bonds as a secure investment = except for higher interest on their investments. Stand by for even higher interest rates = higher inflation = you can guess the rest. This from someone who remembers the mortgage rate hitting 15% some 43 years ago.
The alternative is data caps or metered, pay for what you use. Pretty dangerous too.
From what I've read the financial press / investors largely think our currency and in turn economy is suspect because of our stubborn refusal as a nation to attribute any of our issues to the 'B' word or to try and adopt pragmatic solutions to facilitate trade in goods and services.
Can't expect the markets to take a nation seriously when its reflexive response to trade issues is distraction, excuses and pointing to epic trade wins worth at most 0.1% of GDP, where we bent over to take it because the government were desperate for press release material, rather than actually doing anything constructive.
We have years of this left as our economy at best transitions and at worst stagflates so may as well get used to it. Sterling as a reserve currency is pretty much over, it's what the people voted for apparently, and with that comes increased volatility.
