Former Chancellor Kwasi Kwarteng has warned that the government may be forced to introduce further tax rises to fund additional energy subsidies, as escalating oil and gas prices put fresh pressure on public finances.


His comments come amid heightened market volatility resulting from the ongoing conflict involving Iran, which has driven up global energy prices and pushed UK government borrowing costs sharply higher.


The situation echoes financial turmoil seen during Kwarteng’s term in 2022, raising concerns that similar economic challenges could confront the current government without prompt and decisive fiscal measures.

Former Chancellor raises concerns

Kwasi Kwarteng, who served as Chancellor of the Exchequer during 2022, stated that the government risks a financial crisis if it increases borrowing to fund further energy support schemes in response to rising prices.


He remarked that tax increases could become unavoidable, possibly as soon as November, should policymakers offer more financial relief to households facing surging utility bills.


Kwarteng highlighted parallels with the 2022 market disruption, which was fuelled by geopolitical tensions following the Russian invasion of Ukraine.


He noted, “I think the spike then in terms of gas prices was much greater than today but there’ll be similar pressures for the government in terms of helping people with bills.”


Kwarteng emphasised that any form of government support would need to be evaluated by the Office for Budget Responsibility (OBR), with potential implications for the national tax burden.

Volatile markets recall 2022 crisis

Recent days have witnessed a sharp rise in government bond yields, with the 10-year gilt yield climbing by up to 14 basis points. This surge reflects investor concern that sustained energy price rises could reignite inflationary pressures, thereby increasing funding costs for the government and intensifying scrutiny of its fiscal response.


Kwarteng’s experience with the 2022 ‘mini-budget’ remains prominent in the debate. That event, marked by a package of unfunded tax cuts and emergency energy subsidies, triggered severe market instability and ultimately precipitated a change in government leadership. Market participants are reportedly monitoring the situation closely, wary of any move that could undermine fiscal discipline.

Treasury approaches and OBR scrutiny

The Treasury is under increasing pressure to respond to escalating calls for financial assistance from consumers and industry alike. Kwarteng suggested that officials will likely resist repeated appeals for generous subsidies.


He explained, “Any subsidy that you come up with, you’ll have to pay in higher taxation towards the end of the year. I’ve been here before.” The OBR, as the government’s independent fiscal watchdog, is responsible for scrutinising the financial impact of policy interventions.


Any significant spending on energy support is likely to influence both the timing and the scale of future tax measures.

Labour’s response to energy bills

Both Chancellor Rachel Reeves and Prime Minister Keir Starmer have indicated a willingness to support households if energy prices remain high, though precise details have yet to be announced.


Any potential bailout could carry substantial fiscal consequences, depending on the severity and duration of international price increases. In recent statements, Rachel Reeves has insisted that assistance for struggling families is under active consideration.


However, no formal measures have been confirmed, and the government remains cautious given the legacy of the 2022 fiscal crisis and its impact on investor confidence.

Political shifts in cryptocurrency investment

The debate around fiscal prudence coincides with developments in the cryptocurrency sector. Kwarteng recently announced that Reform UK leader Nigel Farage has invested £215,000 to acquire a 6.3 per cent stake in Stack BTC, a crypto services company chaired by Kwarteng since November. Kwarteng and his wife hold a combined 5.4 per cent interest in the company, worth approximately £185,000.


News of Farage’s investment led to Stack BTC’s share price more than doubling, a development that has attracted attention given Farage’s previously sceptical stance on cryptocurrency.


Kwarteng commented on the controversy, stating, “Politicians are under massive scrutiny which is quite right, but I think just because it’s unusual it doesn’t mean it’s in any way wrong or bad.”

Final Summary

The government faces complex choices as spiralling energy prices, geopolitical instability, and heightened market volatility test the resilience of fiscal policy. Kwasi Kwarteng has cautioned that additional tax rises may be necessary to ensure economic stability if substantial public subsidies are introduced.


At the same time, the political climate concerning investments in emerging areas, such as cryptocurrency, is evolving, with regulatory engagement viewed as key to future growth.


How policymakers balance immediate financial support, tax policy, and investor confidence will remain central to the economic debate. For further market analysis and updates on fiscal policy, readers can access additional resources and insights through the Pie app.
