HookForty-nine days that repriced every mortgage in Britain
On 23 September 2022, Chancellor Kwasi Kwarteng announced a 'mini-Budget': roughly £45bn of unfunded tax cuts, aimed at growth. Markets delivered their verdict within days. The pound touched an all-time low of about $1.03; the government's borrowing costs spiked so violently that the Bank of England had to launch an emergency gilt-buying operation — pledging up to £65bn — to stop a spiral in pension funds; and lenders pulled roughly a thousand mortgage deals in a week as they scrambled to reprice. Kwarteng lasted 25 more days. Liz Truss resigned after 49 as Prime Minister, the shortest premiership in British history.
What killed the policy was not the arithmetic of any single tax cut — it was the contradiction. One arm of the state pressed the fiscal accelerator while the Bank of England was pressing the monetary brake against inflation running near 10%, and markets refused to finance the difference. That is section 2.6 in one story: governments carry a list of objectives, hold two main levers, and discover that the levers pull against each other. Learn the list, the levers, and the conflicts — in that order.
ModelThe objectives — the scorecard governments are judged on
The standard list: steady economic growth (UK trend growth is usually put at roughly 2% a year in real terms); low unemployment; low and stable inflation — the explicit target is 2% on the CPI; sustainable public finances (the deficit and the national debt); balance of payments stability; protection of the environment (the UK legislated a net-zero-by-2050 target in 2019); and reduced inequality. Learn it as a checklist — data questions reward candidates who can say which objectives a policy serves and which it sacrifices.
The sharper point: the weights are political choices, and they move. The 2010s put deficit reduction first — austerity. Spring 2020 put jobs first at any fiscal cost — furlough alone cost roughly £70bn. By late 2022 inflation-fighting outranked everything, even growth. When an exam question asks whether a policy is 'good', the honest answer is always: good for which objective, at whose expense — governments are not failing when objectives conflict; the conflict is the normal condition of policy.
ModelThe instruments — two levers, two institutions
Fiscal policy is the government's own lever: spending and taxation, set by the Chancellor at Budgets, with the costings scrutinised by the independent Office for Budget Responsibility (created 2010). In circular-flow terms — the 2.5 link — government spending is an injection and taxation a withdrawal, so fiscal policy adjusts the flow directly. The mini-Budget's fatal procedural choice was skipping the OBR forecast entirely: markets were asked to take £45bn on trust, and declined.
Monetary policy belongs to the Bank of England, operationally independent since 1997 precisely so that interest rates are not set to win elections. The Monetary Policy Committee — nine members, eight meetings a year — sets Bank Rate, and in crises has added quantitative easing: creating money to buy bonds, which peaked at £895bn of assets. The transmission runs through borrowing costs: Bank Rate moves mortgage and loan rates, which moves what households have left to spend, which moves demand and eventually prices.
A household holds a £200,000 tracker mortgage. Bank Rate rises from 1% to 4%. Extra interest ≈ £200,000 × 0.03 = £6,000 a year — £500 a month gone from that family's spending power, without a single vote in Parliament. Scale it up: roughly two million UK households were on variable or tracker deals during the 2022–23 rises, and millions more repriced as fixed deals expired. That is the transmission mechanism in miniature: one committee decision, felt at kitchen tables within weeks — and the calculation is a favourite 2- or 4-marker: rate change × principal, then interpret.
MechanismConflicts and trade-offs — why the levers fight
The defining trade-off of 2021–24 was inflation versus growth and jobs. The MPC raised Bank Rate at 14 consecutive meetings, from 0.1% in December 2021 to 5.25% by August 2023. It worked — inflation fell from its 11.1% peak in October 2022 back to 2.0% by May 2024 — but the bill was real: the average two-year fixed mortgage peaked near 6.85% in summer 2023, growth flatlined, and the second half of 2023 produced a shallow technical recession. Squeezing spending to squeeze prices means squeezing someone's job and someone's mortgage; that is the mechanism, not a side effect.
Public finances versus growth: the 2010s austerity programme cut the deficit from roughly 10% of GDP in 2009–10 to about 2% by 2018–19 — while the recovery ran among the slowest on record, and economists still argue how much of that austerity caused. Growth versus the environment: faster output usually means more energy, more construction, more emissions, unless growth is deliberately steered. And inflation-fighting versus equality: rate rises concentrate pain on younger, mortgaged households, while the QE that rescued the economy after 2008 and 2020 lifted asset prices — houses, shares — mostly owned by the already-wealthy. Every instrument redistributes; the exam rewards you for saying to whom.
CaseReading the mini-Budget like an examiner
Run the September 2022 episode through the 2.6 framework and you have a model answer. Objective pursued: growth. Instrument: fiscal loosening — roughly £45bn of tax cuts. Conflicts triggered: three at once. Inflation — stimulating demand with CPI near 10% meant markets immediately priced in even higher interest rates. Public finances — the cuts were unfunded and un-audited, so gilt yields jumped as lenders demanded a premium for lending to Britain. And the instrument clash — fiscal accelerator against monetary brake, each cancelling the other's credibility.
Outcome: borrowing costs rose so far, so fast, that the growth policy destroyed the conditions for growth — mortgage rates jumped, investment froze, and within weeks the new Chancellor, Jeremy Hunt, reversed almost the entire package on 17 October 2022. The pound and gilt markets calmed almost immediately.
The transferable lesson for evaluation: policies are not judged in isolation but against the state of the cycle (stimulus in an overheating economy is fuel on a fire), the credibility of the institutions behind them (the skipped OBR forecast cost more than any tax cut), and time lags — interest rate changes take roughly 18–24 months to work fully through the economy, which is why the MPC aims at where inflation will be, not where it is. An answer that names the objective, traces the instrument's transmission, and weighs the specific trade-off with a dated example is a level-4 answer by construction.

ExamWhat examiners want
Build chains with a named instrument and a named transmission: 'Bank Rate rises → monthly mortgage repayments rise → discretionary spending falls → demand cools → price rises slow'. Edexcel B rewards each link stated, not the conclusion asserted. Get the institutional furniture exactly right — 2% CPI target, MPC, OBR, Bank independence since 1997 — because precision here is cheap and signals command of the whole topic.
On 8- and 12-markers, the evaluation IS the trade-off: name the objective sacrificed, the group that bears the cost, and the conditions the judgement depends on — the state of the cycle, time lags, and credibility. The 2021–24 rate cycle and the September 2022 mini-Budget are gifts here: dated, numerical, and each a complete worked case of policy conflict. If the extract hands you Bank Rate and an inflation figure, anchor every paragraph to those two numbers — examiners consistently place data-anchored answers a level above generic ones.
