You will not have to worry about higher interest rates for a while. If the rates go up then the national debt can not be paid, not even the interest rates on their huge loans. Government wants to increase the interest rate so they have a "tool" to use to control the market. At the moment that tool is unusable due to historically low interest rates. But they are stuck in a corner. They tried to raise the interest rates in Dec and the stock market tanked in January. What probably stopped that crash from going further was company owners and government buying back stocks to stop pricing to drop further. They will not be brave enough to try to hike the rates unless they are prepared for a crash.
In Europe the interest rates are negative and that has never happened before so there are no way of telling how that will turn out exactly.
Normally fusing the economy with "free" money that the low interest rates leads to, would spark the economy to do better but it has the opposite effect because the "free" money is not going to where it is needed. It goes to the people who already have money/the investors. These people will not spend the money, they will invest it. So that is why we see a uppgoing stock- and real estate market. That leads to pumped up pricing i.e. bubble.
What would work is to give money to people who does not have any. They will spend the money. So if the well fare system or increase the pensions then that money will be spent, and consumption would go up. They would not invest it in stocks or real estate. But that is a socialist way of looking at it and it will not be accepted by a capitalist country like USA.
The government are ready for another round of quantative easing (printing money). That would lead to a bigger bubble and only kicking the can down the road (moving the problem ahead/not dealing with the real issue). Some people are talking about helicopter money and that would actually be a better solution because some of the money will end up in the hands of people who needs the money for consumption. But some of it won´t. So best is to put the money in the hands of people who has nothing. They will buy diapers for their kids, new tires, pay bills etc. That will lead to new jobs etc etc.
In Sweden for instance they could increase the interest rates but the economy is more of a macro- than a micro economy so Sweden can not act on it´s own like they could years ago. If a single country has much higher interest rates then that will lead higher costs for investments and lead to higher product costs and lead to worse economy due to lower comparable rates in other countries. So the countries can not act on it´s own and are depending on the rest of the worlds economy. Same for USA if they like to start an increase.
Historically USA triggered a better economy by using debt to get production and economy to rise. But debt is a loan that has to be paid back. When it is owed for a longer time that debt is becoming a burden and that is what is happening all over the world. So almost everyone is in debt.
It is like when you can use your credit card to get something temporarily. But when you use multiple credit cards and they are not paid back quickly you feel tied down instead. Same scenario with national debts that are high for a longer time. It acts as surpressing instead of new opportunities for the economy.
So this crash is kind of needed in order to start from the beginning with real growth not based on debt. The problem is now not being solved only postponed until no one can do anything to stop it from crashing down.
China is a country who lend money or invested in USA but they can not get their money back quickly. If they did ask for a majority of it back they would exchange it for yen and that would lead to a dramatically low dollar and their remaining money they lend USA will decrease in value due to a huge off sell in dollar to yen so the dollar will be decreased dramatically. So China will not be able to ask for their money back any time soon.
So everyone is stuck in a corner until it all comes crashing down and that is when real growth can happen without the help of global debt.
So my conclusion is...the interest rates will not possibly going up until the big crash has happened
