Monzo, the British digital bank, has announced a secondary share sale, allowing employees to sell shares to existing investors, including Singapore's sovereign wealth fund GIC and StepStone Group, valuing the company at £4.5 billion ($5.9 billion). This share sale is designed to provide liquidity for employees and delays the need for a public offering while meeting investor demand. The bank, which achieved its first annual profit this year, has more than 10 million customers and is expanding in Europe and the United States. Monzo's valuation has increased from £4 billion in March, and the secondary sale comes ahead of potential capital gains tax increases in the UK. Despite speculation of an IPO, CEO TS Anil has not confirmed any immediate plans for a public listing. The rise in Monzo's valuation reflects a broader recovery in European fintech valuations post-pandemic.
