A merchant should never lend merely because he has money available.
Money placed in a loan becomes a claim upon another man, family, city, prince, revenue stream, or pool of property. The apparent simplicity of the transaction conceals this dependence.
The young merchant looks first at the promised return. The experienced merchant asks what must happen for principal and profit actually to come back.
Lending can be safer than trade, but it can also be more deceptive. Goods may fall in price, yet they remain goods. A debtor’s promise may be written for a large amount and still become almost worthless if the man cannot or will not pay.
The first rule is therefore simple: never judge a loan by the interest alone. Judge the debtor, the purpose, the term, the security, the source of repayment, and the difficulty of collection.
13.1 When Lending Is Better Than Trading
There are times when the House should own merchandise and times when it should finance others who own it.
Lend when our advantage lies in capital: Another merchant may understand wool, grain, or cloth better than we do, while our House possesses stronger liquidity and cheaper access to funds. If he can employ money profitably and offers adequate return and protection, lending may be wiser than entering a trade we understand poorly.
Lend when merchandise is unattractive: Goods may be expensive, markets uncertain, freight dangerous, or warehouses already full. Capital need not be forced into merchandise merely because trade is our ordinary occupation.
A sound loan may preserve earning power while we wait for better opportunities.
Lend when turnover is clearer: A loan with a known maturity can sometimes return capital more predictably than goods whose sale date is uncertain.
This advantage disappears if the debtor cannot pay when maturity arrives.
Lend when risk is easier to define: A well-secured advance against sound merchandise already sold to reliable buyers may be easier to judge than taking ownership of a speculative cargo.
But remember that security must be real, not merely described as real.
Do not lend because trading requires more work: Merchants who tire of inspection, shipping, customers, and warehouses sometimes convince themselves that lending is the simpler business.
It is simpler only until collection becomes difficult.
Compare returns honestly: A loan yielding eight percent for six months should be compared with what the same capital could earn elsewhere during the same period, allowing for risk, liquidity, and effort.
Do not compare a certain loan return with the best imaginable result from a speculative trade, nor compare a risky loan with the ordinary profit of safe merchandise.
Consider liquidity: A long loan reduces the House’s freedom. If the House expects heavy maturities or political disturbance, a modest short loan may be preferable to a high-return advance for several years.
Keep lending within the House’s competence: Lending to merchants whose businesses we understand is often safer than lending into unfamiliar activities. Knowledge of the underlying trade improves judgment about repayment.
A lender who does not understand the debtor’s business is partly blind.
13.2 Loans to Merchants, Nobles, Cities, and Princes
Not all debtors should be judged alike. A merchant, nobleman, city, and prince may each owe the same sum while presenting entirely different risks.
Merchants: Loans to merchants should be judged from the trade producing repayment.
Ask what the money will finance, how quickly that activity turns, what other debts exist, whether the merchant’s accounts are orderly, and what happens if the intended transaction fails.
A short advance to finance goods already contracted for sale differs greatly from money used to cover old losses.
If a borrower cannot explain clearly why he needs the funds, do not explain it for him.
Nobles: Noble borrowers may possess extensive property but little ready cash. Land, titles, rents, and estates create an appearance of security that can mislead a merchant.
Ask what income actually reaches the borrower, what property is already encumbered, what claims family settlements or dowries have upon it, and whether a creditor can practically enforce against it.
A palace is impressive until one attempts to collect a commercial debt from its stones.
Cities: Municipal loans may be supported by customs, excises, taxes, tolls, or designated revenues. Their safety depends upon the reliability of those revenues, existing claims against them, legal arrangements, and the city’s willingness to honor creditors.
Examine whether the assigned income has already been promised elsewhere. A revenue stream pledged three times provides less comfort than the documents suggest.
Princes and sovereigns: Lending to rulers can be highly profitable and highly dangerous.
A prince may command taxes, customs, mines, offices, and territories. He may also change the terms under which creditors are repaid.
Never reason that a ruler must be safe because his resources exceed those of any merchant. The relevant question is whether those resources will be made available to us when payment is due.
Purpose matters: Financing a known tax collection, military supply contract, or identified revenue may be more intelligible than providing money for unspecified “needs of the Crown.”
The clearer the source of repayment, the better the judgment.
Political dependence: A large sovereign loan can make the House financially dependent upon the policies of one court. If the same prince also influences our trading privileges, ships, or other receivables, the concentration becomes greater still.
Count all exposures together.
Syndication and participation: Where a loan is too large for prudent concentration, divide it among several financiers or participate only for a fraction.
The fact that a borrower desires 500,000 lire does not require our House to provide 500,000.
Participation reduces exposure, though it introduces questions about who negotiates, holds security, collects, and represents the lenders.
Translator note: Large early modern financings were often shared among several merchant-bankers rather than carried entirely by one house. This reduced individual exposure while allowing substantial sums to be advanced to governments, cities, and major commercial borrowers.
13.3 Security, Guarantees, Pledges, and Assignments of Revenue
A promise to repay is strongest when both willingness and means support it. Security provides additional protection when either becomes uncertain.
Security: Before accepting any asset as security, ask who owns it, what it is worth in unfavorable conditions, whether another creditor has prior claim, how easily it can be sold, and whether we can actually take possession if default occurs.
Security that cannot be reached is decoration.
Pledged goods: Merchandise may be pledged as collateral. Inspect quantity, quality, location, title, and marketability.
If the debtor retains full physical control, he may sell, move, substitute, or pledge the same goods again. Control matters as much as description.
Value conservatively: Goods worth 100 in a good market may be worth 60 when the borrower fails, because borrowers often fail during poor markets.
Collateral should be valued for the day on which we may need to sell it, not the day on which we are eager to make the loan.
Immovable property: Land and buildings may provide substantial value, but collection can be slow, legally complicated, and politically sensitive.
Determine title, existing mortgages or claims, expected income, and whether the property can be transferred or sold to satisfy us.
Guarantees: A guarantor promises to answer if the principal debtor does not. Judge the guarantor as though he might become the borrower tomorrow.
Do not accept the signature of a prestigious man without examining whether his assets and obligations actually support the amount.
Several guarantors: Multiple guarantors can strengthen a loan if they are independently strong. They add little if all depend upon the same business or family fortune.
Assignment of revenue: A borrower may assign customs receipts, rents, taxes, contract payments, or other income to the lender.
This can be powerful protection when the revenue is stable and the assignment enforceable.
Ask who collects the revenue, whether it passes directly to us, what expenses or senior claims are deducted first, and whether the borrower can redirect it.
Possession and documentation: Important pledges, guarantees, and assignments should be documented precisely. If originals, warehouse receipts, titles, or other instruments establish rights, secure them.
Where appropriate, formalize the arrangement before a notary (notaio).
Do not let security replace judgment: A poor debtor with excellent security may be acceptable in some cases, but only if the House is genuinely willing and able to enforce the security.
If we know we would never seize the duke’s estate because political consequences would be intolerable, do not pretend the estate protects us fully.
13.4 Pricing a Loan for Risk, Term, and Difficulty of Collection
The price of money should reflect more than time.
Risk: The greater the probability of loss, the greater the return required. But there is a point beyond which a higher rate does not make a bad loan good.
A loan expected to lose principal cannot be repaired merely by charging more interest.
Term: Money committed for a year should generally earn more than money committed for a month because the House surrenders liquidity longer and faces more time in which circumstances may change.
Security: Strong, liquid, well-controlled collateral may justify a lower return because expected loss is reduced.
Weak or difficult security should be priced accordingly—or rejected.
Collection difficulty: Two borrowers of equal financial strength may deserve different terms if one pays voluntarily while the other requires continual pursuit, legal expense, favors, travel, or political negotiation.
Collection effort is part of the cost of the loan.
Currency and place: Repayment in a foreign city or currency creates exchange risk and remittance cost. State the place and money of payment clearly and consider both in the price.
Fees and commissions: Some arrangements include commissions, exchange differences, fees, or other forms of compensation in addition to the stated return.
Judge the entire economic result rather than one named rate.
Renewal risk: A borrower may ask for a short loan while both sides privately expect continual renewal. If the House is unlikely to recover its money at the first maturity, price and judge the transaction according to the probable true duration.
Opportunity cost: Lending 100,000 lire to one borrower prevents that money from being used elsewhere. Compare the proposed return with other available uses of capital.
Legal and moral form: Lending practices are shaped by law, custom, and religious restrictions, and commercial arrangements may take forms more complex than a simple stated interest-bearing loan.
Use competent legal and notarial advice where form matters. Do not disguise a transaction so cleverly that nobody later understands the rights created.
Translator note: Early modern European credit operated within legal and religious restrictions on usury, yet merchants employed a wide range of legitimate instruments involving exchange, partnership, annuities, assignments, and commercial credit. The economic return must therefore be understood from the whole arrangement rather than from a single stated “interest rate.”
The proper return is the one that compensates the House for capital employed, time surrendered, risk borne, work required, and alternatives refused.
13.5 Never Confusing a Powerful Debtor with a Safe Debtor
The most dangerous borrower is often not the poorest.
It is the man everyone assumes cannot fail.
Power can weaken collection: A ruler, great noble, or politically protected merchant may possess vast resources while remaining difficult to compel.
A small merchant fears losing his credit. A prince may decide that creditors must wait.
Promises of influence are not repayment: Powerful debtors may offer licenses, introductions, monopolies, offices, or future favors when cash is unavailable.
Such benefits may have value, but value them separately. Do not allow an unpaid debt to disappear beneath gratitude for political access.
Watch concentration: A House that finances one court heavily may gradually organize its whole business around that relationship. Loans, tax contracts, exchange, privileges, and other activities become connected.
The apparent diversity is false if one political decision can damage all of them.
Do not follow the crowd: When many respected Houses lend to one borrower, each may assume the others have investigated more carefully.
Sometimes everyone is relying upon everyone else.
Conduct our own judgment.
Renegotiation: Powerful borrowers frequently request extensions rather than openly default. An extension may be sensible if it improves recovery, but call it what it is: the original terms were not met.
Do not record a troubled loan as healthy merely because new paper replaces old paper.
Reduce when possible: If payments arrive, use them to reduce exposure rather than immediately lending the money back simply to preserve favor.
The best moment to reduce dependence upon a great debtor is when he still wishes to borrow from us.
Preserve alternatives: Political influence purchased through credit becomes dangerous when the House believes it cannot survive without the borrower’s favor.
Maintain other markets, counterparties, and sources of profit.
Know the source of repayment: Before every important loan ask one final question: from what exact source will the money returning to us come?
Not “from his fortune.” Not “from the city.” Not “from the Crown.”
Which sale, tax, rent, customs revenue, receivable, estate income, or other identifiable source will produce the funds?
If the answer is vague before the loan, it will usually be vague at maturity.
My sons, lending is not the business of believing promises. It is the business of judging promises.
Use loans where they offer a better combination of return, safety, and liquidity than trade. Judge merchants by their businesses, nobles by their accessible income and property, cities by their revenues and obligations, and princes by both their resources and their willingness to honor creditors.
Take security when it improves recovery, but verify ownership, value, priority, and control. Value collateral for bad conditions, because that is when it will matter.
Price money for time, risk, collection difficulty, currency, and opportunity cost. Do not increase the rate until an unsafe loan merely appears profitable.
Above all, never confuse importance with creditworthiness.
A debtor may command armies and still be a poor payer.
A modest merchant may command little beyond his counting house and yet be one of the safest men to whom we can lend.
Power tells us what a man can influence.
Credit tells us whether our money will come back.
Do not confuse the two.
