The Deloitte Consumer Tracker Q4 2017 indicates that consumer confidence in the UK remains flat at -7%, marking the first quarter without a decline since the survey's inception. Despite economic challenges, there are signs of consumer optimism, particularly regarding disposable income and debt levels, with an expected rise in real-wage growth for 2018. Retail sales were disappointing in December, attributed to rising inflation and low wage growth, but consumer spending intentions for the upcoming quarter show increased confidence compared to previous years.
