TheLondon Stock Exchange (LSE) is a globalstock exchange based inPaternoster Square in theCity of London, England. Founded in 1801, it is one of the world's oldest continuously operating stock exchanges. As of July 2024, the exchange had a total market capitalisation of approximatelyUS$3.4 trillion of listed companies. Since 2007, it has been part of theLondon Stock Exchange Group (LSEG), which the exchange also lists under the ticker symbol LSEG.[3]
The LSE operates multiple equity and debt markets, including its Main Market for large companies and the Alternative Investment Market (AIM) for smaller and growth-focused firms. Despite a decline in domestic listings followingBrexit, it remained Europe's most valuable stock exchange by overall listed market capitalisation as of 2023.[4][5][6]
According to the 2020Office for National Statistics report, approximately 12% of UK-resident individuals reported having investments in stocks and shares.[7]
In the 17th century, stockbrokers were not allowed in the Royal Exchange due to their perceived rude manners. They had to operate from other establishments in the vicinity, notablyJonathan's Coffee-House. At that coffee house, a broker named John Castaing started listing the prices of a few commodities including salt, coal, paper, and exchange rates in 1698. Originally, this was not a daily list and was only published a few days of the week.[10]
This list and activity was later moved to Garraway's coffee house. Publicauctions during this period were conducted for the duration that a length of tallow candle could burn. These were known as "by inch of candle" auctions. As stocks grew, with new companies joining to raise capital, the royal court also raised some monies. These are the earliest evidence of organised trading in marketable securities in London.

After Gresham's Royal Exchange building was destroyed in theGreat Fire of London, it was rebuilt and re-established in 1669. This was a move away from coffee houses and a step towards the modern model of stock exchange.[11]
The Royal Exchange housed brokers, merchants and merchandise. This was the birth of a regulated stock market, which had teething problems in the shape of unlicensed brokers. In order to regulate these, Parliament passed an Act in 1697 that levied heavy penalties, both financial and physical, on those brokering without a licence. It set a fixed number of brokers, at 100, but this was later increased as the size of the trade grew.
This limit led to several problems, one of which was that traders began leaving the Royal Exchange, either by their own decision or through expulsion, and started dealing in the streets of London. The street in which they were now dealing was known as 'Exchange Alley', or 'Change Alley'; it was suitably placed close to theBank of England. Parliament tried to regulate this and ban the unofficial traders from the Change streets.
Traders became weary of "bubbles" when companies rose quickly and fell, so they persuaded Parliament to pass a clause preventing "unchartered" companies from forming.
After theSeven Years' War (1756–1763), trade at Jonathan's Coffee House boomed again. In 1773, Jonathan, together with 150 other brokers, formed a club and opened a new and more formal "Stock Exchange" in Sweeting's Alley. This now had a set entrance fee, by which traders could enter the stock room and trade securities. It was not an exclusive location for trading, as trading also occurred in the Rotunda of the Bank of England. Fraud was also rife during these times and in order to deter such dealings, it was suggested that users of the stock room pay an increased fee. This was not met well and ultimately, the solution came in the form of annual fees and turning the Exchange into a Subscription room.
The Subscription room created in 1801 was the first regulated exchange in London, but the transformation was not welcomed by all parties. On the first day of trading, non-members had to be expelled by a constable. In spite of the disorder, a new and bigger building was planned at Capel Court.
William Hammond laid the first foundation stone for the new building on 18 May. It was finished on 30 December when "The Stock Exchange" was incised on the entrance.
In the Exchange's first operating years, on several occasions there was no clear set of regulations or fundamental laws for the Capel Court trading. In February 1812, the General Purpose Committee confirmed a set of recommendations, which later became the foundation of the first codified rule book of the Exchange. Even though the document was not a complex one, topics such assettlement anddefault were, in fact, quite comprehensive.
With its new governmental commandments[12] and increasing trading volume, the Exchange was progressively becoming an accepted part of the financial life in the city. In spite of continuous criticism from newspapers and the public, the government used the Exchange's organised market (and would most likely not have managed without it) to raise the enormous amount of money required for the wars against Napoleon.
After the war and facing a booming world economy, foreign lending to countries such as Brazil, Peru and Chile was a growing market. Notably, the Foreign Market at the Exchange allowed for merchants and traders to participate, and the Royal Exchange hosted all transactions where foreign parties were involved. The constant increase in overseas business eventually meant that dealing in foreign securities had to be allowed within all of the Exchange's premises.
Just as London enjoyed growth through international trade, the rest of Great Britain also benefited from the economic boom. Two other cities in particular showed great business development: Liverpool and Manchester. In 1836, both theManchester and Liverpool stock exchanges were opened. Some stock prices sometimes rose by 10%, 20% or even 30% in a week. These were times when stockbroking was considered a real business profession, and such attracted many entrepreneurs. With booms came busts, and in 1835 the "Spanish panic" hit the markets, followed by a second one two years later.
Debenture ofThe Stock Exchange, issued 1 January 1899
By June 1853, both participating members and brokers were taking up so much space that the Exchange was now uncomfortably crowded, and continual expansion plans were taking place. Having already been extended west, east, and northwards, it was decided that the Exchange needed an entire new establishment.Thomas Allason was appointed as the main architect. In March 1854, the new brick building inspired by theGreat Exhibition stood ready. This was a huge improvement in both surroundings and space, with twice the floor space available.
By the late 1800s, the telephone,ticker tape, and thetelegraph had been invented. Those new technologies led to a revolution in the work of the Exchange.
Stock certificate of the London Stock Exchange, issued on 31 March 1920, declared as a qualification share. The capital of the Exchange from its incorporation consisted of 20,000 shares held only by its members, with trustees and directors required to hold 10 qualification shares.
As the financial centre of the world, both the City and the Stock Exchange were hit hard by the outbreak ofWorld War I in 1914. Prices surged at first, due to fears that borrowed money was to be called in and that foreign banks would demand their loans or raise interest. The decision to close the Exchange for improved breathing space and to extend the August Bank Holiday to prohibit a run on banks, was hurried through by the committee andParliament, respectively. The Stock Exchange ended up being closed from the end of July until the New Year, causing street business to be introduced again, as well as the "challenge system".
The Exchange was set to open again on 4 January 1915 under tedious restrictions: transactions were to be in cash only. Due to the limitations and challenges on trading brought by the war, almost a thousand members quit the Exchange between 1914 and 1918. When peace returned in November 1918, the mood on the trading floor was generally cowed. In 1923, the Exchange received its owncoat of arms, with the mottoDictum Meum Pactum, My Word is My Bond.
In 1937, officials at the Exchange used their experiences from World War I to draw up plans for how to handle a new war. The main concerns includedair raids and the bombing of the Exchange's perimeters. One suggestion was a move toDenham, Buckinghamshire. This never took place. On the first day of September 1939, the Exchange closed its doors "until further notice" and two days laterWorld War II was declared. The Exchange opened its doors again six days later, on 7 September.
As the war escalated into its second year, the concerns for air raids were greater than ever. On the night of 29 December 1940,one of the greatest fires in London's history took place. The Exchange's floor was hit by a clutch ofincendiary bombs, which were extinguished quickly. Trading on the floor was now drastically low and most was done over the phone to reduce the possibility of injuries.
The Exchange was only closed for one more day during wartime, in 1945 due to damage from aV-2 rocket. Trading continued in the house's basement.
After decades of uncertain if not turbulent times, stock market business boomed in the late 1950s. This spurred multiple officials to find new, more suitable accommodation. In 1967, work on the newStock Exchange Tower began. The Exchange's new 321 feet (98 metres) high building had 26 storeys with council and administration at the top, and middle floors let out to affiliate companies.Queen Elizabeth II opened the building on 8 November 1972. It was a new City landmark, with its 23,000 sq ft (2,100 m2) trading floor.
1973 marked a year of changes for the Stock Exchange. First, two trading prohibitions were abolished. A report from theMonopolies and Mergers Commission recommended the admittance of both women and foreign-born members on the floor. Second, in March the London Stock Exchange formally merged with the eleven British and Irish regional exchanges, including theScottish Stock Exchange.[13]
This expansion led to the creation of a new position of chief executive officer; after an extensive search this post was given to Robert Fell. There were more governance changes in 1991, when the governing Council of the Exchange was replaced by a board of directors drawn from the Exchange's executive, customer, and user base; and the trading name became "The London Stock Exchange".
TheFTSE 100 Index (pronounced "Footsie 100") was launched by a partnership of theFinancial Times and the Stock Exchange on 3 January 1984. This turned out to be one of the most useful indices of all, and tracked the movements of the 100 leading companies listed on the Exchange.
On 20 July 1990, a bomb planted by theProvisional Irish Republican Army (IRA) exploded in the men's toilets behind the visitors' gallery. The area had already been evacuated and nobody was injured.[14] About 30 minutes before the blast at 8:49 a.m., a man who said he was a member of the IRA toldReuters that a bomb had been placed at the exchange and was about to explode. Police officials said that if there had been no warning, the human toll would have been very high.[15] The explosion ripped a hole in the 23-storey building inThreadneedle Street and sent a shower of glass and concrete onto the street.[16] The long-term trend towardselectronic trading platforms reduced the Exchange's attraction to visitors, and although the gallery reopened, it was closed permanently in 1992.
The biggest event of the 1980s was the sudden de-regulation of the financial markets in the UK in 1986. The phrase"Big Bang" was coined to describe measures, including abolition of fixed commission charges and of the distinction betweenstockjobbers and stockbrokers on the London Stock Exchange, as well as the change from anopen outcry to electronic,screen-based trading.
In 1995, the Exchange launched theAlternative Investment Market, the AIM, to allow growing companies to expand into international markets. Two years later, the Electronic Trading Service (SETS) was launched, bringing greater speed and efficiency to the market. Next, the CREST settlement service was launched.
In 2000, the LSE's shareholders voted to become a public limited company, London Stock Exchange plc. The LSE also transferred its role as the United Kingdom's listing authority to theFinancial Services Authority.
EDX London, an international equity derivatives business, was created in 2003 in partnership with OM Group. The Exchange also acquired Proquote Limited, a new generation supplier of real-time market data and trading systems.

The old Stock Exchange Tower became largely redundant with Big Bang, which deregulated many of the LSE's activities: computerised systems and dealing rooms replaced face-to-face trading. In 2004, the LSE moved to a brand-new headquarters inPaternoster Square, close toSt Paul's Cathedral.
Paternoster Square was the initial target for the protesters ofOccupy London on 15 October 2011. Attempts to occupy the square were thwarted by police.[17] Police sealed off the entrance to the square as it is private property, a High Court injunction having previously been granted against public access to the square.[18] The protesters moved nearby to occupy the space in front ofSt Paul's Cathedral.[19] The protests were part of the globalOccupy movement.
On 25 April 2019, the final day of theExtinction Rebellion disruption in London, 13 activists glued themselves together in a chain, blocking the entrances of the LSE.[20][21] The protesters were all later arrested on suspicion of aggravated trespass.[21] Extinction Rebellion had said its protesters would target the financial industry "and the corrosive impacts of the ... sector on the world we live in" and activists also blocked entrances toHM Treasury and theGoldman Sachs office onFleet Street.[22]
In 2019, the London Stock Exchange introduced the Green Economy Mark, a designation awarded to companies that derive at least 50% of their revenues from environmental or sustainable products and services, with more than 80 issuers receiving the mark by mid-2020.[23]
According to a 2020Financial Conduct Authority report, approximately 15% of British adults reported having investments in stocks and shares.[24]
The main market is home to over 1,300 large companies from 60 countries.[26] TheFTSE 100 Index ("footsie") is the main share index of the 100 most highly capitalised British companies listed on the Main Market.[27]
TheAlternative Investment Market is LSE's international market for smaller companies. A wide range of businesses including early-stage,venture capital-backed, as well as more-established companies join AIM seeking access to growth capital. The AIM is classified as a Multilateral Trading Facility (MTF) under the 2004MiFID directive, and as such it is a flexible market with a simpler admission process for companies wanting to be publicly listed.[28]
Through the Exchange's Italian arm,Borsa Italiana, the London Stock Exchange Group offers clearing and settlement services for trades throughCassa di Compensazione e Garanzia (CC&G) andMonte Titoli.[30][31] It is the Groups Central Counterparty and covers multiple asset classes throughout the Italian equity, derivatives and bond markets.
CC&G also clears Turquoise derivatives.Monte Titoli is the pre-settlement, settlement, custody and asset services provider of the Group. Monte Titoli operates both on-exchange and OTC trades with over 400 banks and brokers.
Their previous trading platformTradElect was based on Microsoft's.NET Framework, and was developed by Microsoft and Accenture.[33]
In 2009, despite TradElect only being in use for about two years,[34] after suffering multiple periods of extended downtime and unreliability[35][36] the LSE announced that it was planning to switch to Linux in 2010.[37][38] In February 2011, the main market migration to MillenniumIT technology was successfully completed.[39]
In October 1997, the previous system, SETS, was introduced and used until 2007.[40]
The London Market Information Link, aCOBOL application running on aHPTandem server, was used to disseminate market data to terminals before being replaced by Infolect.[37]
The LSE facilitates stock listings in a currency other than its "home currency". Most stocks are quoted in GBP but some are quoted in EUR while others are quoted in USD.[citation needed]
The LSE hosts numerous Israeli tech companies,[41] which, according to the UK-Israel Tech Hub, have been instrumental in boosting its growth and fostering bilateral economic ties.[42] LSE CEOJulia Hoggett has commended the Israeli tech sector, highlighting the importance ofhigh tech companies trading on the LSE.[43][44]
On 3 May 2000, it was announced that the LSE would merge with theDeutsche Börse; however this fell through.[45]
On 23 June 2007, the LSE announced that it had agreed on the terms of a recommended offer to the shareholders of theBorsa Italiana S.p.A. The merger of the two companies created a leading diversified exchange group in Europe. The combined group was named the London Stock Exchange Group, but still remained two separate legal and regulatory entities. One of the long-term strategies of the joint company is to expand Borsa Italiana's efficient clearing services to other European markets.
In 2007, after Borsa Italiana announced that it was exercising its call option to acquire full control of MBE Holdings; thus the combined Group would now control Mercato dei Titoli di Stato, or MTS. This merger of Borsa Italiana and MTS with LSE's existing bond-listing business enhanced the range of covered European fixed income markets.
In 2009, the London Stock Exchange Group acquiredTurquoise, a Pan-European MTF.[46]
On 9 October 2020, the LSE agreed to sell the Borsa Italiana (including Borsa's bond trading platform MTS) toEuronext for €4.3 billion (£3.9 billion) in cash.[47] Euronext completed the acquisition of the Borsa Italiana Group on 29 April 2021, for a final price of €4,444 million.[48]
On 12 December 2022, Microsoft bought a nearly 4% stake in London Stock Exchange Group as part of a ten-year cloud deal.[49]
In December 2005, the LSE rejected a £1.6 billion takeover offer fromMacquarie Bank. It described the offer as "derisory", a sentiment echoed by shareholders in the Exchange. Shortly after Macquarie withdrew its offer, the LSE received an unsolicited approach fromNASDAQ valuing the company at £2.4 billion. This too it rejected. NASDAQ later pulled its bid, and less than two weeks later on 11 April 2006, struck a deal with LSE's largest shareholder,Ameriprise Financial'sThreadneedle Asset Management unit, to acquire all of that firm's stake, consisting of 35.4 million shares, at £11.75 per share.[50]
NASDAQ purchased 2.69 million additional shares, resulting in a total stake of 15%. While the seller of those shares was undisclosed, it occurred simultaneously with a sale byScottish Widows of 2.69 million shares.[51] The move was seen as an effort to force LSE to the negotiating table, as well as to limit the Exchange's strategic flexibility.[52]
Subsequent purchases increased NASDAQ's stake to 25.1%, holding off competing bids for several months.[53][54][55] United Kingdom financial rules required that NASDAQ wait for a period of time before renewing its effort. On 20 November 2006, within a month or two of the expiration of this period, NASDAQ increased its stake to 28.75% and launched a hostile offer at the minimum permitted bid of £12.43 per share, which was the highest NASDAQ had paid on the open market for its existing shares.[56] The LSE immediately rejected this bid, stating that it "substantially undervalues" the company.[57]
NASDAQ revised its offer, characterised as an "unsolicited" bid, rather than a "hostiletakeover attempt", on 12 December 2006, indicating that it would be able to complete the deal with 50%, plus one share, of LSE's stock, rather than the 90% it had been seeking. The U.S. exchange did not raise its bid. Manyhedge funds had accumulated large positions within the LSE, and many managers of those funds, as well as Furse, indicated that the bid was still not satisfactory. NASDAQ's bid was made more difficult because it had described its offer as "final", which, under British bidding rules, restricted their ability to raise its offer except under certain circumstances.
In the end, NASDAQ's offer was roundly rejected by LSE shareholders. Having received acceptances of only 0.41% of rest of the register by the deadline on 10 February 2007, Nasdaq's offer duly lapsed.[58]
On 20 August 2007, NASDAQ announced that it was abandoning its plan to take over the LSE and subsequently look for options to divest its 31% (61.3 million shares) shareholding in the company in light of its failed takeover attempt.[59] In September 2007, NASDAQ agreed to sell the majority of its shares toBorse Dubai, leaving theUnited Arab Emirates-based exchange with 28% of the LSE.[60]
On 9 February 2011, London Stock Exchange Group announced it had agreed to merge with theToronto-basedTMX Group, the owners of theToronto Stock Exchange, creating a combined entity with a market capitalisation of listed companies equal to £3.7 trillion.[61]Xavier Rolet, CEO of theLSE Group at the time, would have headed the new enlarged company, while TMX Chief Executive Thomas Kloet would have become the new firm president. On 29 June 2011, the LSE Group however announced it was terminating the merger with TMX, citing that "LSEG and TMX Group believe that the merger is highly unlikely to achieve the required two-thirds majority approval at the TMX Group shareholder meeting".[62] Even though LSEG obtained the necessary support from its shareholders, it failed to obtain the required support from TMX's shareholders.
Normal trading sessions on the main orderbook (SETS) are from 08:00 to 16:30 local time every day of the week except Saturdays, Sundays and holidays declared by the exchange in advance. The detailed schedule is as follows:
