Blankfein states private credit lacks transparency, is illiquid, and its assets are difficult to value accurately because they don't transact frequently. He draws a direct analogy to the problematic "triple A" securities before the Global Financial Crisis. Illiquidity and reliance on models (rather than market sales) for valuation can lead to assets being incorrectly marked on balance sheets. When a forcing event occurs, the discrepancy between marked value and realizable value can cause rapid, cascading write-downs. The structural similarities to pre-crisis instruments and the inherent opacity make the asset class risky. The prudent stance is to avoid exposure due to the potential for sudden, severe repricing. A market shock that forces widespread selling would reveal the true, lower market price for these instruments, triggering losses.
Blankfein asserts that banks are "not that leveraged" to risky non-financial firms and are in "much better shape" today with stronger balance sheets than before the Global Financial Crisis. Higher capital levels mean asset values can decline significantly before bank solvency is threatened. This robustness means a future recession would likely not originate from or be severely compounded by a banking crisis, giving policymakers functional tools to respond. The banking sector is not a source of systemic risk at this moment. This does not imply a bullish view on bank stocks, but rather that the sector's stability is a neutral/positive background condition for the broader economy. A crisis severe enough to overwhelm the improved capital buffers, or a crisis that originates outside the banking system but contaminates it through unexpected channels.
