Extract A: Bank of England Balance Sheet and Asset Purchase Facility (APF) holdings

Extract B: The Mechanics of Unconventional Monetary Intervention

With the Bank Rate compressed close to its effective lower bound of 0.10% during the pandemic economic shock, the Monetary Policy Committee (MPC) could no longer rely solely on conventional interest rate cuts to stimulate aggregate demand. To prevent a severe deflationary spiral and support liquidity, the Bank of England aggressively expanded its asset purchase program.

The process involves the central bank creating digital money to purchase high-quality financial assets—primarily government bonds (gilts) and some high-grade corporate debt—from financial institutions. This large-scale purchasing drives up the price of these bonds, which conversely lowers their yields. Consequently, this lowers borrowing costs across the wider financial system, encouraging commercial banks to extend credit and motivating investors to reallocate portfolios toward riskier, higher-yielding assets like corporate equities and physical capital investments.

Extract C: The Dual Mandate and the Pathway to Normalisation

As supply-side bottlenecks and surging global energy prices drove CPI inflation well above the 2.0% target in late 2021, the MPC shifted its stance. Monetary policy actions turned toward anchoring inflation expectations and curbing excess aggregate demand.

In addition to raising the policy interest rate, the central bank initiated a strategy of quantitative tightening (QT). Unlike quantitative easing, which injects substantial liquidity into the banking system, QT allows matured gilts to roll off the balance sheet without reinvestment, or involves direct asset sales back to the market. This absorbs liquidity, increases long-term interest rates, and reinforces the restrictive stance of conventional policy rate hikes to secure long-term price stability.
