I am not suggesting that monetary policy is
everything. Secular trends, like the tendency for software and hardware to get cheaper, can't be ignored. But to ignore the direct and
indirect impacts of monetary policy altogether doesn't make sense either.
Silicon Valley-specific example: Facebook goes public during what many believe is a Fed-supported bull market. Insiders sell stock at close to a $100 billion valuation; it's estimated that more than 1,000 employees get to sell stock worth at least $1 million a few months later. Some of the gains realized by insiders and employees will be funneled back into startup investments as those insiders and employees become limited partners in venture funds or angel investors themselves.
Now consider this dynamic across the entire tech industry. Numerous companies have taken advantage of the IPO window of the past several years, and have been able to go public at rich valuations. Many employees with equity compensation at established publicly traded tech companies have done very well too, and ironically some of the most exorbitant valuations are at large companies lacking earnings.
It would be foolish to believe that none of this has impacted the amount of money being thrown at VC firms, super angel funds and startups through direct angel investment, which in turn impacts valuations, deal terms, etc.
The big question: when the great experiment of the central banks ends, how will this affect the landscape for investments in startups? I have some ideas which may or may not be right, but it's simply not credible to believe that there will be no change. The fact that few investors in Silicon Valley seem to be talking about this, however, suggests that they believe they live in a vacuum completely disconnected from the rest of the economy and global financial system. The last time this happened, it didn't end well.
