Household spending power in Britain experienced a decline in August as rising mortgage rates and increasing fuel and energy costs exerted pressure on family budgets. Data from the latest Asda income tracker, which monitors the amount households have available after taxes and essential expenses, showed that spending power growth eased to 3.4 percent in August from 3.7 percent in July. The drop was particularly pronounced among low-income households, which are now facing an average weekly shortfall of £75 between their earnings and essential expenditures.

Across all income groups, essential costs increased by 3.9 percent in August, slightly outpacing income growth, which stood at 3.8 percent. On average, families have around £260 per week remaining after covering bills and essential costs. However, discretionary income—the amount available for non-essential spending—fell by £1.41, or 0.5 percent, compared to the previous month.

Economist Pushpin Singh of the Centre for Economics and Business Research (Cebr), the organization that compiles the income tracker, highlighted that wage growth has been surpassed by a significant acceleration in inflation. Singh emphasized that inflation continues to pose the main threat to household spending power, with ongoing increases in essential costs and potential future interest rate hikes likely to further squeeze discretionary incomes.

Last week, the Bank of England decided to maintain interest rates at their current level but signaled that rates may rise if the ongoing conflict involving Iran persists. This outlook adds to concerns about the financial strain facing British households, especially those on lower incomes.

The combination of higher living costs and borrowing expenses underscores ongoing challenges for consumers navigating a complex economic environment influenced by geopolitical risks and domestic inflationary pressures.
