Overview
Scottish Mortgage Investment Trust is a publicly traded UK investment trust whose portfolio is built around global businesses expected to generate strong, above-average returns over the long term. The trust is listed on the London Stock Exchange and is a constituent of the FTSE 100 Index. It is managed by Baillie Gifford & Co Limited, the Edinburgh-based investment management partnership that originated the trust. The trust began in 1909 during the aftermath of the Panic of 1907. Credit was difficult to obtain, while the expanding motorcar industry was increasing demand for rubber and tyres. Baillie and Gifford identified an opportunity to lend against rubber estates in Southeast Asia and established The Straits Mortgage and Trust Company Limited for that purpose. The anticipated specialist lending market developed differently from expectations. As the credit crisis eased, rubber planters required less financing, and the trust's original business model became less compelling. In 1913, the board broadened the remit to include bonds and equities from markets around the world and changed the name to The Scottish Mortgage and Trust Company Limited. The change transformed the organisation from a specialist lender into a conventional international investment trust. Early holdings included oil and railway companies as well as government loans connected with Argentina, India, China and the Ottoman Empire. From its earliest decades, overseas investing was central to the trust's identity, with North America becoming particularly important. The portfolio changed in response to economic and political conditions. During the 1930s, European holdings were reduced as political tensions worsened and proceeds were directed toward North American securities. By 1940, about 22 percent of the portfolio was invested in US companies, although wartime British controls subsequently required the sale and repatriation of American securities owned by British citizens. The US allocation fell to 6.6 percent by 1942 and was rebuilt during the post-war period. By 1957, investments in the United States and Canada represented more than 44 percent of assets. Scottish Mortgage also participated early in the opening of Japan's investment market to foreign investors during the 1960s. In the 1970s, the trust reduced its relative exposure to UK equities and bonds, reflecting both the poor performance of the UK market and a deliberate preference for overseas opportunities. This international orientation remains a defining characteristic. In the modern era, the trust describes its philosophy as investing in progress. It seeks companies and entrepreneurs that are building or benefiting from long-term changes in the economy, rather than limiting the portfolio to a particular country or industry. Its holdings have included listed technology, consumer, healthcare and industrial businesses, together with selected private companies. The trust can allocate up to 30 percent of its value, measured at the time of investment, to private companies. Examples cited in reference material include SpaceX and ByteDance. Scottish Mortgage reached its centenary in 2009. Its investment interests continued to extend across developed and emerging markets, including China and Brazil. Reference material reported total net assets of approximately £14.6 billion as of 20 August 2020 and approximately £19.5 billion as of 30 September 2021. These figures are historical and should not be treated as current assets under management. Dividend continuity is another notable feature of the trust's history. It has reduced its dividend only once, in 1933, after the Depression severely affected its portfolio. In other years it maintained or increased the dividend, including during the two World Wars. The trust's long history therefore combines a global mandate, a willingness to invest through major economic disruptions and a growth-oriented approach managed by Baillie Gifford.
History
Scottish Mortgage Investment Trust originated in Edinburgh in 1909, when Colonel Augustus Baillie and Carlyle Gifford established The Straits Mortgage and Trust Company Limited. The enterprise was created during a period when credit markets remained constrained after the Panic of 1907. At the same time, the growing popularity of motorcars, including the Ford Model T, was stimulating demand for rubber. The founders intended to provide secured loans to rubber planters in Southeast Asia, using rubber estates as collateral. The original lending opportunity did not develop as expected. Credit conditions improved, and the planters no longer needed financing on the scale anticipated. Within several years, the trust therefore moved away from its specialist mortgage purpose. In 1913, its investment remit was expanded to encompass worldwide bond and equity markets, and its name became The Scottish Mortgage and Trust Company Limited. This was the decisive transition from a rubber-finance vehicle to an international investment trust. The early portfolio reflected the industrial and imperial economy of the period. It included oil and railway companies and loans to governments associated with Argentina, India, China and the Imperial Ottoman state. North American investments were present from the beginning and became increasingly significant. During the 1930s, the trust sold European investments as political conditions deteriorated and redirected capital toward North America. By 1940, US securities accounted for approximately 22 percent of the portfolio. The Second World War interrupted that development. The British government required British owners to sell and repatriate American securities, and Scottish Mortgage's US exposure declined to approximately 6.6 percent by 1942. The allocation was rebuilt after the war as international equity markets recovered. By 1957, more than 44 percent of the trust's assets were invested in the United States and Canada, demonstrating the board's long-standing willingness to place substantial capital outside the United Kingdom. During the 1960s, Scottish Mortgage was among the investors to take advantage of the relaxation of restrictions on foreign investment in Japan. The decision was financially successful according to the reference history, although it occurred while memories of the war remained politically and socially sensitive. In the early 1970s, UK equities and bonds represented about 63 percent of the trust in 1972 but roughly 45 percent two years later. The reduction reflected both the relative fall in UK markets and a deliberate strategic preference for overseas opportunities. The trust celebrated its hundredth anniversary in 2009. Its later portfolio continued to span the world, including rapidly developing economies such as China and Brazil. The modern investment philosophy is expressed as investing in progress: identifying companies and entrepreneurs that may shape future economic activity and can deliver strong returns over extended periods. The portfolio may contain both publicly traded companies and private businesses, with private-company exposure capped at 30 percent of the trust's value at the time of investment. The trust's dividend record is unusually persistent. It cut its dividend once, in 1933, following the damage caused by the Great Depression. Outside that year, the dividend was maintained or increased, including through both World Wars. Historical reference material reported total net assets of approximately £14.6 billion on 20 August 2020 and approximately £19.5 billion on 30 September 2021. Scottish Mortgage is managed by Baillie Gifford & Co Limited, remains listed on the London Stock Exchange and is included in the FTSE 100 Index.
