This chapter examines the contribution of recognized activities that make the UK economy, such as the progress in research, pharmaceuticals, technology, software, and innovation that can be traced back to the intellectual powerhouses of UK's institutions of higher learning. It recounts the UK's love–hate relationship with the City of London, wherein the banks are still blamed for the financial crisis of 2007–2009 and the subsequent stagnation and fall in incomes. It also cites finance as the highest UK earner of overseas income and is a magnet for international institutions. The chapter describes London as the biggest financial centre outside New York and has attracted even greater numbers of skilled financial traders since the EU referendum result of 2016. It explains how the UK financial sector accommodated trading, provided credit, and raised new capital for troubled firms and those seeking post-Covid-19 opportunities.
