weecalf: "Just humour me here as I don’t understand .This happens that happens okay but why does that mean companies that have nothing to do with the running of the country are allowed to raise mortgage rates acause goverment are borrowing more money . " - well you have 2 things there, government borrowing and interest rates. I assume the main thrust is interest rates so I'll concentrate on those. By companies I assume you mean lenders. Lenders are mostly lending someone else's money, money they borrowed directly or money they have on deposit from savers. If interest rates rise then they have to pay more for their borrowings from whatever source, they are just passing it on. The base rate effects everyone because the BOE actually lends to banks all the time for various reasons so every other bank must inevitably follow suit, right down the line to the consumer. Think of it like a potato, if the farmer increases the price then so must everyone until finally the chip shop puts up the price of a bag of chips.
