In national accounting, debts are added according to those who are indebted. Household debt is the debt held by households. "National" or Public debt is the debt held by the various governmental institutions (federal government, states, cities ...). Business debt is the debt held by businesses. Financial debt is the debt held by the financial sector (from one financial institution to another). Total debt is the sum of all those debts, excluding financial debt to prevent double accounting. These various types of debt can be computed in debt/GDP ratios. Those ratios help to assess the speed of variations in the indebtness and the size of the debt due. For example the USA have a high consumer debt and a low public debt, while in eastern European countries, for example, the opposite tends to be true.

There are differences in the accounting of debt for private and public agents. If a private agent promises to pay something later, it has a debt, and this debt is enforceable by public agents. If a public body passes a law stating that it'll pay something later (a kind of promise), it keeps the right to change the law later (and not to pay). This is why, for instance, the money governments promised to pay for retirements does not show up in the public debt assessment, whereas the money private companies promised to pay for retirements do.

Securitization

Securitization occurs when a company groups together assets or receivables and sells them in units to the market through a trust. Any asset with a cash flow can be securitized. The cash flows from these receivables are used to pay the holders of these units. Companies often do this in order to remove these assets from their balance sheets and monetize an asset. Although these assets are "removed" from the balance sheet and are supposed to be the responsibility of the trust that does not end the company's involvement. Often the company maintains a special interest in the trust which is called an "interest only strip" or "first loss piece". Any payments from the trust must be made to regular investors in precedence to this interest. This protects investors from a degree of risk, making the securitization more attractive. The aforementioned brings into question whether the assets are truly off-balance-sheet given the company's exposure to losses on this interest.

Debt, inflation and the exchange rate

As noted above, debt is normally denominated in a particular monetary currency, and so changes in the valuation of that currency can change the effective size of the debt. This can happen due to inflation or deflation, so it can happen even though the borrower and the lender are using the same currency. Thus it is important to agree on standards of deferred payment in advance, so that a degree of fluctuation will also be agreed as acceptable. It is for instance common to agree to "US dollar denominated" debt.

The form of debt involved in banking accounts for a large proportion of the money in most industrialised nations. There is therefore a relationship between inflation, deflation, the money supply, and debt. The store of value represented by the entire economy of the industrialized nation, and the state's ability to levy tax on it, acts to the foreign holder of debt as a guarantee of repayment, since industrial goods are in high demand in many places worldwide.

Inflation indexed debt

Borrowing and repayment arrangements linked to inflation-indexed units of account are possible and are used in some countries. For example, the US government issues two types of inflation-indexed bonds, Treasury Inflation-Protected Securities (TIPS) and I-bonds. These are one of the safest forms of investment available, since the only major source of risk — that of inflation — is eliminated. A number of other governments issue similar bonds, and some did so for many years before the US government.

In countries with consistently high inflation, ordinary borrowings at banks may also be inflation indexed.

Debt is that which is owed; usually referencing assets owed, but the term can cover other obligations. In the case of assets, debt is a means of using future purchasing power in the present before a summation has been earned. Some companies and corporations use debt as a part of their overall corporate finance strategy.

A debt is created when a creditor agrees to lend a sum of assets to a debtor. In modern society, debt is usually granted with expected repayment; in many cases, plus interest. Historically, debt was responsible for the creation of indentured servants.

Payment

Before a debt can be made, both the debtor and the creditor must agree on the manner in which the debt will be repaid, known as the standard of deferred payment. This payment is usually denominated as a sum of money in units of currency, but can sometimes be denominated in terms of goods. Payment can be made in increments over a period of time, or all at once at the end of the loan agreement.

Types of debt

A company uses various kinds of debt to finance its operations. The various types of debt can generally be categorized into:

1. secured and unsecured debt,

2. private and public debt,

3. syndicated and bilateral debt, and

4. other types of debt that display one or more of the characteristics noted above.

A debt obligation is considered secured if creditors have recourse to the assets of the company on a proprietary basis or otherwise ahead of general claims against the company. Unsecured debt comprises financial obligations, where creditors do not have recourse to the assets of the borrower to satisfy their claims.

Private debt comprises bank-loan type obligations, whether senior or mezzanine. Public debt is a general definition covering all financial instruments that are freely tradeable on a public exchange or over the counter, with few if any restrictions.

Loan syndication is a risk management tool that allows the lead banks underwriting the debt to reduce their risk and free up lending capacity.

A basic loan is the simplest form of debt. It consists of an agreement to lend a principal sum for a fixed period of time, to be repaid by a certain date. In commercial loans interest, calculated as a percentage of the principal sum per year, will also have to be paid by that date.

In some loans, the amount actually loaned to the debtor is less than the principal sum to be repaid; the additional principal has the same economic effect as a higher interest rate (see point (mortgage)).

A syndicated loan is a loan that is granted to companies that wish to borrow more money than any single lender is prepared to risk in a single loan, usually many millions of dollars. In such a case, a syndicate of banks can each agree to put forward a portion of the principal sum.

A bond is a debt security issued by certain institutions such as companies and governments. A bond entitles the holder to repayment of the principal sum, plus interest. Bonds are issued to investors in a marketplace when an institution wishes to borrow money. Bonds have a fixed lifetime, usually a number of years; with long-term bonds, lasting over 30 years, being less common. At the end of the bond's life the money should be repaid in full. Interest may be added to the end payment, or can be paid in regular installments (known as coupons) during the life of the bond. Bonds may be traded in the bond markets, and are widely used as relatively safe investments in comparison to equity.
