Ideas:
The Bank of Japan, usually is very conservative and doesn't want to upset the financial markets with any kind of action. Do no harm is a good way to describe how they do things compared to the US Federal Reserve, which increased the key rate a lot, which had a lot of side affects on the US economy, even though it might have helped to bring down inflation.
The Bank of Japan most likely is not going to increase the rate this fall, as they are watching the Japanese economy very carefully to see if it can get back on track and all economic indicators it watches are in line.
But if they do increase the rate, it might be no more than 0.25 percent like in July, as they don't want any real side affects that might cause harm to the Japanese economy.
The weak Japanese yen, maybe more than inflation is the real challenge for the Bank of Japan. But at the same time there are positives for a weak yen that can't be ignored and or course there are real negatives.
So the Bank of Japan has a find a balance between the positives and negatives of the weak Japanese yen.
Does the Bank of Japan continue with the weak yen or continue to let it be weak, as it helps Japanese exporters, and Japanese overseas investors, and it helps foreign tourists, as they can buy more in Japan.
But it hurts importers and the weak Japanese yen increases import prices, so the Bank of Japan has to decide what is best for the Japanese economy overall.
Most likely the rate increase is going to be the first month of the new year, but you never know as it could be in December if the Japanese economy improves enough for the Bank of Japan.
The Japanese economy just doesn't increase or grow that much, as maybe be described as stagnant for a very long time. So the Bank of li Japan has to be concerned about if and when the Japanese economy can get back to some kind of normalcy or sustained growth, even if the growth is only 1 percent.
The weak Japanese yen is causing some havoc among some sectors in the Japanese economy, but at the same time is a boom for some in the Japanese economy too.
Ask the hotels, restaurants, department stores and so on who mainly cater to foreign tourists if they like the weak Japanese yen.
Financial markets, globally, are just too sensitive about everything, and never take a long term view or a big picture view, as they only think about now and not tomorrow or next week or next month, or next year.
Many years, ago, for example, Japanese companies could make long term plans and if they had a not so good quarter it was not the end of the world as they were focused on the long time and not what happened in one specific quarter.
But these days, because more large Japanese companies have significant shareholders, and shareholders only care about today and don't see things long term, and as a result, many Japanese companies have scrapped long term plans and focus on quarter to quarter to please the shareholders.
Markets remain in a unstable position, not so much about what the BOJ has done but because, again, they are just too sensitive about everything, They are like "snow-flakes", and react to everything they don't like.
But the BOJ is in a no-win situation as anything they do the markets are going to react, whether some good for Japanese economy or something not so good, the financial markets don't care, they just want things their way, even though the BOJ tries to improves things.
Again, the BOJ seems to be more sensitive to the markets that the US Federal Reserve, who seems to be a little more detached from the markets while the BOJ seems to want to keep the markets calm more than the Federal Reserve.
The Bank of Japan doesn't really have any room to cut its rate as its rate is almost at zero or 0.25 percent, so it must increase the key rate to try and get Japanese yen back to where the US key rate is or the EU central bank is or the where the Bank of England is, but its going to take more rate increase, for example to reach the US rate of 3 to 5 percent or percentage points.
The BOJ has a long way to go, and remains to be seen how long, if ever, the BOJ will get the Japanese rate in line with other advanced economies, or if they even want to do it.
It take several years, if even that for the Japanese rate to be equal with the other advanced rates, but the BOJ just not want the rate to be equal, as the weak Japanese yen might have more positives for the Japanese economy than negatives as this time.
Again, the weak Japanese yen, has both positives and negatives, and yes, the BOJ might be leaning toward keeping the yen weak, but it might try to tweak it some to help importers ad inflation related to the weak Japanese yen, and have a more balances Japanese yen, if that is even possible.
The weak Japanese yen has brought to Japan record foreign tourists and the weak yen gives them more purchasing power, and of course helps the hotels, restaurants, and even the Japanese convenience stores where many foreign tourists go to.
So the BOJ of course sees all of this, but at the same time, there is a significant segment of the Japanese economy who never see foreign tourists or get any of the business, so the weak Japanese yen might not be good for them.
So, again, the BOJ has to find a balance that helps those who never see any business from foreign tourists, but feel the affects of the weak Japanese yen, and the record number or tourists that help many Japanese businesses in Japan.
Of course the Bank of Japan is going to say its concerned about the weak Japanese yen, but at the same time it knows, it helps a significant segment of the Japanese economy too.
The Bank of Japan is always going to say what it needs to say, and again, to appease the financial markets so that they don't get too upset about what they say or do.
Yes, inflation, for many in the Japanese economy is not good and should be controlled, as much as possible, bu there are just too many variables acting at the same time, for any central bank to control, especially the Bank of Japan.
The Bank of Japan might not do anything until the LDP election is finished as they don't want to interfere with anything that might have an affect on the election.
Even though it ended it negative rate policy in March, don't expect the BOJ to follow what other central banks do as they seem have their own strategies for how to manage and economy.
Even during the pandemic and after it really follow what the US Fed did as whenever the US Fed does something, the other central banks seems to follow.
Have a nice day!
