PG&E Borrow Cost Explodes 518% as Options Traders Load Up on Calls

Three distinct signals have converged on PCG in a single session. The borrow market tightened sharply overnight, short interest jumped 25% in one day, and options traders are piling into calls at near-record pace.

The Borrow Story

Cost to borrow hit 2.27% on June 25. That is a 518% jump in one week. For context, PCG's CTB had been running between 0.19% and 0.59% for the entire prior month. The move happened in a single session — from 0.19% on June 24 to 2.27% on June 25.

Availability remains extremely loose in absolute terms at 4,762%. That means the sharp CTB spike reflects a sudden, concentrated demand for borrows — not a structural shortage in the lending pool. Someone moved fast to establish a short position, and the market charged them for it.

Short interest estimates rose from roughly 36.6 million shares to 45.8 million shares on the same day. That puts SI at 2.1% of free float. It is still low in absolute terms for a large utility, but the one-day magnitude of the move is the story here.

Calls Dominate Options Flow

Options traders are pointing in the opposite direction. The put-call ratio on PCG sat at 0.14 on June 25. The 20-day mean is 0.167. The ratio has been below 0.13 as recently as June 22 — the lowest reading in at least a year.

That is an aggressive tilt toward calls. It sits near the 52-week low for PCR, meaning the options market has rarely been this bullish on PCG over the past year. The divergence between the lending desk and the options desk is the key tension right now.

Context: Analysts and Upcoming Earnings

Analyst sentiment leans constructive. JP Morgan holds Overweight with a $23 target. Barclays carries Overweight at $23. Truist maintains Buy. The mean price target sits at $22.59 — roughly 32% above the current $17.08 close. Even Jefferies, which downgraded to Hold in March, kept a $19 target.

Earnings land on July 23. Recent earnings moves have been muted — PCG moved just +1.1% and -1.6% on the last two prints. But the convergence of a sudden borrow demand spike and aggressive call buying arriving four weeks before results is worth tracking.
