0. 1 percentage point. The basis point is defined as "0.00 1(0.0 1%)" or "100% of one percentage point". Widely used in calculating interest rates, exchange rates, stock prices and other fields, because these fields need to involve a very small percentage of calculation. The basis point is the gap between the spot price and the futures price of a commodity, that is, the gap between the current price and the futures price. Because support costs need to be paid, the basis point is usually negative. Generally speaking, the spot price is actually lower than the nearby futures price. As the delivery date approaches, the holding cost decreases and the spread between spot and futures narrows. The financial industry usually uses the basis point to indicate the interest rate change of financial instruments or the difference between two kinds of interest rates (including fixed income securities), so 10 basis point = 10× 0.0/= 0. 1, so10 basis point is 0./kloc-0.
