Okay, I’m no electrical engineer and have no expertise in equipment design, but I have spent my career in finance as a market strategist and money manager so take this for what it’s worth. In normal times you’d think raising rates leading to a slower economy, decreased demand, and possibly a recession then yes, eventually audio prices might come down somewhat.
But, these are not normal times. Inflation is not being caused by demand but by a lack of supply due to covid shutdowns, China limiting its shipments, etc. Raising rates will do nothing to fix this because demand is not causing the problem. In a few months inflation numbers will have easier comparisons versus last year, which by itself will bring inflation numbers down, and as covid (hopefully) continues to wain and supply channels and factories get back up to speed that will alleviate the supply problem, so between these two factors we could see inflation come WAY down over the next six months or so. That’s my take anyway.
So, bottom line and to answer your question directly, despite rates rising they are still extremely low by historical standards and the underlying economy is strong with historically low unemployment, so a 50bp hike here or their and the 10-year at 3.1% it’s unlikely the economy — and hence demand — will be affected to any significant degree and thus there’s no incentive or need for audio companies to lower their prices. And my bet is once inflation numbers come down for the reasons mentioned above the Fed will feel less pressure to raise further and long yields will moderate and possibly even come back down. Good question though.
