The UK's economic growth prospects could be constrained by a sustained reduction in net migration, with potentially far-reaching consequences for tax revenues and public services. According to analysis from the Office for Budget Responsibility (OBR), a reduction of 100,000 workers per year over the next five years could see a cumulative decrease of £23 billion in national income by 2030.
This finding emerges as the government implements stricter immigration policies aimed at significantly cutting net migration, which reached a record high of 745,000 in 2022. The OBR's role is to provide independent forecasts for the UK economy and public finances, informing the government's fiscal decisions and warning about the potential trade-offs between policy objectives.
The OBR's analysis typically incorporates assumptions about future population growth and labour force participation, with migration being a crucial component of both. A reduction in the inflow of workers could impact sectors reliant on foreign labour, potentially leading to skill shortages and reduced productivity growth. This could, in turn, affect the overall size of the economy and the tax revenues available to fund public services.
Economic growth is driven by factors such as productivity, investment, and the size of the labour force. While some argue that high migration can put pressure on public services and infrastructure, economists often point to its role in boosting the working-age population, filling labour market gaps, and contributing to innovation and dynamism. The OBR's warning underscores the complexity of balancing social and economic objectives in immigration policy.
The government's stated aim is to ensure that migration benefits the UK economy while addressing concerns about the sustainability of current levels. However, the OBR's latest assessment suggests that achieving significantly lower net migration without a corresponding impact on economic potential will be a challenge. The long-term implications for the UK's economic competitiveness and its ability to fund an ageing population will be closely scrutinised.
Opposition parties have frequently criticised the government's approach to immigration, arguing that it fails to address underlying labour market issues and could harm key sectors. They often highlight the reliance of the NHS and social care on foreign-born staff, as well as the contributions of international students to the UK economy. The OBR's findings are likely to fuel further debate on these issues.
