Who Will Be UK's Next Chancellor? Prime Minister's Resignation Ignites Economic Race

In July 2022, the resignation of then-UK Prime Minister Boris Johnson plunged the country into a period of significant political and economic uncertainty. The ensuing Conservative Party leadership contest to select a new leader also brought to the forefront questions about who would take charge of the UK's financial management as the next Chancellor of the Exchequer, and what economic roadmap they would pursue. Throughout this process, candidates' economic pledges and potential cabinet choices were closely monitored by markets and investors.

Two main candidates emerged in the leadership race: former Chancellor Rishi Sunak and then-Foreign Secretary Liz Truss. Sunak prioritized tackling inflation and fiscal discipline, while Truss distinguished herself with promises of extensive tax cuts and a focus on stimulating economic growth. Among Truss's economic advisors were free-market proponents like Kwasi Kwarteng, whom she would later appoint as Chancellor. These differing approaches fueled heated debates amidst the country's high inflation and cost of living crisis.

Markets reacted to this uncertainty from the outset of the leadership contest. Sterling (GBPUSD) experienced volatility due to political developments and the divergence in candidates' economic pledges. Analysts warned that UK government bond (Gilt) yields could rise if a candidate perceived as populist or prone to excessive spending were to win the leadership contest. Concerns, particularly regarding the financing of Truss's tax-cut-driven growth plan, dampened market appetite for risk and prompted investors to adopt a cautious stance.

The leadership race unfolded within the broader economic context of structural issues facing the UK economy in the post-Brexit era and a global energy crisis. Soaring energy prices had pushed inflation to record levels, compelling the Bank of England (BoE) to implement interest rate hikes. The strategy the new Chancellor would adopt in this challenging macroeconomic environment was of critical importance for the country's short- and medium-term economic outlook.

Upon Liz Truss's victory in the Conservative Party leadership election on September 5, 2022, and her subsequent assumption of the Prime Minister's office on September 6, she appointed Kwasi Kwarteng as Chancellor of the Exchequer, clarifying market expectations. Kwarteng's appointment was perceived as a clear signal that Truss's aggressive tax-cutting and growth-focused economic agenda would be implemented. However, this appointment and the accompanying policies would later lead to unprecedented volatility in UK financial markets. Markets continued to closely monitor the new administration's stance and actions regarding fiscal responsibility.
