Interest-Rate Cuts Rely on Inconvenient Truths About Inflation

The tricky last yards of closing in on — and then maintaining — the hallowed 2% inflation target that all the major central banks adhere to requires a change of tactics. Over the past two years, a mantra of economic data-dependency has been drummed into us, keeping interest rates higher for longer. This ethos is in danger of becoming, well, a bit inconvenient as the mood swings toward rate cuts.

July US and UK consumer price inflation numbers this week are both expected to tick up. That risks muddling carefully crafted central bank messaging that restrictive monetary policy is coming to an end. The Federal Reserve is widely expected next month to follow the European Central Bank and Bank of England, which have already taken the first steps in lowering rates.
