Globalisation since 1870 has not been a steady march towards more trade and freer movement of money. It has advanced, broken down and returned under different rules. The broad sequence runs from nineteenth century integration through wartime disruption, postwar reconstruction and the expansion of international production and finance. The IMF’s historical overview of globalisation distinguishes these phases rather than treating integration as an irreversible trend.

The central distinction is between moving goods and moving capital. A country can welcome imported machinery while restricting foreign borrowing. It can also attract overseas money without becoming a major exporter. Within the broader study of economic history, separating those activities helps explain why trade, investment and financial crises do not always follow the same timetable.

What Trade and Capital Flows Measure

International trade records exchanges of goods and services. Capital flows concern financing and ownership across borders. Buying imported equipment is a trade transaction; borrowing from a foreign bank to pay for it creates a financial relationship. The two can support each other, but they are not interchangeable.

Three distinctions make historical comparisons more useful:

• Direct investment: establishing or acquiring a lasting business interest abroad, such as a factory or subsidiary.
• Portfolio investment: buying securities, such as foreign government bonds or company shares, without taking a controlling business role.
• Bank lending and other credit: providing finance that may fund trade, property, business expansion or financial transactions.

Flows also differ from stocks. A flow measures investment during a period; a stock measures the accumulated position at a point in time. Neither automatically measures new productive capacity. Buying an existing factory changes its ownership, whereas building another factory adds capacity. Both can appear within international investment activity.

Consider a hypothetical manufacturer buying a foreign plant for $100 million. That transaction tells us something about ownership and financing. It does not, by itself, tell us whether employment, output or exports will rise. Those require separate evidence.

1870–1914: The First Modern Wave of Globalisation

The decades before the First World War combined expanding trade with substantial overseas investment. European economies supplied much of the finance, with Britain the leading investor and London a major centre for arranging international borrowing. Railway development, government debt and raw materials attracted a large share of British portfolio investment. Bonds mattered more than an image of investors buying shares in overseas factories might suggest.

This was not yet the international production system familiar from modern manufacturing. Overseas investment often financed transport infrastructure and access to resources rather than dividing one production process among several countries. The French Treasury’s study of trade and finance during the first globalisation draws that distinction between the two eras.

A hypothetical railway loan shows how trade and capital could reinforce each other. Overseas investors provide the money for construction. The railway then reduces the cost of bringing crops or minerals to a port. Export earnings help the borrower service its debt. The arrangement works only if traffic, prices and revenues justify the original borrowing.

Currency arrangements also mattered. The gold standard forms a separate part of this history: exchange rate commitments could reduce one source of uncertainty without removing commercial or default risk. A predictable currency conversion was no guarantee that a railway would carry enough freight.

Empire Shaped Who Traded With Whom

Early globalisation did not take place among countries with equal political power. Imperial relationships shaped commercial connections through preferential trading arrangements, currencies, customs systems and shared administrative languages. These channels are examined in the NBER research paper Trade and Empire.

That distinction changes how the period should be assessed. Higher trade volumes are evidence of stronger commercial connections, not proof that all participants gained on equal terms. The relevant questions include who controlled market access, who received investment income and whether producers could choose alternative buyers.

The same caution applies to infrastructure. A railway can lower transport costs while serving a narrow export route rather than the wider domestic economy. Measuring the miles of track is easier than judging how its benefits were distributed, but both questions belong in an account of globalisation.

1914–1945: Integration Goes Into Reverse

The First World War interrupted the earlier international order. Attempts to restore monetary stability during the 1920s did not repair every underlying imbalance. The return to gold was followed by renewed financial strain, and the 1929 US stock market crash accelerated the withdrawal of American capital from abroad.

During the Depression, governments tried to protect domestic activity through trade restrictions and other measures that shifted pressure onto trading partners. When many countries pursued that approach together, international commerce contracted further. The IMF’s account of the interwar monetary breakdown connects the retreat of foreign lending with the deterioration in trade.

The practical problem was circular. A borrower losing access to overseas finance had to cut spending or find another source of funds. Falling spending reduced demand for imports. Exporters elsewhere then lost revenue, making their own debts harder to service.

This is why the period cannot be reduced to a single tariff or stock market event. Trade barriers, collapsing demand, fragile credit and monetary constraints interacted. The broader lesson is that commercial connections depend on institutions and political choices, not just the physical ability to ship goods.

1944–1973: Rebuilding Trade With Managed Finance

The monetary arrangements designed at Bretton Woods in July 1944 sought greater exchange rate stability after the interwar breakdown. Participating currencies were pegged to the dollar, while the United States maintained an official gold price of $35 an ounce. The system did not require unrestricted movement of private capital.

Indeed, the United States itself later restricted overseas direct investment and bank lending to address payments pressures. This is a useful corrective to the idea that postwar openness meant removing every financial barrier. The Federal Reserve’s history of the Bretton Woods system also traces its ending: the United States closed the gold window in August 1971, and major currencies moved to floating rates in March 1973.

The policy distinction was straightforward, even if implementation was not. Governments could support payments for international commerce while trying to restrain financial movements that threatened their exchange rate commitments.

Think of a manufacturer importing machinery under a managed currency system. Its payment supports a commercial purchase. A rapid transfer of financial wealth abroad has a different purpose and can place different pressure on the exchange rate. Treating both transactions identically was not the only available policy choice.

From Postwar Recovery to Wider Market Opening

Trade expanded strongly after the Second World War. Real merchandise exports grew by more than 8% annually between 1950 and 1973, with Western Europe and Japan prominent in the expansion. The General Agreement on Tariffs and Trade, established in 1947 and effective from January 1948, provided a framework for negotiated trade opening.

Later changes widened participation. China began economic reforms in 1978, India launched reforms in 1991, and the dissolution of the Soviet Union changed established trading relationships. The WTO began operating in 1995, and China joined in 2001. These milestones appear in the WTO’s historical analysis of globalisation and trade.

Those dates should not be mistaken for instant transformations. Signing an agreement does not produce a port, a reliable electricity supply or a network of capable suppliers overnight. Market access creates opportunities; businesses still need the capacity to use them.

Nor should floating exchange rates be treated as synonymous with financial liberalisation. One concerns how a currency’s price is determined. The other concerns which transactions governments permit. They can change at different speeds, with different consequences for exporters, borrowers and investors.

1990s–2008: Production Crosses More Borders

A major change in modern globalisation was the growth of global value chains: production arrangements in which different stages take place in different countries. Rather than exporting only a finished product, businesses could supply components, assembly, design or business services within a wider production network.

These networks powered much of the trade expansion after 1990. The World Bank’s World Development Report 2020 estimated that global value chains accounted for almost half of global trade at the time of publication. It also found that their expansion had stalled following the 2008 financial crisis.

A hypothetical appliance illustrates the difference. Its motor comes from one country, its electronic controls from another, and final assembly happens in a third. The finished appliance is then sold elsewhere. Several border crossings contribute to recorded trade, even though the customer buys one product.

This creates opportunities to specialise without building an entire industry from scratch. It also changes exposure to disruption. A supplier does not need to account for much of the final selling price to hold up production. A missing inexpensive component can stop an expensive assembly line; accounting importance and operational importance are different things.

Financial Globalisation Became More Than Trade Finance

International finance also expanded beyond lending directly connected to goods and production. Banks, companies and investors accumulated foreign assets and liabilities for financial purposes. From the late 1980s, financial openness increased faster than trade openness, especially among advanced economies. The BIS analysis of financial and economic globalisation distinguishes these financial connections from trade and production networks.

This makes gross positions as important as net balances. Suppose residents acquire $100 billion of foreign assets while foreigners acquire $95 billion of domestic assets. Net outward investment is only $5 billion, but the transactions create much larger claims in both directions.

The distinction matters during a funding shock. A country with a modest net position can still contain institutions that owe large amounts in a foreign currency or depend on lenders renewing short term credit. Aggregate balance is not the same as safety for every borrower.

For the banking failures and policy responses, the separate history of the global financial crisis of 2007–2009 covers the event itself. Here, the relevant issue is transmission: financial relationships can connect economies even where their direct trade with each other is small.

Since 2008: Slower Integration and Greater Political Friction

The post-crisis period has raised a different question: is globalisation shrinking, or changing its shape? The COVID-19 pandemic, the war in Ukraine and geopolitical tensions intensified debate over supply security. Reshoring means bringing activity home; nearshoring places it closer to a market; friendshoring favours politically aligned partners.

These strategies are not equivalent to ending international trade. Production may move between foreign countries rather than return home. The WTO’s World Trade Report 2023 identified early signs of fragmentation while cautioning against interpreting a flatter trade-to-GDP ratio as a simple reversal of trade integration.

There is a genuine decision to make between cost and resilience. A business might accept higher purchasing costs to avoid depending on one supplier. But replacing several overseas suppliers with one domestic producer could create a different concentration risk. Location alone does not settle the issue.

Investment data likewise resist a simple story of continuous retreat. Global foreign direct investment rose 6% to $1.6 trillion in 2025, ending two years of decline, although the recovery was uneven. That result is reported in UNCTAD’s 2026 assessment of international investment. A rising total still requires closer examination of its destinations and uses.

What the History Changes About the Debate

The most useful question is not whether an economy is “globalised” in a simple yes-or-no sense. Ask which connections are expanding: finished goods, intermediate inputs, services, business ownership or debt. Then ask who depends on whom, in which currency, and for how long.

That approach avoids two easy mistakes. More trade does not guarantee that every community benefits, and more foreign capital does not guarantee productive investment. Equally, reducing an international connection does not automatically remove its associated risk. It may transfer that risk elsewhere.

Since 1870, the recurring issue has been how to obtain the benefits of international exchange without assuming that its financing, political support or distribution of gains will take care of themselves.
