Higher U.S. Rates Could Lift Iraq’s Reserve Income, Not Its Borrowing Costs

Key Points

1. The Federal Reserve raised its benchmark range 25 basis points to 3.75%-4.00% on September 16, citing elevated inflation.
2. Iraq's domestic borrowing costs track Central Bank of Iraq policy and bank liquidity, not Federal Reserve decisions.
3. The gain would be financial: dollar reserves reinvested at higher yields can generate more income for the state.

The latest:

A 25-basis-point Federal Reserve increase to a 3.75%-4.00% range, announced September 16 and justified by still-elevated inflation, reaches Iraq through an unusual channel. Baghdad is largely insulated from the transmission that links U.S. rates to mortgages and corporate credit in advanced economies. But it holds large reserves abroad, and maturing dollar securities can be reinvested at higher yields.

Details:

• Limited transmission: Iraq’s domestic interest-rate environment is set primarily by Central Bank of Iraq policy, banking-sector liquidity and the structure of the financial system, rather than directly by Federal Reserve moves. That insulation is the core reason a U.S. hike does not translate into higher Iraqi lending costs.
• Baghdad’s own cycle: The CBI reported that its monetary-policy rate was cut from 7.5% to 5.5% in 2024, easing while Washington held rates elevated. The divergence illustrates that Iraq can run a rate cycle in the opposite direction from the Federal Reserve.
• The dollar link: Iraq remains heavily tied to the dollar through oil revenues, foreign reserves and its exchange-rate framework, which keeps U.S. financial-market conditions relevant to state finances even without a direct rate channel.
• The reserve upside: Higher U.S. rates generally lift yields on newly issued Treasury bills and other short-duration securities. For a central bank rolling over maturing assets, that can raise investment income without any change in the size of the portfolio.
• Important qualification: A Fed hike does not automatically increase the value or income of every Treasury security already held. Existing fixed-rate bonds can lose market value when yields rise, so the effect depends on what is held and for how long. The benefit is clearest for short-term and maturing assets reinvested quickly.
• Disclosed exposure: The CBI’s audited 2023 financial statements listed exposure to the U.S. Department of the Treasury at IQD 40.844 trillion, alongside holdings and balances with other foreign institutions, confirming that U.S. government securities form a significant part of the reserve portfolio.
• The 2025 figure: More recent CBI data show roughly IQD 45.1 trillion classified as “securities held to maturity” as of October 31, 2025. The published balance sheet does not identify all of those securities specifically as U.S. Treasuries, and it gives no maturity breakdown.
• A claim unsupported: Assertions that the CBI currently holds exactly $40 billion in U.S. Treasury securities do not follow from the latest published CBI disclosures. The broader mechanism still holds: large dollar reserve portfolios earn more as cash and maturing paper are reinvested.
• The comparison: For European economies and Britain, U.S. tightening can move currencies, bond yields and capital flows, but their central banks are not mechanically obliged to follow the Fed. Their decisions rest primarily on domestic inflation, growth and currency conditions.

Between the lines:

The asymmetry cuts both ways. Because Iraqi borrowing costs answer to the CBI rather than the Fed, as the 2024 cut from 7.5% to 5.5% showed, Baghdad escapes the household and corporate rate shock felt in more financialized economies. The offsetting benefit is narrower than headline reserve figures suggest: without a published maturity profile for the IQD 45.1 trillion in held-to-maturity securities, the share that can actually be reinvested at higher yields is not derivable from the disclosed data.
