The reason is due to the oil shocks.
As stated in a comment below:

While lots of things contributed, this is almost certainly the case. Energy is an input into everything. Our current standard of living exists mainly due to energy and figuring out productive/efficient ways to consume energy.
For example if we retained all of our knowledge, all of our productive know how, but were banned from using fossil fuels and electricity we'd be essentially back to pre-industrial standards of living. When you think about it, it's self-evident, but we can't do anything modern without consuming enormous amounts of energy. Transportation, shipping, computing, agriculture, communication, heating manufacturing all of these are essentially energy consumption endeavors.
More expensive energy means all of these factors because significantly more expensive. The cost of your food goes up if every input is now paying more for energy. If maintaining a standard of living is now more expensive then cost of labor goes up without any improvement in standard of living. This drives inflation. Increasing the price of energy probably is likely a more broad economic driver of inflation than lowering interest rates. Lowering interest rates drives asset price increases heavily, but much less so on commodity and day to day price increases. Eventually those asset price increases work their way back to housing and then drive labor, but it's not very direct. Increasing the cost of energy drives up the price of everything. The only thing that tops it is direct giving of money to people.
The 1970s oil shocks cost us an enormous amount in our standard of living and drove pure inflation. Just like the oil price increases of the past few years (along with supply/labor shortages) drove our recent bout of inflation. Oil dropped in early 2020 and so did inflation. Oil peaked in mid 2022 and so did inflation. Energy prices drive your economy - anything that notably increases the cost of energy will have ripple effects on the rest your economy.
