Late-2000s financial crisis: The Northern Rock bank received a liquidity support facility from the Bank of England, sparking a bank run—the United Kingdom's first in 150 years.

The 2008 financial crisis, also known as the global financial crisis (GFC) or the Panic of 2008, was a major worldwide financial crisis centered in the United States. The causes included excessive speculation on property values by both homeowners and financial institutions, leading to the 2000s United States housing bubble. This was exacerbated by predatory lending for subprime mortgages and by deficiencies in regulation. Cash out refinancings had fueled an increase in consumption that could no longer be sustained when home prices declined. The first phase of the crisis was the subprime mortgage crisis, which began in early 2007, as mortgage-backed securities (MBS) tied to U.S. real estate, and a vast web of derivatives linked to those MBS, collapsed in value. A liquidity crisis spread to global institutions by mid-2007 and climaxed with the bankruptcy of Lehman Brothers in September 2008, which triggered a stock market crash and bank runs in several countries. The crisis exacerbated the Great Recession, a global recession that began in mid-2007, as well as the United States bear market of 2007–2009. It was also a contributor to the 2008–2011 Icelandic financial crisis and the euro area crisis.

Northern Rock, formerly the Northern Rock Building Society, was a British bank. Based at Regent Centre in Newcastle upon Tyne, United Kingdom, Northern Rock was originally a building society. It demutualised and became Northern Rock bank in 1997, when it floated on the London Stock Exchange with the ticker symbol NRK.

The discount window is an instrument of monetary policy that allows eligible institutions to borrow money from the central bank, usually on a short-term basis, to meet temporary shortages of liquidity caused by internal or external disruptions.

The Bank of England is the central bank of the United Kingdom and the model on which most modern central banks have been based. Established in 1694 to act as the English Government's banker and debt manager, and still one of the bankers for the government of the United Kingdom, it is the world's second oldest central bank.
