First Republic has been rescued. It hasn't been saved

On 16 March, a consortium of eleven of America’s largest commercial banks, orchestrated by JPMorgan Chase and Treasury Secretary Janet Yellen, deposited $30 billion of uninsured cash into First Republic Bank. The move was hailed as a majestic demonstration of private-sector solidarity, designed to restore confidence and insulate the San Francisco-based lender from the contagion that destroyed SVB. Yet anyone who examines First Republic’s balance sheet understands that this intervention was merely an emergency liquidity bridge over a widening solvency canyon. First Republic has been rescued from an immediate weekend seizure, but it has not been saved from the mathematical reality of its underlying business model.

First Republic’s fatal flaw was not speculative crypto bets or venture capital mania; it was an ultra-conservative, high-touch wealth management strategy that built an immaculate loan portfolio of jumbo mortgages to wealthy individuals at fixed rates between 2.5 and 3.0 per cent.

The Underwater Balance Sheet

While the credit quality of these affluent borrowers is pristine, the duration risk is lethal. With mortgage rates north of 6.5 per cent, First Republic’s loan and securities portfolios are burdened with over $25 billion in unrealised mark-to-market losses—a sum that completely wipes out its tangible common equity.

The $30 billion of rescue deposits from big banks does not repair this capital impairment; it merely replaces low-cost deposits that fled with short-term wholesale deposits that cost market rates near 5 per cent.

The Negative Carry Trap

First Republic is now trapped in a fatal negative carry. The bank is paying 4.5 to 5.0 per cent for its wholesale borrowings and rescue deposits, while its assets yield an aggregate average below 3.5 per cent.

The bank is bleeding operating cash flow with every passing business day, destroying its remaining franchise value. Without a government-subsidized buyer willing to absorb the duration impairment at par, private recapitalization is commercially impossible. The $30 billion lifeline bought time for Washington regulators, but subsidising an institution whose funding costs permanently exceed its asset yields is an unsustainable charade that merely delays an inevitable FDIC resolution.
