Venetian Coinage, Banking and Payments

The Republic of Venice, centered on a lagoon city in northern Italy, was governed by a doge, its chief magistrate. Venetian payments combined metal coins with account units and ledger entries. In Rialto, the city’s commercial district, private and public banks converted deposits into recorded transfers; the Republic also borrowed money to meet the cost of war.

Coins and units of account

About 1194, Doge Enrico Dandolo’s government introduced the silver grosso, a larger and finer coin suited to substantial payments. Venice began striking its gold ducat in 1285, at about 3.56 grams and very high purity. The ducat became a familiar coin in Mediterranean trade, while the silver grosso remained central to high-value accounting and exchange.

The relationship between the two metals could shift as gold and silver changed in market value. Venice set an official rate of one ducat to 24 grossi in 1328, but by the sixteenth century the grosso was no longer being paid as a circulating coin. The lira di grossi and its subdivisions survived as units for recording large sums. For smaller values, accounts used the lira di piccoli, divided into 20 soldi or 240 denari. A bookkeeper could therefore record a debt in a lira or ducat without requiring a matching coin to change hands.

The gold coin itself also separated from a ducat used in accounts. By the sixteenth century the actual gold piece was commonly called a zecchino, while a “current ducat” could mean an accounting value fixed at six lire and four soldi. This gave merchants and officials a consistent way to compare payments even as circulating coin values moved.

Payment across the republic

In twelfth-century mainland trade, Venetian merchants sometimes used locally current units, as Louise Buenger Robbert notes. The practice shows merchants adapting accounts to the currency used where each transaction took place. Later Venetian expansion brought these commercial relationships into new political settings.

Venice’s monetary practice also varied by location. In the early thirteenth-century Venetian territory in the Greek-speaking eastern Mediterranean, called Romània, private and official payments were recorded in the Byzantine hyperperon, a gold coin and accounting standard. The duke of Crete, his officers and Venetian residents there collected revenues in hyperpera. Using a local unit made the accounts workable in a region where Venetian coins were not the only currency in circulation.

At Rialto, merchants faced another problem: Venetian and foreign gold, silver and copper coins circulated together, and some were underweight. Private deposit banks, known as banchi di scritta, accepted a merchant’s money and recorded a balance in their books. The merchant or an agent could instruct the banker to transfer part of that balance to another customer. The receiving merchant gained a credit in the ledger, so a payment could be settled without carrying a large quantity of coin across the market.

Bankers also expressed different currencies through a shared “bank ducat,” an account unit used to compare their values. The system could fail when a banker invested deposits and customers sought their money at once. After the Pisani–Tiepolo bank collapsed in 1584, the Senate barred new private banks and moved to a state-guaranteed service.

Public banks and commercial credit

In 1587 the Senate created the Banco della Piazza di Rialto. It accepted deposits and transferred balances between accounts, as the private banks had done, but the state guaranteed its operation and oversaw the value of the coins handled there. From 1593, the Senate required bills of exchange, written orders directing payment to another party, to be settled through the bank. Deposits there reached 1.7 million ducats in 1618.

The Banco del Giro, established in 1619, served a different purpose at first: it recorded money the state owed to suppliers. In June, the Flemish merchant Pietro Vogher asked for 12,000 ducats of his 25,000-ducat credit for copper deliveries to be entered in the bank. That entry made a government obligation usable as a transferable credit. The Giro later accepted private deposits as the Rialto bank declined; the Rialto bank closed in 1637.

Loans financed the republic

Public borrowing was separate from money deposited in a merchant’s bank account. In some periods, Venice required direct taxes such as the decima and tansa to be paid as loans, with annual interest due until the state repaid the principal. During the Ottoman war of 1537–1540, the government increasingly sought voluntary loans through deposits at the Mint, or Zecca. In 1537 it authorized deposits totaling 124,000 ducats at six percent interest; as wartime needs rose, the rate increased to 7.5 percent and then eight percent.

Depositors held an interest-bearing claim on the state, while bank customers held a payable balance or transfer credit. The distinction mattered: the Mint’s deposits helped finance public expenditure, whereas the Banco della Piazza and Banco del Giro handled payments and commercial credits through their ledgers.
