What this dot point is asking
OCR wants you to explain monetary policy (interest rates and the transmission mechanism, and quantitative easing), the role of the central bank and the inflation target, the functions of the financial sector, and why the financial sector is regulated.
Interest rates and the transmission mechanism
The central bank and the inflation target
In the UK, the government sets the inflation target (2 per cent CPI), and the independent Bank of England, through its Monetary Policy Committee, sets interest rates to meet it. Central-bank independence is valued because it removes the temptation for politicians to cut rates for short-term electoral gain, anchoring inflation expectations and giving policy credibility. If inflation misses the target by more than one percentage point, the Bank's Governor must explain why.
Quantitative easing
QE was used heavily after 2008 and during the pandemic. Its risks include inflating asset prices (worsening wealth inequality) and being hard to unwind ("quantitative tightening").
The functions of the financial sector
The financial sector (banks, building societies, insurers and markets) performs several essential roles: it channels funds from savers to borrowers, provides liquidity and a means of payment, maturity-transforms (lending long while funding short), manages and spreads risk (insurance, diversification), and prices assets. A well-functioning financial sector supports investment and growth; a malfunctioning one can trigger deep recessions.
Financial regulation
The financial sector is heavily regulated (in the UK by the Bank of England, the Prudential Regulation Authority and the Financial Conduct Authority) because it is prone to market failure: asymmetric information, moral hazard (banks taking risks knowing they may be bailed out), systemic risk (one failure cascading through the system), and negative externalities on the wider economy. The 2008 financial crisis showed how light regulation and excessive risk-taking can impose enormous costs, prompting higher capital requirements and stress testing.
Examples in context
- The 2022 to 2023 tightening. The Bank of England raised Bank Rate sharply to bring inflation back toward 2 per cent, the transmission mechanism in action.
- Post-2008 QE. The Bank created hundreds of billions of pounds to buy bonds, supporting demand when rates were near zero.
- Post-crisis regulation. Higher bank capital requirements and stress tests were introduced to reduce systemic risk after 2008.

OCR H460/02 20215 marksExplain how a rise in the central bank's interest rate is intended to reduce inflation.Show worked answer →
A short structured question. State that the central bank raises its policy interest rate (Bank Rate) to tighten monetary policy when inflation is above target.
Develop the transmission mechanism: a higher rate raises the cost of borrowing and the reward for saving, so consumption and investment fall; it can raise the exchange rate (hot money inflows), cutting net exports; and it reduces the value of assets, dampening wealth effects. Lower consumption, investment and net exports reduce aggregate demand, shifting AD left, which eases demand-pull inflation. Draw AD shifting left, lowering the price level.
Markers reward at least two channels of the transmission mechanism, the fall in AD, and the link to lower inflation.
OCR H460/02 202312 marksAssess the effectiveness of monetary policy compared with fiscal policy in controlling inflation.Show worked answer →
A levels-of-response question. Knowledge and application: define monetary policy (interest rates, QE, set by an independent central bank to hit the inflation target) and contractionary fiscal policy (higher taxes, lower spending). Explain how each reduces AD and inflation.
Analysis: monetary policy is flexible and can be changed monthly by the independent Bank, with credibility anchoring expectations; fiscal policy directly cuts demand but is slow and politically hard.
Evaluation: monetary policy faces a liquidity-trap limit at low rates and long, variable lags, and blunt effects across the economy; fiscal policy can target but worsens the deficit and is lag-prone. Conclude with a supported judgement: monetary policy is usually the front-line tool for inflation because of flexibility and independence, but it has limits, so the two can be complementary.
