Where did the money to bid those speculative asset prices up come from?
It’s not “let’s bet some free money on the price of gas increasing”. It’s “we need to secure enough gas to keep the factory running next year, let’s buy as much as we can at any price we can reasonably turn a profit at”.
People continued to bid the price of residential real estate up solely because they believed there was a lack of housing starts?
Or maybe — just maybe — the ZIRP free money spigot had something to do with it as well.
I agree with you that the financial economy is largely divorced from actual stuff, which is why pumping money into it doesn’t lead to rising prices of stuff, just rising prices of financial instruments.
That’s the key here. Increasing the money supply should lead to increase in prices if and only if it is spent on stuff. If it’s squirreled away in complex financial instruments, we just call it “amazing returns”
To use housing as an example, as housing prices rise on paper, banks can approve ever larger mortgages to purchasers of those houses, which can drive the prices still higher, and so on. This borrowing temporarily creates new money in the system, independently of any action from the government or central bank. This loop can only persist temporarily, but temporarily can last a long time.
Central bank free money certainly can tie into it and IMO almost definitely did. Speculative asset bubbles seem to happen more easily in low interest rate environments, and bubbles can be halted early by responsible government / monetary policy. (Or conversely, allowed or encouraged to continue for far too long by irresponsible policy). Speculation on something money-adjacent, like gold or bitcoin, can happen in anticipation of future government money printing that may or may not happen. Anticipation of official or unofficial government backstops of financial institutions or pension funds can also create moral hazards that incentivize private lending into a speculative asset bubble without due risk management.
But bubbles can also apparently happen all on their own.
(And of course an increase in asset prices can also be caused by a genuine increase in the fundamental value or productivity of those assets, which hopefully has occurred to some extent over 15 years of hard work, so it's not all speculation.)
There has been bidding of speculative asset prices even when the money supply was fixed under the Gold Standard, cf 1920s Wall Street.
