Guernsey's economy: an island that sells the difference in its laws

How Guernsey profited from gaps in English law

The Bailiwick of Guernsey is a Crown dependency outside the United Kingdom, and until the 19th century its position left it generally exempt from the harsher parts of Westminster legislation while still inside favourable policies such as English protectionism. Guernsey's earliest trades turned that position into income. Around 1700 small Guernsey ships left the Newfoundland cod trade because buying goods in for sale to smugglers paid better, and when smuggling declined at the end of the 18th century, licensed privateering took over. The island's history follows those wars in detail.

The same arithmetic brought manufacturers. James Keiller of Dundee set up in Guernsey in 1857 to avoid the United Kingdom's duty on sugar and stayed until 1879, shipping marmalade made on the island all over the world. Other light industry arrived on similar terms and left after a few decades. The electronics firm Tektronix worked in Guernsey from 1957 to the 1980s, Specsavers Optical Group, established in 1984, is based on the island, and Healthspan has its headquarters there.

After 1945 the islanders looked for new trades because fishing and quarrying did not return after the occupation, and moving goods in and out was difficult because the harbours were too small and freight too expensive. What could be moved cheaply was the right to trade. A Guernsey business came to control the right to supply Mateus Rosé to the United Kingdom.

The mail-order version of the same idea lasted into the 21st century. Low Value Consignment Relief let businesses in Guernsey post small parcels to customers in the United Kingdom without VAT. The United Kingdom announced its end in the 2011 Budget, and the change took effect on 1 April 2012. Each of these trades earned money from a rule written somewhere else.

Why Guernsey stopped exporting tomatoes

For about a century Guernsey also exported things it made from its own ground. In the 19th century Guernsey granite was prized in London, where London Bridge and many of the main roads were repaved with it, and hundreds of quarries opened in the northern parishes. Horticulture began in glasshouses built for grapes and moved to tomatoes, and from the 1860s it was a very important industry on the island. Britannica describes the division of the land that followed: greenhouses in the low north growing tomatoes, flowers and grapes, mostly for England, and dairy farming with the island's own breed of cattle on the high ground of the south.

The occupation left the growing industry damaged, and by the 1960s the industry had recovered to the point of exporting 500 million tomatoes a year. Two changes in fuel then ended it. The oil price rises of the 1970s pushed up the cost of heating glass, and cheap North Sea gas gave Dutch growers heat at a price Guernsey growers could not match. The tomato trade was gone by the end of the 1970s, a hundred years after it began. Horticulture in cut flowers, freesias especially, has declined as well.

The national accounts show what is left. In 2019 agriculture, horticulture, fishing and quarrying together made up 0.2% of Guernsey's GDP, and in June 2020 the sector employed 438 people. The move from the growing industry into offices is recorded as a hard transition for the people who made it.

What Guernsey's national accounts measure

The States of Guernsey's Data and Analysis service estimates output by the income approach, adding up wages, company trading surpluses, the income of sole traders and households' rental income. By that measure Guernsey's GDP was £3,488 million in 2023, 5% higher than in 2022 in nominal terms and 2% lower in real terms once deflated by the island's Retail Price Index. GDP per head was £54,463 in 2023. Gross value added at basic prices, before product taxes such as import duties and harbour dues, came to £3,414 million in 2023.

Pay is the larger half of that output. Compensation of employees was 50% of GDP in 2023 and gross operating surplus, broadly company profit, was 36%. Gross operating surplus is the component that swings from year to year, and it was 40.6% of GDP in 2019.

Finance produced £1,304 million in 2023, or 37% of GDP and 42% of factor income, the total that leaves out households. The Data and Analysis service also publishes a wider figure. Adding the legal, accounting, actuarial, tax and company secretarial work done for finance firms brings the total to £1,524 million in 2023, which the States put at 44% of GDP. In 2023 manufacturing and information and communication were the two industry sectors whose value added fell in nominal terms.

The sector breakdown for 2019, the latest year the 2020 economic overview set out in full, sets finance against every other sector.

Growth has followed finance closely. First estimates put real growth at 0.3% in 2019, and the 2020 overview forecast a contraction of between 5% and 8% in 2020, with finance alone taking 2.8 percentage points off GDP in the central forecast.

How Guernsey's finance sector divides its work

The States split finance into four parts: banking, fiduciaries, funds and insurance. In June 2020 fiduciaries employed 29% of the sector's workers, banks 28%, funds 22% and insurance 13%, with brokers and money service firms making up the other 8%. The balance had shifted over the preceding years as banking contracted worldwide and the other three grew locally. The Guernsey Financial Services Commission, established in 1987, regulates all four.

Why banks came to Guernsey

Banks began setting up on the island in the early 1960s to avoid high onshore taxes and restrictive regulation. There were 22 of them in June 2020, holding banking assets of £110 billion. At that date 68% of those assets were interbank loans, which the States attribute to the up-streaming model many Guernsey institutions use.

What Guernsey funds hold

The fund figures are large beside the island's own output. The net asset value of Guernsey funds was £270.0 billion at the end of June 2026, about 77 times the island's GDP for 2023. Closed-ended funds held £224.2 billion of that across 756 schemes, and the States reported in 2020 that most closed-ended schemes regulated in Guernsey are private equity funds. The open-ended sector held £45.8 billion across 131 schemes. Guernsey Sustainable Funds accounted for £4.3 billion at the same date.

The comparable total for June 2020 was £269 billion, a figure that also counted £39 billion of funds incorporated in other jurisdictions and administered on the island. Over the year to June 2026 net asset values fell by just under £0.9 billion, or 0.3%.

How captive insurance uses the island

Insurers based in Guernsey held gross assets of £31.4 billion at the end of 2019 and wrote £5.0 billion of premiums in that year. Captive insurance was the dominant activity in the international market in 2019, although the number of companies doing it was falling. At the end of 2019 there were 627 insurance vehicles on the register, 281 of them cells of protected cell companies, down from 649 vehicles a year earlier.

How Guernsey taxes companies and residents

Guernsey, Alderney and Sark each raise their own taxes, although Alderney transferred its fiscal rights to Guernsey in 1949. Since 2008 Guernsey has charged company profits at three rates depending on where the income comes from. Most companies pay 0%. Banking income pays 10%, and from 1 January 2013 the 10% rate was extended to domestic insurance, fiduciary work, insurance intermediaries and insurance managers. Regulated utilities and income from land and buildings pay 20%.

Residents pay income tax at 20% on their worldwide income, and every resident's liability has an upper limit. From 1 January 2019 the caps stood at £130,000 on foreign-source income or £260,000 on worldwide income, and new residents who buy an Open Market Part A house can instead cap their bill at £50,000 for three years. Income from Guernsey land and property has sat outside the cap since 1 January 2015.

The absence of capital gains tax, inheritance tax, capital transfer tax, VAT and a general withholding tax is why Guernsey has been described as a tax haven. The States of Guernsey describe the island as an international finance centre. Social insurance applies to everyone over school-leaving age and is charged on gross earnings between upper and lower limits.

Who works in Guernsey and what they earn

Guernsey had 32,291 people in employment in March 2016, 4,864 of them self-employed, and 19.6% of them worked in finance. Median earnings at that date were £31,215. By June 2020 employment was 31,119, after a fall of 4.5% in a year that included the first Covid-19 lockdown.

The June 2020 figures show where the money in the economy lands. Finance employed 5,982 people on median earnings of £48,000, against £34,600 for the whole economy. Public administration employed 5,429 on £37,300. Wholesale and retail employed 3,758 on £23,800, and hostelry 1,562 on £21,100, after losing 24.1% of its jobs in twelve months. Construction and wholesale and retail together made up about 21% of employment in 2020 and take on many of the people who leave school before 18.

Covid-19 support showed the same split. By 20 November 2020 the States had paid £43.7 million to businesses and the self-employed, and 24% of it went to hostelry, a sector that makes 1.8% of output. Finance lost 4.9% of its jobs in the year to June 2020, mostly in banking and mostly in junior posts, which pushed its median pay up by 1.9% in real terms.

After the tomato industry collapsed in the 1970s the States restricted the right to move to the island, for fear of a large rise in population. Housing is sold and let in two markets, a local market and an open market, and in the third quarter of 2020 both drew more transactions at higher real prices than a year earlier. In 2020 local market rents stayed high against the average for England and Wales, comparable to the South East of England. Guernsey's population was 67,787 on 1 January 2024.

Why Guernsey issues its own pounds

Guernsey has no central bank, and it issues its own sterling coins and banknotes, which circulate alongside British notes and coins. The arrangement is older than the finance industry. In 1813 the States asked the Privy Council for permission to issue a Guernsey coinage. When the first coins appeared in 1830 they had been struck by R. Boulton and Co. of Birmingham, and French currency remained legal tender in Guernsey until 1921. In 1815 the States created money free of debt to pay for building roads.

The States have seldom borrowed on the bond market. A 30-year bond for £330 million issued in December 2015 was the island's first in 80 years. The island's investment funds, which pay for pensions and future public costs, stood at £2.7 billion in June 2016.

The States own much of the island's machinery outright. Water, wastewater, the two main harbours and the airport are run by the States, and Guernsey Electricity and Guernsey Post are commercial companies the States wholly own. Guernsey Post has run the island's postal service since the Royal Mail gave it up in 1969. Power arrives mostly by submarine cable from continental Europe through the Channel Islands Electricity Grid, which Guernsey and Jersey formed in 1998, with island diesel generators kept as back-up. The States completed the purchase of the airline Aurigny on 15 May 2003 to protect the air links. The telephone company went the other way: Guernsey Telecoms was sold to Cable and Wireless, which rebranded it as Sure, and Sure was sold to Batelco in April 2013.

What visitors spend in Guernsey

Tourism is older than finance. The first tourist guide to Guernsey was published in 1834, and in the 19th century two British railway companies ran rival steamers from England to St Peter Port until the sinking of the SS Stella in 1899. The trade shrank in the 1980s when a holiday in Spain became much cheaper than one in Guernsey, and the island moved to the higher-priced end of the market.

The States counted 282,028 visitors in 2025, and visitor spending in the year from April 2025 to March 2026 was estimated at £149 million. Visitors from the United Kingdom spent £106 million of that, 72% of the total. Accommodation took £39 million, travel to and from the island £35 million and eating and drinking out £27 million. Leisure visitors spent an average of £703 each in 2025 to 2026, business visitors £698.

Most visitors come by air. In 2025 aircraft carried 333,164 passengers and ferries 151,718, counting residents as well as visitors. Cruise ships brought 28,397 people in 2025, 26% fewer than in 2024. France is the market that grew: 28,029 visitors gave France as their country of residence in 2025, 69% more than in 2024. The hostelry sector that serves them made up 1.8% of GDP in 2019, against 39.8% for finance.

Where Guernsey wants its finance sector to go

On 19 September 2025 the Committee for Economic Development, the Guernsey Financial Services Commission, Guernsey Finance and the Guernsey International Business Association announced a joint Finance Sector Policy Framework. The consultancy Oliver Wyman won the tender, and the work was due to finish in the first quarter of 2026. The announcement names fintech, digital assets and sustainable finance as areas of growing attention beside funds, private wealth management and insurance, and the brief covers skills gaps and the regulatory, legal and operational framework.

The regulator's statement in the same announcement cited the result of a Moneyval assessment the previous February as the foundation for the work. The Bailiwick was never a member of the European Union, and Guernsey's constitutional and trading relationship with the United Kingdom was largely unaffected by Brexit. Before Brexit it had a special relationship with the European Union under Protocol 3 of the United Kingdom's Treaty of Accession of 1972, and in 2010 Guernsey and Jersey opened a joint office in Brussels to promote economic links with it.
