Fourth Quarter 2006 

 Debt of the domestic nonfinancial sectors 

expanded at a seasonally adjusted annual rate of 8 

percent in the fourth quarter of 2006. Debt growth in 

the fourth quarter was faster than the third-quarter pace, 

as slower debt growth in the household sector was more 

than offset by faster growth for nonfinancial businesses 

and state and local governments. Domestic 

nonfinancial debt rose 8 percent over 2006 as a whole, 

about 1-1/2 percentage points slower than in 2005. 

 Household debt expanded at an annual rate of 

6-1/2 percent in the fourth quarter of 2006, about 1 

percentage point below the pace in the third quarter. 

Last quarter, growth of home mortgage debt decreased 

to a rate of 6-1/2 percent—the slowest quarterly pace 

since 1998—and consumer credit rose at a rate of 4-1/2 

percent. For 2006 as a whole, household debt increased 

8-1/2 percent, about 3 percentage points less than in 

2005. The deceleration of household debt last year was 

accounted for by much slower growth of home 

mortgage debt. 

 Nonfinancial business debt rose at an annual 

rate of 11 percent in the fourth quarter of 2006, much 

faster than in the third quarter. Large increases in the 

net issuance of open market paper and corporate bonds 

contributed to the pickup in debt growth last quarter. 

At the same time, nonfinancial corporations, on net, 

retired a large volume of equity shares. The 9 percent 

expansion of nonfinancial business debt over all of

2006 was nearly 2 percentage points faster than in 

2005. 

 State and local government debt increased at 

an annual rate of 13-1/2 percent last quarter, and 

expanded 8-1/4 percent over all of 2006. Federal 

government debt rose at a pace of 3-1/4 percent in 

fourth quarter of last year, and increased 4 percent for 

the year as a whole. In 2006, growth of federal 

government debt averaged its slowest pace since 2001. 

 At the end of 2006, the level of domestic 

nonfinancial debt outstanding was $28.7 trillion. 

Household debt amounted to $12.8 trillion, and 

nonfinancial business debt was $9.0 trillion. 

Combined, state and local governments and the federal 

government had outstanding debt of $6.9 trillion. 

 Household net worth—the difference between 

the value of assets and liabilities—amounted to 

$55.6 trillion at the end of the fourth quarter of 2006. 

Household net worth rose $1.4 trillion dollars last

quarter, with most of that increase accounted for by 

gains on direct and indirect holdings of corporate 

equity.

Flow of Funds Accounts, Fourth Quarter 2006 

This publication presents the flow of funds 

accounts for 2006:Q4. 

Data revisions and other changes. The statistics in 

the attached tables reflect the use of new or revised 

source data. Most significant revisions appear in recent 

quarters; however, new source information resulted in 

changes to data for earlier periods. 

1. Assets of the nonfarm nonfinancial corporate 

business sector (tables F.102 and L.102) were revised 

from 2004:Q1 onward to reflect final data from the 

Internal Revenue Service (IRS) Statistics of Income

(SOI) for 2004. 

 

2. In the nonfarm noncorporate business sector 

(tables F.103 and L.103), data have been revised from 

2004:Q1 onward, owing to benchmark statistics 

available from the IRS/SOI for 2004. 

3. Due to a reclassification of some savings 

institutions into the commercial banking sector in 

2006:Q4, the U.S.-Chartered Commercial Banks sector

(table F.110) reports larger than usual positive flows in 

certain instrument categories last quarter, while the 

Savings Institutions sector (table F.114) reports some 

larger than usual negative flows. The asset category 

most affected by these reclassifications is mortgages; 

the liability categories most affected are time and

savings deposits and other loans and advances. 

Explanatory notes for tables D.1, D.2, and D.3. 

Domestic debt comprises credit market funds borrowed 

by U.S. entities from both domestic and foreign 

sources, while foreign debt represents amounts 

borrowed by foreign financial and nonfinancial entities 

in U.S. markets only. Financial sectors consist of 

government-sponsored enterprises, agency- and GSEbacked mortgage pools, and private financial 

institutions. Credit market debt consists of debt 

securities, mortgages, bank loans, commercial paper, 

consumer credit, U.S. government loans, and other 

loans and advances; it excludes trade debt, loans for the 

purpose of carrying securities, and funds raised from 

equity sources. 

 Growth rates in table D.1 are calculated by 

dividing seasonally adjusted flows from table D.2 by 

seasonally adjusted levels at the end of the previous 

period from table D.3. Seasonally adjusted levels in 

flow of funds statistics are derived by carrying forward 

year-end levels by seasonally adjusted flows. Growth 

rates calculated from changes in unadjusted levels 

printed in table L.2 can differ from those in table D.1. 

Relation of Flows to Outstandings. Estimates of 

financial assets and liabilities outstanding are linked to 

data on flows. However, figures on outstandings 

contain discontinuities or breaks in series that could 

affect analysis of particular relationships over time 

specifically, outstanding in the flow of funds accounts 

are related to the flows in the following way: 

Outstanding B

t

B = Outstanding B

t-1B+ Flow Bt

B+ Discontinuity B

t

B 

where “t” is the time period. 

 Discontinuities result from changes in 

valuation, breaks in source data, and changes in 

definitions. For most series, the value of the 

discontinuity is zero for nearly all time periods. 

However, in a few instances, the discontinuity is 

nonzero for almost all time periods, or is quite large in a 

particular quarter, such as a period when there is a 

sharp increase or decrease in equity prices or a major 

break in source data. 

 The discontinuities in a series can distort 

estimated rates of growth in assets and liabilities

between periods. In order to minimize these 

distortions, percentage changes in assets and liabilities 

in flow of funds releases should be calculated as: 

Percentage change B

t

B = (Flow B

t

B / Outstanding B

t-1B) * 100 

Preliminary Estimates. Figures shown for the most 

recent quarter in these tables are based on preliminary 

and incomplete information. A summary list of the 

principal sources of information available when the 

latest quarter's data were compiled is provided in a table 

following this introduction. The distinction between 

“available” data and “missing” data is not between final 

and preliminary versions of data, but rather between 

those source estimates that are fully ready when the 

latest quarterly publication is compiled and those that 

are not yet completed. However, the items that are

shown as available are, in general, also preliminary in 

the sense that they are subject to revision by source 

agencies. 

1
Margins of Uncertainty. Flow of funds statistics are 

subject to uncertainties resulting from measurement

errors in source data, incompatibilities among data from 

different sources, potential revisions in both financial 

and nonfinancial series, and incomplete data in parts of 

the accounts. The size of these uncertainties cannot be 

quantified in precise statistical terms, but allowance for 

them is explicitly made throughout the accounts by the 

inclusion of “discrepancies” for various sectors and 

instrument types. A discrepancy for a sector is the 

difference between its measured sources of funds and 

its measured uses of funds. For an instrument category, 

a discrepancy is the difference between measured funds 

borrowed through the financial instrument and 

measured funds lent through that instrument. The size 

of such discrepancies relative to the main asset or

liability components is one indication of the quality of 

source data, especially on an annual basis. For 

quarterly data, differences in seasonal adjustment 

procedures for financial and nonfinancial components 

of the accounts sometimes result in discrepancies that 

cancel in annual data. 

Availability of Data. Flow of funds statistics are 

updated about ten weeks following the end of a quarter. 

This publication — the Z.1 release — is available from 

the Board's Publications Services. Flow of funds data 

are also available electronically through the Internet at 

the following location: 

http://www.federalreserve.gov/releases/Z1

 

 

 The Internet site also provides quarterly data 

beginning in 1952, organized in compressed files that 

correspond to the tables published in this release. 

There are files for quarterly data for seasonally adjusted 

flows, unadjusted flows, outstandings, balance sheets, 

and debt (tables D.1, D.2, and D.3). 

 A Guide to the Flow of Funds Accounts 

is available. The 1,200-page Guide, published in two 

volumes in January 2000, explains in detail how the

U.S. financial accounts are prepared and the principles 

underlying the accounts. The Guide can be purchased 

for $20.00 from the Board’s Publications Services. 

Publications Services accepts orders accompanied by

checks as well as credit card orders. 

 The Internet site for this release at the location

shown above contains a link to an order form for the 

Guide that can be mailed or faxed to Publications 

Services. In addition, the Internet site includes a link to 

the Guide’s descriptions of the tables in the flow of 

funds accounts.
