The US Treasury, Federal Reserve System and Federal Deposit Insurance Corporation (FDIC) each perform a specific function within the US monetary system. Following is a brief breakdown of these functions.
Treasury
The US Treasury is an executive department of the federal government responsible for managing federal finances, including collecting revenue, making authorized government payments, managing the public debt, and issuing Treasury securities. Congress determines taxation and appropriates federal spending.
When Treasury issues government payments, those payments enter the monetary system — typically as commercial bank deposits in a recipient’s bank account, accompanied by a matching commercial bank reserve balance held at the Fed.
While the US Congress is responsible for broad spending decisions, Treasury has substantial operational authority to manage financing and the public debt. Federal law authorizes the Treasury Secretary to issue bills, notes and bonds, determine their terms and interest rates, redeem securities, and refinance maturing debt.
Treasury’s authority remains constrained by the debt limit, when one is legally operative. The debt ceiling limits the amount of covered federal obligations — like Treasury bonds and bills — that may be outstanding. Consequently, Congress can create spending and payment obligations for expenditures such as social security benefits, federal employee wages, Medicare reimbursements and more, while separately limiting Treasury's ability to borrow the money necessary to meet them.
This is one reason why debt-limit and funding disputes can become consequential to the US credit rating and investor trust. Prolonged Congressional debate has brought the US Government to the brink of default and resulted in the shutdown of certain federal services at least 10 times, including for a record 76 days in February 2026.
Treasury-led debt buybacks
One of Treasury’s debt management exercises includes buying back debt it has already issued into the market. This is where the roles of the Treasury and Federal Reserve blur. Treasury is managing US Government debt, while the Federal Reserve is managing interest rates. Arguably, interest rate management is also a part of debt management. In this care, there is one notable difference. When the Federal Reserve buys government debt, it creates new currency to do so. Treasury is limited to the contents of its general fund and potentially, its store of physical gold.
Treasury conducted debt buybacks in the 1920s, and then in March 2000 through April 2002. Buybacks resumed again in 2024 and continue at present, in 2026. While debt buybacks are a legitimate debt-management tool, continuous large-scale Treasury intervention in secondary market is not the historical norm.
Treasury typically manages federal debt primarily through regular auctions of new securities, refinancing maturing securities into new debt, adjusting auction sizes and the mix of short and long-term debt, re-opening existing securities to new sales, issuing short-term cash management bills, and maintaining an appropriate cash balance in the Treasury General Account.
The Federal Reserve
The Federal Reserve creates money, including physical currency, and manages its supply and commercial bank liquidity. Commercial banks hold deposits with the Federal Reserve, similar to the way in which a customer at a commercial bank holds a deposit with the commercial bank.
The Federal Reserve is a quasi-independent government agency, with private characteristics — such as shareholders — and public characteristics, such as a governing body that is accountable to Congress. The US Government is ultimately responsible for the debt liability that is the USD, should federal reserve assets (and a portion of shareholder assets) fail to pay off USD liabilities, in the event of a liquidation.
Commercial Bank Reserves and the Creation of the Federal Reserve
Prior to the creation of the Federal Reserve, sudden demand for bank deposits and gold was challenging for a single bank to manage. While banks would rely upon one another to fulfill liquidity needs, there was no central body capable of facilitating what is sometimes referred to as an “elastic” or flexible, monetary supply shared among a national group of banks.
The Federal Reserve System was created in December 1913, when then US President Woodrow Wilson signed the Federal Reserve Act. The following year, the country was divided into 12 Federal Reserve Districts, each with its own Federal Reserve Bank. Member commercial banks were required to maintain reserve balances with their district Reserve Bank. Those balances would not only capitalize the regional banks, but also serve as a foundational cushion for national liquidity management. Because the US Dollar was still exchangeable for gold, the new system transferred cash, gold, and balances with correspondent banks, into the new Federal Reserve accounts.
Because the reserves are on deposit with the Federal Reerve, the accounts are considered an asset of commercial banks, and a liability of the Federal Reserve. Reserves are used primarily to settle payments between banks, meet cash withdrawals and other payment obligations, and provide liquidity. When a customer sends money from Bank A to Bank B, reserves ordinarily transfer from Bank A's Fed account to Bank B's. New reserves are created when the Federal Reserve expands its balance sheet — for example, when it purchases an asset and credits a bank's reserve account, or when it lends to a bank. Reserves can also be extinguished when those transactions reverse.
Governance
The Federal Reserve’s Board of Governors — which drives US interest rate policy — is an agency of the federal government. The board consists of seven governors nominated by the US President and confirmed by the Senate. Governors serve 14-year terms, with one term expiring every two years. Leadership terms last four years.
Beneath the Board are the 12 regional Federal Reserve Banks. Commercial banks that are members of the Federal Reserve System are required to subscribe to stock in their regional Reserve Bank. This stock serves in part as a liquidity backstop. Unlike corporate stock, reserve bank stock cannot freely be bought, sold or pledged; it does not confer proportional ownership or control over the Federal Reserve. Member banks receive a statutorily determined dividend on their paid-in capital, based on bank size. In 2025, the 12 Fed banks paid out USD 1.69bn to member banks, though in recent years, the total payout has landed below USD 1bn.
Each Reserve Bank has nine directors divided into three classes. The classes are intended to provide a broad cross-section of input for the purpose of governing the banks and setting discount rates. Three Class A directors are elected by member banks to represent member banks; three Class B directors are elected by member banks to represent the public; and three Class C directors are appointed by the Board of Governors to represent the public. Reserve Bank presidents are appointed by their eligible directors, subject to approval by the Board of Governors, and serve five-year terms.
Federal Reserve Funding
The Federal Reserve does not rely on Congressional appropriations. It finances itself primarily through income on securities the reserve banks hold — such as Treasurys and Agency MBS — along with income gained through loans extended to its member commercial banks, and service fees. In 2024, the Federal Reserve banks recorded a total of USD 524m in fee revenue.
Federal Reserve bank earnings are paid out in a statutorily designed sequence, beginning with operating expenses. Next, the member bank dividends are paid, and then the applicable surplus is funded. If there is anything remaining, Treasury gleans the residual. If the Fed does not have enough money to pay for its expenses, surplus, and dividends, it has an earnings shortfall, referred to as a deferred asset.
Beginning in the fall of 2022, most Federal Reserve Banks suspended weekly remittances to Treasury as their earnings became insufficient to cover expenses, member bank dividends and required surplus. Deferred assets are the future net earnings each bank must generate before resuming Treasury remittances. Individual Reserve Banks can eliminate their deferred assets and resume remittances even while the Federal Reserve System as a whole continues to report a substantial consolidated deferred-asset balance.
Before the Federal Reserve began experiencing operating losses in 2022, its Reserve Banks commonly remitted tens of billions of dollars of excess earnings to Treasury each year. From 2010 through 2021, remittances were generally between USD 50bn and USD 117bn annually, with USD 109bn remitted in 2021. The Federal Reserve held a USD 226bn deferred asset as of mid-2026.
Federal Reserve Stock
Commercial banks who are members of the Federal Reserve system are generally required to subscribe to Federal Reserve Bank stock equal to 6% of its capital and surplus. Three percent of that subscription is actually paid in, while the remainder is considered “on call.” When the Federal Reserve Banks pay dividends to the commercial banks, the dividends are typically calculated as 6% of that paid-in bank stock. Largest banks receive the lesser of 6% or the yield on the most recent 10-year Treasury auction.
The practice dates back to the creation of the Federal Reserve. The Federal Reserve Act required member commercial banks to subscribe to stock in their district bank in order to provide initial funding and a liquidity backstop. Its dividend payout is a fixed percent of the portion of capital and surplus paid in by the member bank. Residual profits of the reserve banks are paid to Treasury, not the member banks. In 2025, payouts were USD 1.69bn across all of the member banks; in 2020, member banks earned USD 386m, and in 2007, the year before the financial crisis, member banks earned USD 992m.
Federal Reserve Bank Surplus
Historically, Federal Reserve Banks were able to hold a surplus account equal to the amount of capital it held as a result of the commercial bank stock buy-ins. While the idea of a “deferred asset,” in place of actual operating losses was traditionally available, reserve banks traditionally drew down this surplus during periods of loss. In this sense, the surplus acted like a liquidity cushion for the reserve banks.
Congress ended this practice. It began by capping aggregate reserve bank surplus to USD 10bn in 2015, to USD 7.5bn in 2018, USD 6.825bn in 2018 and USD 6.785bn in 2021. Now, reserve banks collectively hold USD 6.785bn in reserves, allocated proportionally to balance of paid-in commercial bank stocks. If the system stood in its original form, the reserve banks would hold USD 40.9bn in surplus, equivalent to the USD 40.9bn of paid-in commercial bank stocks as of August 2026.
Interest Rates & Autonomy: Fact or Fiction
Is the Federal Reserve really independent of the US Government? Not really. But its monetary policy is supposed to maintain an equilibrium between US Government spending and the economy’s capacity to absorb that spending. The Federal Reserve’s objectives do not always align with spending priorities of the US Government.
Prior to the 1951 Treasury-Federal Reserve Accord, which laid the foundation for the modern separation between Treasury’s federal debt management role and the Federal Resreve’s monetary policy role, the Federal Reserve subordinated monetary policy to federal debt financing of the US role in WWII.
Federal debt rose from roughly USD 49bn in 1941 to roughly USD 269bn in 1946; that amounted to a debt-to-GDP ratio of roughly 40% before the war, to roughly 119% after the war. From 1942 until 1951, the Fed supported a low-yield Treasury curve, including a 0.375% rate on Treasury bills and a 2.5% ceiling on long-term government bonds.
While inflation was initially suppressed by wartime price controls and rationing, inflation surged when the measures were removed in 1946. Consumer prices rose by 17.6% between June 1946 and June 1947, and another 9.5% between June 1947 and June 1948. Inflation surged again due to Korean War spending; be February 1951, consumer price index inflation was running at an annualized rate of 21%.
Similarly, US President Donald Trump has repeatedly advocated for low interest rates and publicly pressured Federal Reserve leadership over monetary policy. Moreoever, as long-term Treasury rates rose to a twenty-year high of 5.33% in August 2026, the US Treasury announced it would increase purchases of long-dated government debt outside of its quarterly refunding process. It said it would at least double the maximum size of its liquidity-support buybacks in 10 year - 20 year and 20 year - 30 year bonds, raising purchased from USD 2bn to at least USD 4bn per operation. This led to speculation that the US Treasury was taking an “activist” stance in order to lower long-term interest rates on its own accord.
How much capacity does the US Treasury hold to manage interest rate policy? Treasury held just under USD 1trn in its general account as of August 2026. Separately, it holds gold which, at today’s market price, is valued at about USD 1.2trn. Treasury can spend gold to buy government debt with presidential approval. Still, Treasury’s capacity to buy long-dated debt is no comparison with the Fed, which can do so while creating its own money.
Approximately 33% of outstanding government debt is maturing in the next 12 months — or roughly USD 10.5trn — and this amount is heavily concentrated in short-term Treasury Bills. Between 2026 and 2028, USD 15trn of US debt is maturing. While the Fed generally holds up to 70% of any individual Treasury security, it is prohibited from buying securities directly from Treasury. The Fed held roughly USD 4trn in US Government debt as of August 2026.
Fed Reserves
When the Fed buys Treasuries from US commercial bank holders, it pays those banks with reserve balances. Since 2008, those reserve balances have paid interest to the banks who hold them; the interest rate was 3.65% as of August 2026. The interest the Federal Reserve pays on these balances, compared to the interest rate on US Government debt, is one of the reasons for its earnings shortfall. Paying interest to commercial banks on reserve balances is an incentive for the banks to hold the reserves. Commercial bank reserves draw down when the banks lend money. As a result, the interest payments are a means to infuse commercial banks with money, while keeping lending activity subdued. The reserve interest rate also helps to enforce short-term interest rates, such as the inter-bank lending rate.
The Reserve Banks maintain the accounts through which commercial banks hold central-bank reserve balances. These balances are assets of the commercial banks but liabilities of the Federal Reserve Banks. They provide the central settlement layer for payments between banks. Reserve balances held at Federal Reserve Banks were approximately USD 3.07trn on May 27, 2026. In 2024, Fed member banks were only about 35% of commercial banks by number but operated about 70% of all U.S. commercial-banking offices.
Federal Reserve notes and collateral
The Federal Reserve was once responsible to maintain a 40% ratio of physical gold to USD notes outstanding. Moreover, Reserve Banks once had a requirement to maintain a 35% ratio of physical gold to its commercial bank reserves. The responsibility to maintain gold reserves was an entirely different dynamic for the Federal Reserve to manage, compared to the current fiat currency system.
When the USD was no longer convertible into gold, the liability for the notes shifted — from the US Government’s ability to maintain gold reserves to the US economy’s ability to generate ongoing debt payments. Nearly three-quarters of gold held at the US Treasury today — 195m fine troy ounces out of 261m fine troy ounces — was once transferred from the Federal Reserve and private citizens from 1933 - 1934.
Unlike ordinary commercial-bank deposits, notes circulating outside the Reserve Banks are subject to a statutory collateral requirement. Eligible collateral includes gold certificates, US Government and agency obligations, SDR certificates, loans and foreign currency assets. In addition, Federal Reserve notes have a “first and paramount lien” on all assets of the issuing Reserve Bank.
The Federal Reserve Board of Governors has the statutory authority to suspend the operations of an individual reserve bank for violation of the Federal Reserve Act. It may take posession of the bank, reorganize it, or liquidate it. In the case of liquidation, Federal Reserve notes are first collateralized by the issuing bank’s assets; if this is insufficient to cover the notes’ dollar value, the US Government is then liable.
This arrangement is inherently circular. Treasury securities — interest bearing debt promising future dollar payments — are among the primary assets that collateralize Federal Reserve notes, which are themselves monetary obligations of the United States. In essence, one form of government debt is backing another form of government debt. In the case that all Federal Reserve banks were liquidated at once, it is unclear how the value of the notes would be renumerated.
The FDIC
The Federal Deposit Insurance Corporation performs another function entirely. It does not create bank reserves or issue Federal Reserve notes. It insures qualifying deposits at insured banks and acts as receiver when insured banks fail. Standard coverage is generally USD 250,000 per depositor, per insured bank, per ownership category.
The FDIC is not funded by ordinary taxpayer appropriations. Its Deposit Insurance Fund (DIF) is funded principally by risk-based assessments charged to insured banks, plus investment income earned on the fund's holdings of US government obligations. The assessment base is broadly based on an institution's assets minus tangible equity, rather than simply the amount of insured deposits. The DIF itself is backed by the credit of the United States.
As of the first quarter of 2026, the FDIC reported 4,287 insured commercial banks and savings institutions. The DIF stood at approximately USD 157.4bn, against an estimated USD 11trn of insured deposits, giving it a reserve ratio of approximately 1.43%. That does not mean only USD 157bn could ever be paid: bank resolutions involve recovering and selling assets of failed institutions. But it illustrates that deposit insurance is an insurance/resolution structure, not a dollar-for-dollar collateral pool sitting beside insured deposits.
The FDIC can borrow up to USD 100bn from Treasury at one time, via public debt issuance. It may also borrow from the Federal Financing Bank, or from insured banks, or Federal Home Loan Banks.
If an insured bank is allowed to fail, it is generally transferred to FDIC receivership, where its assets and liabilities are either transferred or liquidated. If a particular bank is considered a systemic risk exception, its depositors with accounts holding more than USD 250,000 may be made whole via a special assessment charged to all FDIC-insured banks. Such was the case with Silicon Valley Bank, where 88% of deposits would have been uninsured when it collapsed in March 2023. Instead, FDIC member bank assessments made up for the estimated USD 16.7bn shortfall.
During a systemic crisis, such as the 2008 Financial Crisis, government authorities may conclude that that the failure of an otherwise viable institution or the collapse of an entire funding market, threatens the broader financial system. This was the rationale for extraordinary bank liquidity programs such as Treasury’s Troubled Asset Recovery Program, or the Federal Reserve’s Troubled Asset Loan Fund, to name a few. Emergency facilities must be broadly based and cannot be designed to rescue a particular involvent company, according to post-Dodd-Frank rules.
