  A recession is defined as two consecutive quarters of negative real GDP growth. An increase in the interest rate by the central bank, such as the US Federal Reserve, is a contractionary monetary policy tool aimed at reducing aggregate demand (AD) to control inflation. While this action significantly increases the risk of a recession, it does not make it inevitable.

  On one hand, an increase in the interest rate can be seen as making a recession inevitable. The primary transmission mechanism is through its effect on consumption (C) and investment (I), the two largest private sector components of AD. A higher interest rate increases the cost of borrowing for consumers, discouraging spending on durable goods financed by credit, such as cars and houses. It also increases the rate on variable-rate mortgages, reducing households' disposable income. Simultaneously, it makes saving more attractive, further dampening consumption. For firms, a higher interest rate raises the cost of financing investment projects, making fewer projects profitable and thus leading to a fall in investment. This combined fall in C and I causes the AD curve to shift to the left, leading to a fall in real GDP and an increase in demand-deficient unemployment. If this contraction is sufficiently large and sustained, a recession will occur.

  On the other hand, a recession is not an inevitable outcome. The effectiveness of interest rate hikes depends on the interest elasticity of demand for consumption and investment. If consumer and business confidence are very high (strong 'animal spirits'), or if households have significant savings, they may continue to spend and invest despite higher borrowing costs, meaning C and I are interest inelastic. In this case, the leftward shift in AD would be minimal. Furthermore, other components of AD could offset the fall in C and I. For example, the government could be engaging in expansionary fiscal policy, increasing government spending (G). Alternatively, strong global economic growth could boost demand for US exports (X). If these other factors are strong enough, they can cushion the economy and prevent real GDP from falling for two consecutive quarters.

  In evaluation, whether a recession occurs depends on the context and the magnitude of the policy change. It is not inevitable, but the probability is high. The key factor is whether the central bank can achieve a 'soft landing' – reducing inflation without causing a significant economic downturn. This depends on the magnitude and speed of the interest rate increases; small, gradual rises are less likely to shock the economy into recession than large, rapid ones. It also depends on the initial state of the economy; an economy starting from a position of very low unemployment and high growth has more capacity to absorb the rate hikes than one that is already fragile.

  In conclusion, an increase in the interest rate does not make a recession in the US inevitable. While it is a powerful tool that directly contracts aggregate demand, its ultimate effect is contingent on behavioural responses (elasticity), the strength of other economic variables, and the skill of policymakers in calibrating the policy. Therefore, a recession becomes a strong possibility, but not a certainty.

  How the marks are awarded

  • AN1 — The second paragraph explains how higher interest rates increase the cost of borrowing, reducing consumption (C) and investment (I), which shifts aggregate demand left and leads to lower real GDP, potentially causing a recession.
  • AN2 — The third paragraph explains why a recession might not happen, referencing the concept of interest inelasticity of demand and the potential for other AD components (like G or X) to offset the fall in C and I.
  • EV1 — The fourth paragraph provides evaluation by weighing the factors, considering the magnitude of the rate hikes, the initial state of the economy, and the concept of a 'soft landing' versus a recession.
  • EV2 — The final sentence provides a clear and justified conclusion, stating that a recession is not inevitable because the outcome is contingent on various factors, making it a possibility rather than a certainty.

  Common mistakes

  • Providing a one-sided argument, only explaining why a recession would happen and failing to discuss counter-arguments, thereby losing all AN2 and EV marks.
  • Failing to define 'recession' at the start, which shows a lack of precision and command of key terminology.
  • Stating that the impact of interest rates is certain, rather than discussing it in terms of probability and dependence on other factors like elasticity and confidence.
  • Writing a weak or undeveloped evaluation, such as simply saying 'it depends' without explaining what it depends on (e.g., the size of the rate increase, consumer confidence, other components of AD).

  Examiner tip: For 'assess' questions, always build a balanced argument by explaining reasons 'for' and 'against' before making a final, justified judgement that weighs up these competing factors.
