US Banks Have $620 Billion of Unrealized Losses on Their Books  https://www.bloomberg.com/graphics/2023-svb-exposed-risks-banks/?ai=eyJpc1N1YnNjcmliZWQiOmZhbHNlLCJhcnRpY2xlUmVhZCI6ZmFsc2UsImFydGljbGVDb3VudCI6MCwid2FsbEhlaWdodCI6MX0= 

The investment losses that helped take down Silicon Valley Bank are a problem, to one degree or another, across the US financial system. In total, the industry ended last year with $620 billion of unrealized losses on its books from investments in low-yielding bonds.

For most banks, the issue is manageable.

Bonds held in investment books represented less than a quarter of the banking system’s $23.6 trillion of assets in December, and unlike SVB, lenders usually have a wide array of depositors who are unlikely to all need money around the same time. For the biggest banks, the risks are even smaller. They are perceived as too big to fail. What’s more, the recent rally in the Treasury bond market — sparked, ironically, by the jitters about the health of the banking industry — is helping to shrink the $620 billion of paper losses. (In the coming weeks, banks will start to post first-quarter data.)
