That's a good question. Thank you for it.
In simple terms, a bank will issue different varieties of short-term and long-term debt securities to fund itself in the ordinary course where those creditors are funding the bank for a return over time and there are different types of instruments. Those instruments are issued and they're also traded on the secondary market, much like on the other side of the balance sheet you have shareholder equity where you'll have common shares that are issued and held by individuals, but are also traded in the secondary market.
On any given day, shares or debt securities are constantly being traded, based on the market scenario and their understanding of the profitability of an institution.
I can't speculate on whether new instruments will be created, but I can say on any given day in the normal course or in stress times the market on both sides does work as it should, and it offers pricing scenarios on both of those instruments. I would see that as a normal functioning of the marketplace.
