IMO, Fiat is monopoly money, going back and forth is also wrong. The higher the interest rate, the greater the inflation and if the interest rate is lowered, the inflation will remain the same, but the effect will be different. because it is the monopoly nature that refers to the fact that only the government has the authority to print or issue such fiat.
Because Inflation is a complex economic phenomenon that is influenced by many factors as well, including monetary policy, fiscal policy, demand and supply and external factors such as commodity prices. Inflation can also be affected by global events, such as fluctuations in world oil prices or changes in international trade policies. So, inflation occurs all over the world because there are factors that are interrelated and vary in each country. That's why inflation occurs all at once throughout the world.
I coincidentally saw your post here and read that you believe higher interest rates increase inflation, but do you understand why the FED increased interest rates significantly for a while now? Because higher interest rates incentivize people to
hoard their money instead of spending it, thereby removing it from circulation. Higher interest rates are supposed to
decrease inflation and that does not only count for daily purchases in the super market, but also to the real estate market. A hike in interest rates make it harder for people to borrow money, buy a house and repay the mortgage. Less mortgage-financed houses means less demand for houses, means house prices go down as less demand meets
more or less stable supply. I say more or less stable because I assume that the supply side is less elastic to interest changes than the demand side. I actually didn't check that, it is my assumption. But to summarize, increased interest rates are supposed to decrease inflation, not to increase it.
