As expected, the Bank of England (BOE) announced it is increasing its asset purchase program, otherwise known as quantitative easing (QE) by £50 billion. To put that in non-industry terms, the bank will purchase €50 billion in gilts from commercial banks, giving banks more money to lend, which ideally helps the British economy grow faster.
Why did the BOE think this necessary? British GDP growth was rather sluggish in 2011, as shown in Exhibit 1.

Simultaneously, M4 money supply has contracted for 14 straight months, as shown in Exhibit 2, and corporate lending has been negative since 2009, as shown in Exhibit 3. (M4 measures all cash in circulation, held in private-sector retail and wholesale bank and building society deposits, and Certificates of Deposit.) Though the decline in corporate lending has eased lately, suggesting credit is slowly becoming more available to businesses, it appears that wasn’t happening fast enough for the BOE’s comfort.

As the theory goes, if banks have more cash, they can lend more to businesses, who can use the money to finance expansion—whether that’s investing in new equipment, hiring more workers, opening more locations, etc. The result, over time, should be faster economic growth, provided all works as intended.
However, it’s too soon to say whether more lending and faster growth will follow more QE. In the US, the Federal Reserve similarly expanded its QE program in 2010, and banks ended up holding much of that new cash in excess reserves at the central bank, rather than lending it. And last year’s drop in corporate lending coincided with “Project Merlin,” under which the banks agreed to increase lending in 2011.
Thus, we suggest taking the BOE’s announcement with the caveat that even well-intentioned economic policies don’t always work out as planned. No matter how the government tries to facilitate lending and economic growth, market conditions ultimately dictate whether banks lend and how companies deploy cash. That said, we’d consider it positive that the BOE remains accommodative, with an eye toward increasing liquidity at a time many perceive that as necessary. (For more on the topic of central banks, see our recent commentary on iStockAnalyst.com, “Central Bank Accommodations.”)
Also, because the QE increase is small (and M4 has been contracting), it seems unlikely to materially impact the inflation rate, which has eased in early 2012. Exhibit 4 shows the breakdown of the BOE’s balance sheet at yearend. A £50 billion increase in the asset purchase facility (pink) is marginal compared to the overall increase since mid-2008. (Remember, though inflation accelerated in 2011, that was largely due to the VAT increase early that year, as described here.)
