Repo Rate is the interest rate for short-term loans secured by securities issued by the Bank of England. This is the major rate in the UK. The Bank of England has set an upper threshold of inflation at 2%; if consumer prices are rising faster than 2%, then increase of rates is high probable.
High interest rates reduce the growth of consumer lending and stimulate the growth of savings, which leads to slower economic growth. The growth of rates usually leads to an increase in capital inflows and the growth of the national currency in the medium term, however, if growth rates are not based on high rates of economic growth, it could lead to economic stagnation and negative impact on the currency markets in the long term.
