Also laws of supply and demand. Since the supply chain is broken or cracked, businesses, mainly manufactures are forced to cut back on production so resources aren't unnecessarily wasted and to prevent excess unused inventory. In order to keep what inventory is at the store, the price has to be raised so the existing sale inventory isn't gone too quickly.
When it comes to oil, I found out yesterday that while drilling companies have the leases to build oil rigs they do not have the leases to drill. Biden is NOT handing out drilling leases/permits.
