The Financial Silk Road

Banking has always maintained a close relationship with commerce in general, and with trade along the Silk Road in particular. Economic historians largely agree that modern European banking was born in the two famous maritime republics of Venice and Genoa during the 12th century. The original purpose of these banks was to finance the ventures of Venetian and Genoese merchants who set sail eastward in search of valuable goods from Asia, such as textiles (especially silk) and spices. Banks have also always had a unique connection to war, including in those years, during the Crusades, as both played a role in ensuring that trade routes between Europe and Asia could remain open and safe under the control of European powers.

Those early bank activities were more than just financial loans to support trading expeditions. In both republics, institutions began to take shape that would come to define modern capitalism. Among them were the first public banks and the practice of interbank current accounts. Although Venice attempted to prohibit the latter, it would later become a hallmark of modern banking systems and eventually lead to the establishment of the first central bank in London in the 17th century. Venice and Genoa also saw the rise of specialized services like currency exchange to stabilize value and standardise purchasing power in international markets, and insurance to underwrite trade risk.

It was along the initial stretch of the Silk Road that the first international banks were born. To streamline operations and make the relationship between banks and merchants more efficient, the Venetians opened the first overseas bank branches in their small but strategically vital colony within the city of Constantinople. This Venetian banking presence effectively turned Constantinople into the world’s first proto-modern international financial centre, with its rise directly linked to Silk Road trade activities.

We know of these banks through various historical accounts. One such report tells how a Venetian bank’s branch in Constantinople was attacked by the Genoese in 1261 in retaliation for their earlier defeat at Acre in 1258. The Genoese struck at the heart of Venetian economic power in the East. In a symbolic move, they literally dismantled the bank building and transported the stones back to Genoa.

From these early stirrings of the modern economy, banking activity and economic conflict have evolved at a remarkable pace. Commercial powers have always expanded economically through the growth of their banking networks. Over time, banks, particularly British ones, established a presence in other parts of the world as well. Think, for instance, of the early colonies in North America, whose banks and their financial independence would become a major point of tension with the British Crown. Meanwhile, European powers continued to push banking networks deeper into the Silk Roads.

In 1865, for example, a Scottish employee of a Hong Kong–based shipping company, Thomas Sutherland, came up with the idea of founding a bank locally to facilitate trade between Britain and China. This gave rise to HSBC, which today is one of the world’s largest international banks and a key player in offshore Chinese currency business. A few decades later, German banks began expanding into Egypt, Persia, and other parts of the Middle East. Their expansion accompanied major infrastructure projects, such as the Berlin–Baghdad railway, which aimed to secure vital strategic ties with oil-producing regions.

Some trace the origins of banking and commerce in the eastern Mediterranean back even further, to the enterprises of the Phoenicians. Yet, despite enormous technological advances, the fundamental mechanics of global banking have remained surprisingly consistent over time. What is new today is the emergence of China’s expansion strategy, which involves spreading its banking networks along the Silk Roads across Eurasia, and increasingly into Europe. This development has become one of the defining features of 21st-century potential global economic cooperation, but also the cause of growing geopolitical tensions. This is a central theme of the Financial Silk Road, which we will explore in depth along the way.
