US Fed Balance Sheet (Sep/09) 6.741T (Prev. 6.737T)

In past tightening and runoff cycles, the balance sheet has mattered at the margin through reserve scarcity, visible in repo stress and the spread of secured rates to the policy corridor, not through the headline level itself. The distinctions worth drawing are between the securities portfolio, which follows the runoff caps, and the liability side, where a rising TGA or falling reverse repo take-up drains reserves even when the total is stable. An uptick of this kind, after a long grind lower, typically reflects bill issuance or facility usage rather than a shift in stance. What carries information in these releases is a break in trend: a sustained rise in discount window borrowing or a sudden portfolio expansion has historically been the tell of funding stress or an operational pivot. Absent that, the print is housekeeping.
