Oil, gilts and a hot CPI print push yields to a 19-year high
UK 10-year gilt yields breached levels last seen before the financial crisis after oil prices jumped and inflation expectations rose. US and Indian equities fell too, though a Friday rebound softened the week's losses.
The week in figures
Each figure as at its own date · sources in the issue
Yields are repricing a shock, not a new regime
The week's story is a chain, not a coincidence. Oil went up sharply after fresh US-Iran strikes in the Persian Gulf, gilt and Treasury yields went up in response, and equities fell in step until Friday, when oil eased and stocks recovered some of the ground. None of that requires a change of view about growth or inflation over the next few years. It requires only a view about what a supply shock to energy does to prices in the next few months, and markets have been quick to answer that question with certainty they do not really have.
