Maybe, maybe not.
Interest rates don't rise or fall automatically: the BoE looks at the state of the country and the world and decides how to adjust interest rates to best achieve a healthy financial state (e.g. 2% inflation, no more, no less).
e.g. if you raise interest rates, people tend to have less spending money so buy less, so inflation goes down. If you drop interest rates, the opposite happens.
However, this week is different.
The pound dropped in value because the markets (that buy and sell currency) lost faith in its long term value so everyone started to sell pounds off.
As the pound dropped, the value of government bonds dropped which led to institutions selling them off. This is because bonds are valued in pounds. So a £100 bond might be worth $150 one day but only $100 the next, if the pound loses value to the dollar.
A glut of bonds for sale, dropped the value even futher. The BoE was worried about them spiralling down in value which would wipe out people's pensions (because one of the key buyers of bonds is pension schemes).
So they are likely to put interest UP. That makes the bonds more valuable because they pay dividends at a higher interest rate. Which stops people selling them. The BoE also started to buy those bonds themselves, to take them off the market and try and bolster the value that way (e.g. less available to buy = higher price).
If the government reverse their decision, that does not automatically mean the market will start buying pounds again. It make look at the shit show and think: I'm better off not bothering with pounds until I can be sure the value will remain stable again.
If the pound doesn't rise in value, bonds don't rise in value, people stop buying them (and start selling them) and interest rates have to stay high to make bond investment look tempting.
At least that's how I understand it. But I have no qualifications other than an interest....
