ChatGPT - OpenAI: Should bank regulators/supervisors be aware of risks with US Treasury long term bonds?

I asked ChatGPT:

"Should bank regulators or supervisors be aware of the duration risk, interest rate risk with US Treasury long term bonds?"

ChatGPT answered:

"Yes, bank regulators or supervisors should be aware of the duration risk and interest rate risk associated with long-term US Treasury bonds held by banks.

Duration risk refers to the risk that a bond's price will decline due to changes in interest rates. When interest rates rise, the price of a bond with a longer duration will fall more than that of a bond with a shorter duration. Banks that hold long-term US Treasury bonds are exposed to duration risk because if interest rates rise, the value of these bonds will fall, leading to a decline in the bank's capital.

Interest rate risk refers to the risk that changes in interest rates will impact the bank's earnings and capital. If interest rates rise, the value of a bank's bond portfolio will decline, leading to a reduction in the bank's capital. Banks that hold long-term US Treasury bonds are exposed to interest rate risk because these bonds are highly sensitive to changes in interest rates.

Therefore, bank regulators or supervisors should be aware of the duration risk and interest rate risk associated with long-term US Treasury bonds held by banks. They should monitor the bank's bond portfolio and ensure that the bank has sufficient capital to withstand potential losses due to changes in interest rates. Additionally, regulators may require banks to conduct stress tests to evaluate the impact of changes in interest rates on their capital and profitability."

PS. My most recent takes on this:

1988 30 pages Basel I stated: “36. Claims on central OECD governments will attract a zero weight (or a low weight if the national supervisory authority elects to incorporate interest rate risk).” So, for 35 years, why did national regulators not consider that risk?
