Most investors assume that when the Federal Reserve cuts rates, borrowing costs fall and liquidity improves across the system. That relationship may not hold in the next easing cycle.
Having spent years in bank liquidity risk management, where Fed policy directly shapes how institutions value deposits and manage balance sheets, I’ve seen how regulatory and policy changes translate into real-world pricing. Those mechanics are starting to shift in ways that may not be obvious from headline rate moves.
Evolving bank regulation, changes in Fed leadership, and renewed focus on balance sheet policy could produce a different outcome: short-term rates may decline, but financing costs and deposit dynamics may not move in lockstep.
1) Bank Liquidity Rules Are Changing
Banks do not hold liquidity by preference; they hold it based on regulation, supervisory expectations, and internal stress testing. Those assumptions are beginning to change.
Recent supervisory discussions and market practice have placed greater emphasis on the usability of contingent funding sources, including Federal Home Bank Loan access, discount window readiness, and repo capacity, as part of broader liquidity planning. If banks place greater confidence in those sources, some may feel less pressure to maintain large excess reserve balances at the Fed.
What this means in practice:
- Some banks may place less value on excess deposits, especially balances not tied to operating activity
- Deposit pricing may become more uneven across institutions
- Baseline demand for “idle” cash could decline over time
This does not mean deposit rates fall everywhere. Banks still compete for operating accounts and relationship-driven balances. But it does suggest more selective demand, which changes how pricing behaves.
2) The Balance Sheet May Matter More Than the Policy Rate
Markets tend to focus on the federal funds rate because it is the most visible tool. But the Fed’s balance sheet plays a different role.
- The policy rate primarily affects short-term borrowing costs
- The balance sheet influences longer-term yields, term premiums, and mortgage spreads
In the past, these tools often moved together. Looking ahead, they may not.
There is a credible scenario in which the Fed lowers short-term rates while continuing to reduce the size of its balance sheet. That combination would have mixed effects:
- Lower short-term rates would reduce yields on operating cash and floating-rate debt
- Continued balance sheet runoff would leave more Treasuries and mortgage-backed securities for private markets to absorb, which could keep pressure on longer-term yields and spreads
A simple example illustrates the point: a real estate operator refinancing a property may see floating-rate costs decline by 50–100 basis points, while fixed-rate financing tied to longer-term yields declines far less, or not at all.
For investors and operators:
- Floating-rate borrowing costs may fall relatively quickly
- Fixed-rate financing may not move by the same magnitude
- Mortgage spreads and long-term yields could remain elevated relative to past easing cycles
3) Inflation Measurement May Affect Timing, Not Outcomes
There is also growing discussion around placing more weight on measures like the trimmed-mean PCE, which aim to capture underlying inflation by removing extreme price movements.
If policymakers place greater weight on measures of underlying inflation, such as trimmed-mean PCE, and those readings remain closer to target, it could strengthen the case for lower short-term rates even if headline inflation remains uneven.
The practical implication:
- Rate cuts could come sooner or more consistently
- But longer-term borrowing costs may not respond in the same way
The key issue is not simply whether rates fall, but which rates move and by how much.
What This Means for Deposits and Borrowing
Taken together, these dynamics point toward a more differentiated environment:
Deposits
- Rates may decline overall, but vary more across institutions
- Operational balances may be valued differently than excess liquidity
Borrowing Costs
- Floating-rate borrowers may see earlier relief
- Fixed-rate borrowers remain tied to longer-term yields and spreads
Bank Behavior
- Credit decisions may become more selective
- Relationship value may matter more than benchmarks
A More Active Approach
In a more uniform rate environment, these differences are less visible. When liquidity is abundant and spreads are compressed, the cost of inaction is relatively small.
That may not be the case going forward.
If deposit pricing becomes more uneven and borrowing costs move at different speeds, then how cash is managed and how financing is structured can have a measurable impact on outcomes. That can include separating operating cash from excess balances, benchmarking yields across institutions, and reassessing fixed versus floating rate exposure.
Bottom Line
The next phase of Fed policy may look familiar on the surface, rate cuts in response to moderating inflation, but the underlying mechanics could be different.
For investors and operators, the key question is not simply whether rates are going up or down. It is how those changes move through deposits, borrowing costs, and bank behavior. Understanding that transmission may matter more than the direction of rates itself.
