The Direction of Debt
What rising federal debt, inflation, and interest rates mean for your household – and what’s in your control.
Why should a household care about federal debt, a Federal Reserve meeting, or an oil disruption thousands of miles away? Because debt, inflation, interest rates, and economic growth are connected. A change in one can eventually affect government spending, business investment, mortgage rates, investment values, and household purchasing power.
Large numbers are difficult to evaluate by themselves. Federal debt, household debt, government revenue, and taxes all tend to rise over time as the economy and population grow. Gross domestic product, or GDP, measures the value of the goods and services produced by the economy. Comparing debt or revenue with GDP gives us a common measuring stick and helps show whether it is growing faster or slower than the economy supporting it.
GDP does not measure everything that makes a country or household prosperous. But it provides valuable context for understanding the size of debt, revenue, and spending relative to the economy. That is why many of the charts in this article compare other figures with GDP.
This article follows those connections. We will look at how debt has shifted among households, businesses, and the federal government; why the cost of carrying that debt matters; how inflation affects interest-rate decisions; and how events such as the war with Iran can eventually reach an American household.
The objective is to provide enough historical context that the next time you hear about inflation, interest rates, or federal debt, you have a framework for understanding what the numbers may mean.
The Supply and Direction of Debt
“Debt can fuel growth. Too much debt can be reckless and catastrophic.”
In the mid-2000s household net worth grew, most notably home values. In a concerted strategy to lift us out of the recession in the early 2000s, households were encouraged to borrow and spend. We were introduced to 0% interest rates and high tolerance to leverage home equity. The expansion of household debt fueled an economic recovery as people borrowed massive amounts from their homes and used that money to spend on other projects. Debt was a multiplier on household economies, allowing people to spend a much greater amount than their income supported. It was not sustainable. Situations collapsed, and we spiraled into a global recession known as the Financial Crisis of 2008. Many households went bankrupt and lost their homes.
Household Debt, Federal Debt, and Corporate Debt as a Percentage of GDP
“Household debt went from 70% of GDP in the year 2000 to 102% in 2007.”
The Financial Crisis of 2008 exposed the household overleverage. The result was massive bankruptcy, foreclosures, and a huge hit to personal balance sheets. Since then, households have been reducing their dependence on debt and building on their investments. Meanwhile, the federal government ramped up its leverage in response to the recession and increased debt again during COVID.
“Federal debt went from 64% of GDP in 2007 to 125% in 2025.”
We had three major expansions of debt relative to GDP since 1980. One began in the early 80s and lasted through 1991. The second began in 2000 and continued through 2009. The third was shorter, an acute response to COVID in 2020 and 2021.
“Simplistically speaking, government debt is a historical collection of deficits.”
This chart shows federal income with additional federal borrowing to cover the deficit. The deficit normally increases during recessions and is historically smaller during times of economic expansion. However recently, deficits continue to remain high despite GDP growth. The net result of all those deficits is total federal debt exceeding $40 trillion. The deficit remains high, around $2 trillion annually since 2021.
For many years, the federal government could borrow with relatively little impact on its operating budget. Treasury debt matures on many schedules. Some is issued at very short-term rates, while longer-term debt is refinanced when it matures. When rates fall, the government can refinance at a lower cost. When rates rise, the cost of carrying the debt gradually rises as well.
Federal debt increased 66% from before COVID through the most recent data in this chart, while the cost of servicing that debt increased 127%. As older debt matures and new debt is issued at higher rates, interest expense rises faster than the debt itself.
“A larger borrower becomes increasingly sensitive to the cost of borrowing.”
This is not an attempt to resolve the federal budget. That deserves a separate examination. The point here is narrower: the larger the borrower, the more consequential the cost of borrowing becomes. That is why inflation and interest rates matter so much to the federal government, and why officials care deeply about where rates go next.
Federal income and Spending as Percentage of GDP
The federal budget has not been balanced since the late 1990s. Administrations and members of Congress routinely express a desire for stronger economic growth and smaller deficits. The difficulty is that tax policy, spending priorities, wars, recessions, and emergency programs can work against those objectives. Wanting to close the gap is easier than accepting the tradeoffs required to do it.
“Reducing the deficit doesn’t reduce the debt. The debt continues to get larger, just not as quickly.”
Inflation and Interest Rate Expectations
Interest rates are closely connected to inflation expectations. The more inflation investors expect, the more they generally need to be paid to lend money. A large supply of debt can also place upward pressure on rates because borrowers must compete for investors. The creditworthiness of the issuer, the term of the loan, economic growth, and demand for safe investments all matter. These forces collectively influence interest rates and eventually affect households, businesses, and governments.
“While the federal reserve has tremendous influence over interest rates, the market also can determine the direction.”
CPI- Consumer Price Index
While the federal reserve has tremendous influence over interest rates, the market also can determine the direction.
The chart above shows consumer price index (CPI) since 1960. It’s important to look historically for context of how today’s inflation compares. The previous high inflation period of the 1970s led to double-digit interest rates on consumer borrowing, including for mortgages. We don’t want to get back to that, and the Fed will fight aggressively to avoid it.
“Inflation resets prices. When inflation slows, it doesn’t lower prices back to where they were. It just means that prices don’t go up as quickly.”
CPI- Consumer Price Index
This chart looks more closely at the Consumer Price Index, or CPI, over the past two decades. The Federal Reserve officially defines its 2% inflation target using the Personal Consumption Expenditures Price Index, or PCE, rather than CPI. I use CPI here because it is the measure most people encounter in news reports and discussions about household prices. The two measures are calculated differently and do not always produce the same number, but they generally help us observe the same broad inflation trends.
When inflation remains above the Fed's target and is not convincingly moving lower, the Fed generally has less room to cut rates and may keep them higher for longer. That is not automatic. Employment, economic growth, inflation expectations, and financial stability also influence its decisions. But persistent inflation is a reasonable starting point for understanding why rate cuts may be delayed.
The Fed influences interest rates primarily by setting the federal funds rate and managing its balance sheet. The Federal Open Market Committee, or FOMC, meets eight times a year to consider those decisions.
Interest Rates Over Time
President Trump repeatedly urged former Fed Chair Jerome Powell to lower rates. Lower rates make it less expensive for households, businesses, organizations, and governments to borrow, which can encourage economic activity. But stronger demand can also make inflation harder to contain. Powell raised rates to fight inflation, later reduced them modestly, and then held them steady through the end of his term. Kevin Warsh, who became Fed Chair in May 2026, has continued to keep rates elevated.
Fed Funds Rate
The Fed reduced the federal funds rate to nearly zero after the Financial Crisis of 2008 and again immediately after COVID. When inflation remains above target, the Fed may raise rates or keep them elevated to restrain demand. Higher rates increase borrowing costs throughout the economy and gradually raise the cost of refinancing federal debt.
Economic growth helps the federal budget, but growth alone does not guarantee that the government will outgrow its interest burden. If federal debt and its average interest rate increase faster than federal revenue, interest expense can consume a larger share of the budget even while GDP continues to grow.
“A growing economy can produce more federal revenue while the government’s interest burden still gets worse.”
CPI and Energy
“Of all the elements of inflation, one of the most volatile is the price of energy.”
As the chart shows, energy prices can dramatically influence CPI. Energy affects households, businesses, and government operations through transportation, heating, electricity, and production costs. Since the start of the war with Iran, oil prices have risen sharply. If those increases keep inflation elevated or raise future inflation expectations, the Federal Reserve has less room to lower rates.
That creates consequences elsewhere. Higher rates make it more expensive for the Treasury to refinance federal debt. They can slow housing and business investment. The war did not begin as an interest-rate policy, but its economic consequences can influence inflation, Fed decisions, Treasury borrowing costs, and household finances.
10-Year Bond
The 10-year Treasury yield is often used to illustrate the market's longer-term cost of borrowing. The Federal Reserve influences it, but does not set it. Investors determine the yield through the market as they assess inflation, economic growth, federal borrowing, and risk. When the 10-year yield rises, mortgage rates generally rise with it. Rates on car loans, student loans, and home-equity borrowing can also move higher, although each market responds differently.
The 10-year Treasury yield today is comparable to where it was in the early 2000s. But the federal government's debt burden is now much larger. In 2003, federal debt was approximately $6.5 trillion. Today it exceeds $40 trillion and has recently been increasing by roughly $2 trillion a year. That helps explain why annual federal interest expense has risen above $1 trillion and why Treasury Secretary Scott Bessent speaks so frequently about borrowing costs. The Treasury cannot set market interest rates, but it has a strong interest in them being lower.
Fiscal Policy Debt Management and Monetary Policy
Three major economic functions shape this discussion. They generally share an interest in a productive, growing economy, but they have different responsibilities and can create competing pressures for one another.
Fiscal policy. The White House and Congress make decisions about taxes and spending. Those decisions can support economic growth, but they can also increase deficits or add demand to an economy already experiencing inflation.
Debt management. The U.S. Treasury finances the obligations created through tax and spending laws. It decides how to issue and refinance federal debt, but investors ultimately determine the yields they will accept.
Monetary policy. The Federal Reserve sets short-term interest-rate policy as it pursues stable prices and maximum employment. It may keep rates elevated to contain inflation even when lower rates would make federal borrowing easier and encourage more economic activity.
These objectives frequently overlap, but the actions do not always align. Fiscal policies intended to stimulate growth can add to inflation or federal borrowing. Heavy Treasury issuance can place pressure on market rates. Higher Fed rates can restrain inflation, but they also raise borrowing costs for the Treasury, businesses, and households.
Fed Funds Rate, Inflation, and 10-Year Bond
This is why a development far outside the financial system can affect all three. An energy shock can raise inflation and make the Fed less willing to cut rates. Higher rates can increase Treasury financing costs and slow economic activity. Slower growth and higher interest expense can then make it harder for the White House and Congress to reduce the deficit. None of these relationships is automatic, but understanding the connections provides a useful framework for interpreting the news.
“The institutions can share an objective while their actions create competing pressures.”
Household Financial Resilience
My grandmother lived through the Great Depression. I remember visiting her as a child and seeing how that influenced her, even 50 years later. Her jar of ketchup in the fridge was upside down, and wasn’t thrown out until the very last speck of crusted ketchup could be scraped from the top of the glass bottle and white metal cap. That generation learned the cruel lesson of hardship and strove to have as little overhead as possible.
Later generations experienced very different financial environments. The Dot-Com era brought rapidly rising technology stocks, stock-option wealth, and declining personal savings rates. After that market fell, households encountered unusually low interest rates and lenders willing to extend credit. 'No credit, no problem' appeared on billboards everywhere. The Financial Crisis that followed left its own lasting lessons for the households that experienced bankruptcy, foreclosure, or the loss of home equity.
“Financial environments influence how generations save, spend, and borrow.”
Since the Financial Crisis of 2008, household debt has fallen substantially relative to GDP, while household net worth has grown. It shows that households, in aggregate, are less dependent on debt relative to the economy than they were at the height of the housing expansion.
Today's investors are experiencing another financial environment: one built around immediate transactions. When I was in college, you could bet on which team would win a football game. Today, a person can place hundreds of different wagers on a single game. Investing has changed as well. People can buy fractions of shares, trade options, sell stocks short, use leverage, and turn trading decisions over to systems that operate around the clock.
Technology and artificial intelligence can improve research, organization, and efficiency. But easier access and faster decisions do not eliminate risk. Financial independence is too important to hand over to a system without understanding the decision or maintaining human oversight. History suggests that some expensive lessons will be learned in this environment too.
What This Means for Your Household
Federal debt, wars, oil prices, inflation, and interest rates are enormous forces. Individual households do not control them. But understanding them can still improve the decisions we make. The administration and Congress will continue trying to produce economic growth while managing taxes, spending, and deficits. The Treasury will continue financing federal obligations in changing markets. The Federal Reserve will continue balancing inflation, employment, and economic growth. Geopolitical events will continue complicating all three.
The White House and Legislative Branch can’t control what the Federal Reserve does. The Federal Reserve can’t control what the Executive and Legislative Branches do. None of them, the Treasury, White House, Legislative Branch, or the Federal Reserve can control what the market does. And you can’t control what any of them do.
But you can find control elsewhere.
Protect Your House
Build Liquidity
Maintain enough accessible savings to withstand an income interruption, an unexpected expense, or a period of higher prices. Liquidity gives you time to make a thoughtful decision instead of being forced into one.
Understand Your Debt
Know which debts have fixed rates, which can adjust, how much of your income is committed to debt service, and whether your financial plan depends upon rates falling. Make borrowing decisions based on the possibility that rates remain near today's levels or move higher.
Prepare Before Refinancing Opportunities Arrive
Follow the 10-year Treasury yield and know approximately what mortgage rate would make refinancing worthwhile. Establish the trigger before emotion or advertising influences the decision.
Continue Participating in Economic Growth
Maintain a disciplined savings and investment plan. One of the strongest indicators of future financial success is the percentage of income consistently directed into investments. Do not allow uncertainty about federal debt or interest rates to keep you permanently out of productive assets.
Avoid Turning Investing into Constant Transactions
Access to options, leverage, prediction markets, and automated trading does not make those activities appropriate for building financial independence. The ability to make a transaction instantly is not the same as having a sound reason to make it.
Retain Control of Financial Technology
Use AI and financial technology to improve research, organization, and efficiency. Do not surrender authority over important financial decisions you do not understand. Protect your identity, passwords, financial accounts, and access to everything you have accumulated.
Plan for Taxes
You save money to someday spend it, so pay attention to how it will be taxed when that time comes. Pre-tax retirement withdrawals are generally taxed as income, while qualified Roth withdrawals are tax-free. Roth accounts, HSAs, college savings plans, and carefully evaluated Roth conversions can reduce exposure to future taxes.
You do not need to predict the next war, inflation report, or Federal Reserve decision. You need a financial house capable of handling more than one possible outcome.
“Whatever it is, the way you tell your story online can make all the difference.”
Understand the forces you cannot control. Strengthen the decisions you can control. Protect your house.
