What is CP–T-bill Spread?

CP–T-bill Spread (90D AA Financial CP minus 3M T-bill) 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 "higher_worse" direction, meaning rising values signal tightening liquidity conditions. This directional assignment is based on the historical relationship between the indicator's movement and subsequent risk asset performance.

DCPF3M − DTB3 — 90-day AA financial commercial paper rate minus 3-month Treasury Bill rate. The TED-style post-LIBOR funding-stress proxy: financial issuers include large US branches of foreign banks, so the spread carries a real offshore component. Widens at SVB-style stress events.

Why CP–T-bill Spread matters for risk assets

Changes in CP–T-bill Spread 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 CP–T-bill Spread 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.

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: Read it beside the DLI score, not inside it — CP–T-bill Spread is reference context and never appears as a score driver, so its job is to explain or contradict what the headline is doing, not to move it.

Pay attention to divergence instead: when CP–T-bill Spread moves hard while the DLI score stays flat, that gap is the signal. A context indicator earns its place precisely when it disagrees with the headline.

Common mistakes and better workflow

Mistake: assuming everything charted on this site feeds the score. CP–T-bill Spread does not — it carries zero weight in the DLI and can never show up as a listed driver. Reading a move here as "so the score should have changed" is the single most common error with reference indicators.

Better workflow: Start with the score reading on the homepage. Then check the top drivers. Only then drill into CP–T-bill Spread if it's flagged as significant. This top-down approach prevents single-indicator tunnel vision. Combine with Fed Swap Lines, SOFR-IORB, HY Spread for the most complete assessment.
