The simple take on bond curves and all kinds of changes is they are bonds that promise to pay dollars in the future. With an unwinding of debt we will see more dollars in circulation and so currency weakness. The trend for the majority of my life over decades has been oppisite, more debt, more tightly wound at higher prices. That trend will end after a time that has lasted a generation basically, volatility and change ensues.
When the economy is in a downturn, bitcoin will be a top choice because it is a decentralized market that will not be affected by external factors.
Bitcoin is traded globally and will be effected by a change in the world economy and its currencies. What has to be true by that point is that Bitcoin is a usable and useful tool to have no matter the status high or low of that world citizen. I would not assume Bitcoin is a perfect ship that will rise above all troubles, they'll be many waves and it'll have challenges pretty sure.

BTC is not bound to that debt problem but it has a struggle to be efficient in its operation like every system in use
