HM Treasury

• 1. Introduction

  ›

  HM Treasury is officially one of the smallest departments in the British government by staff count, yet it is widely regarded as the most powerful. That tension sits at the heart of what makes this institution so unusual. A ministry with fewer employees than many local councils somehow sets the economic direction for an entire nation, controls what every other department can spend, and shapes the conditions under which millions of people work, borrow, and save. How did a medieval counting table covered in chequered cloth become the nerve centre of the world's sixth-largest economy? And what does it mean that, in 2022, the sacking of a single civil servant was described as unprecedented in Treasury history? Those are the questions this documentary will answer.

• 2. A Chequered Cloth and a Counting Table

  ›

  Henry the Treasurer is the earliest known official of what would eventually become HM Treasury. He served under the Norman administration that arrived after the 1066 Conquest, and he likely participated in the twice-yearly gatherings known as the Exchequer, held at Easter and Michaelmas. The name itself came from something almost comically mundane: the chequered cloth spread over the counting table where royal revenues were tallied.

  Before the Normans, Anglo-Saxon rulers were already skilled at collecting and auditing cash revenues, but they ran no distinct administrative department for it. Royal treasure was stored at Winchester, though kings like Edward the Confessor kept some wealth at his palace in Westminster. The Normans changed that. By 1154, the Exchequer had grown from a seasonal event into a permanent institution based in Westminster, with two distinct parts: the Lower Exchequer, which held the royal wealth itself, and the Upper Exchequer, formed by those twice-yearly judgment meetings.

  For centuries the system functioned, but by the 1400s the Exchequer's institutional weight had begun to erode. Edward IV took much of its administrative work into his own hands. Henry VII went further, personally checking, signing, and drafting the Crown's accounts. It took Thomas Cromwell, in the early 1500s, to reverse that trend, restoring authority to the Exchequer and creating four new departments to handle state finances. Those departments were merged with the Exchequer in 1554. The institutional architecture was taking shape, but the question of who actually controlled the money, the monarch, a treasurer, or Parliament, was far from settled.

• 3. Debt, Disgrace, and Dutch Finance

  ›

  By the late 1500s, under James I, Treasury reserves had begun draining away under mounting royal debt. Treasurer Lionel Cranfield imposed strict spending controls on the Crown in what was the first recorded attempt by a Treasurer to constrain a sovereign. His reward was impeachment on charges of corruption.

  The English Civil War in the 1640s shattered what remained of the old structure. The Exchequer collapsed entirely, and finance fell to improvised Parliamentary and Royal committees. Oliver Cromwell reopened it in 1654 but left its medieval architecture untouched. At the Stuart Restoration in 1660, a Lord Treasurer returned to the post, but Parliament had by then won a permanent stake in how the treasury operated.

  The friction became acute under Charles II. Parliament had pledged him £1.2 million per year, a figure the country's poor financial state made impossible to deliver. In 1667, without consulting Parliament, Charles replaced the Lord Treasurer with a small board of officials. He wanted, as the historical record has it, the "rougher hands of younger, more energetic men to wrest control of the country's finances." One of those men was Sir George Downing, who brought hard lessons from Dutch financial practice to England. The board ended tax farming, the arrangement by which the right to collect taxes was sold to private parties, and began collecting taxes directly. Revenue grew and the Treasury's staff expanded with it.

  Heavy spending on the Anglo-Dutch wars reversed those gains. Government debt swelled, and Charles halted all debt repayments in what became known as the Stop of the Exchequer. Trust in government finances collapsed. Parliament responded by tightening its grip on how money was spent, only to surrender that control in 1685 when it granted James II nearly £2 million a year with no restrictions attached. The Glorious Revolution of 1688 corrected course. William III was deliberately kept short of permanent income to ensure his dependence on Parliament, and the revolution gave rise to new financial tools: the Bank of England, the Land Tax, and government bonds. Treasury Secretary Henry Guy, who was simultaneously a Member of Parliament, was later disgraced for accepting a bribe. New rules barred all office-holders from sitting in the Commons, creating a formal separation between civil servants and elected representatives. By the death of Queen Anne in 1714, the Treasury operated independently of the monarch entirely.

• 4. The Birth of the Budget

  ›

  Sometime in the early 1700s, 17,000 civil servants were gathering taxes across the country on the Treasury's behalf. Parliament allowed the Treasury to manage day-to-day tax collection but rarely questioned what the government chose to spend. In 1736, a new Treasury building was commissioned, physically connected to No. 10 Downing Street via internal passageways.

  Out of this period came one of the most familiar words in public life. "Budget" originally referred to a small pouch, from the French bougette. A 1733 pamphlet depicted Sir Robert Walpole satirically as a quack doctor opening his bag of tricks. The joke embedded itself in political language, and the word shifted from meaning the container to meaning the financial plan inside it.

  By the late 1770s, King George III had accumulated considerable personal debt. Parliament responded in 1782 by raising the Civil List, the mechanism for funding the monarch's household, to £900,000. Crucially, it also demanded detailed scrutiny of Civil List accounts for the first time. The Sovereign's own expenditure was now subject to Treasury examination. That shift in 1782 marked a new phase: not just Parliament overseeing the Treasury, but the Treasury overseeing the Crown.

• 5. America, Empire, and the Cost of Empire

  ›

  In 1776, the American Declaration of Independence was signed, and some historians trace a line of responsibility back to the Treasury. At the time, the Treasury had more officers stationed in America than any other British government department. After the Seven Years' War, government debt had soared, and the pressure to extract revenue from the colonies intensified. The Treasury tightened customs enforcement, restructured pay incentives, and lowered duties in an attempt to curb smuggling.

  In 1767, Chancellor Charles Townshend introduced tax legislation that would directly ignite the rebellion. Others argue that the Treasury was one player among many, acting alongside the Board of Trade, the Privy Council, and Parliament. Whether the Treasury was the driver or a participant, its fingerprints were on the colonial policy that fractured the empire.

  Back in Britain, the 1800s saw the Treasury become what historians have called the government's hard brake. Gladstone's philosophy of economic restraint gave the Treasury's power of the purse sharp new teeth. Clashes with spending departments became routine. When the Exchequers of Great Britain and Ireland were consolidated in 1817, Parliament gained complete control over government finances and the Treasury stepped into the role of enforcer, the body that said no.

• 6. Meritocracy and Its Limits

  ›

  The Northcote-Trevelyan Report of 1854 reshaped who worked in the Treasury. Recruitment shifted toward merit and fixed pay; the old routes through royal connections were formally closed off. Stricter examinations raised the entry bar. Yet public school connections continued to matter in practice. By 1914, public school and Oxbridge graduates dominated the Treasury's ranks. The reform created a selective elite rather than dismantling exclusivity.

  During the First World War, the Treasury scrambled to stabilise the financial system: it closed the Stock Exchange, paused large swathes of payment obligations, and issued new paper money including the Bradbury note. The war also pushed a deeper ideological shift. The Gladstonian instinct for fiscal prudence gave way to Keynesian management of employment and price levels. The Treasury's purpose was changing from guardian of restraint to manager of the whole economy.

  The Second World War brought physical damage. Blitz bombing struck the Treasury building, forcing a move to 1 Horse Guards Road, the address it still occupies. The 1941 Budget was the first to incorporate national accounts, a framework that tracks an entire economy's income and output. For the first time, the Treasury held a complete picture of economic activity. In 1947, Sir Stafford Cripps transferred economic planning into the Treasury, giving it control over the budget, national accounts, and the pound simultaneously.

• 7. Power Shared, Power Lost, Power Sacked

  ›

  Between 1947 and 1968, the Treasury's reach narrowed. Parliamentary reviews from 1957 to 1958 produced the Plowden Report, which pushed for greater delegation to individual departments. A further report in 1968 judged the Treasury's remit too wide. Some of its functions passed to a newly created Civil Service Department.

  The tension between institutional scope and practical control has never fully resolved. Today the Treasury sets fiscal policy and coordinates it with the Bank of England's independently operated monetary policy. The Office for Budget Responsibility provides forecasts that accompany each Budget. The Treasury also oversees the legal framework for financial services, while supervision of firms falls to the Prudential Regulation Authority and the Financial Conduct Authority under the Financial Services and Markets Act 2000.

  In October 2022, something happened that contemporary reporting described as unprecedented in Treasury history: Chancellor Kwasi Kwarteng and Prime Minister Liz Truss sacked Permanent Secretary Sir Tom Scholar. That same month, the Treasury launched a read-only Discord server aimed at younger audiences. Only the server owner could post messages, but users could send emoji reactions and change their usernames. It quickly attracted attention online, with users filling the server with offensive emoji reactions and names carrying messages. From the Stop of the Exchequer to a Discord server flooded with middle-finger emojis: the Treasury has always found ways to generate headlines it did not plan for. From October 2022, James Bowler has served as Permanent Secretary, with Beth Russell and Jim O'Neill as its two Second Permanent Secretaries.
