Inflation surged significantly post-2021, prompting the Bank of England to raise the official Bank Rate from historic lows of 0.1% up to 5.25%. This dramatic monetary tightening cycle raised fears of a sharp contraction in capital expenditure across the UK economy. Traditional economic theory suggests that higher interest rates increase the opportunity cost of using retained earnings and raise the cost of debt finance, thereby reducing the net present value of investment projects.
However, UK business investment showed surprising resilience in certain sectors during 2023. Many large corporations had accumulated significant cash reserves during the preceding years and did not need to rely heavily on bank loans. For these cash-rich firms, higher interest rates meant higher returns on their cash holdings, though the rising cost of capital still influenced their investment hurdle rates.
Additionally, a major driver of investment was fiscal policy. The UK government introduced a generous 'Full Expensing' capital allowance system, allowing companies to deduct 100% of their spending on qualifying plant and machinery from their taxable profits immediately. This tax relief significantly lowered the effective cost of investment, offsetting some of the negative pressures from high bank lending rates.
Furthermore, long-term structural shifts, such as the transition to net-zero and the rapid adoption of artificial intelligence (AI), forced many firms to invest regardless of short-term financing costs. On the other hand, small and medium-sized enterprises (SMEs) were disproportionately affected by the credit squeeze, as they rely more on variable-rate bank debt and lack the massive cash cushions of multinationals. Business confidence (Keynesian 'animal spirits') remained fragile, with many firms citing uncertainty over future consumer demand rather than high interest rates as the primary barrier to expansion.
