What Is Bank Reserves?

What is Bank Reserves?

Bank Reserves (Reserve Balances at the Fed) is tracked in our framework because it captures a distinct dimension of US dollar liquidity. The DLI headline is built from the net-liquidity flow — the Fed balance sheet minus TGA minus ON RRP — plus an acute funding-stress override (SOFR-IORB, SRF). Policy and funding inputs drive that headline directly; credit and market-risk inputs are shown as context panels on the liquidity map alongside it.

The indicator uses a "lower_worse" direction, meaning falling values signal tightening liquidity conditions. This directional assignment is based on the historical relationship between the indicator's movement and subsequent risk asset performance.

WRESBAL — reserve balances held by depository institutions at the Federal Reserve, in trillions of USD. The raw cash level of the banking system, and the number market participants watch for "reserve scarcity" (the level fell from a ~$4.3T peak toward ~$3T as QT drained it). Display-only context, NOT in the DLI score: the headline tracks the net-liquidity FLOW (is liquidity being added or drained now), and reserves enter that flow via WALCL − TGA − ON RRP. The absolute level is shown here because it is the figure traders quote, while the reserve-buffer ratio normalizes it against bank assets. A reserve LEVEL was deliberately kept out of the score — it anti-tracks financial conditions in an ample regime.

Why Bank Reserves matters for risk assets

Changes in Bank Reserves influence the broader liquidity environment through both direct and indirect channels. Directly, it affects the cost or availability of funding. Indirectly, it shifts market expectations about future policy or credit conditions.

For Bitcoin and equities, the impact is most visible when Bank Reserves moves to extreme z-scores (above +1.5 or below -1.5). At these levels, the historical correlation with risk asset returns strengthens significantly. Moderate moves within the normal range tend to have weaker predictive power.

Cross-reference with Reserve Buffer, ON RRP, TGA Balance, Fed BS Size, Net Liquidity for multi-indicator confirmation. The strongest signals come when multiple related indicators move in the same direction.

How to interpret daily updates

On the indicator detail page, follow this 3-step process:

Step 1: Check the percentile (5Y) to understand historical context. Above the 75th percentile is noteworthy; above the 90th is extreme. Step 2: Review the 7-day and 30-day trend direction — trend matters more than any single reading. Step 3: Check the homepage score card to see if this indicator is listed as a key driver and in what direction.

Pay attention to score transitions: when Bank Reserves shifts from tightening to easing contribution (or vice versa), it often coincides with broader score shifts that create investable signals.

Common mistakes and better workflow

Mistake: Overweighting a single indicator. Bank Reserves is only one component within its sub-index tier. If other indicators in the same tier disagree, the tier sub-score will dampen Bank Reserves's contribution before it reaches the composite DLI.

Better workflow: Start with the score reading on the homepage. Then check the top drivers. Only then drill into Bank Reserves if it's flagged as significant. This top-down approach prevents single-indicator tunnel vision. Combine with Reserve Buffer, ON RRP, TGA Balance, Fed BS Size, Net Liquidity for the most complete assessment.
