The domino effect: what do rising interest rates mean?

The Bank of England has announced a generally expected rise of the benchmark interest rate to 1%, just 0.25% higher than the previously prevalent rate, putting interest rates at the highest level since the time of the Global Finance Crisis in 2009.

Western countries, including the UK, are used to "cheap" capital, primarily debt. The rise in interest rates means that, along with the inflation-led slowdown in growth, the inexpensive debt will have to be rolled over to more expensive debt in an environment of economic slowdown or contraction. This puts a significant proportion of companies at risk of not being able to pay their debts.

The inability of a few companies to repay debt, and the downsizing that it entails, can have a domino effect on other businesses, which have been otherwise less levered and in better financial health. For instance, if a client firm becomes insolvent and stops buying services from a financially healthy vendor, then the vendor may have to downsize so that it eliminates unnecessary operating capacity. This process can happen across the economy, leading to lower employment. This leads to lower consumption, and subsequently, less business activity: the vicious circle of a recession can accelerate fast, and any state support will come at a steep cost for future generations.

The UK, EU, and North America have shown great resilience in the last couple tumultuous years. It will only remain to see whether the Bank of England, and other central banks, can achieve the broadly coveted "soft landing".
