When someone buys 1000 lots of treasury bond futures contracts, the interest rate starts to rise the next day and remains until the contract expires. Why did it lead to the purchase of the state treasury? The rise of interest rate depends on the bonds of the central bank, and it will fall because it depends on the flow of hot money in the market. When the interest rate rises, the supply of RMB exceeds demand, which means that bonds will depreciate, and RMB depreciation will bring CPI, which is also to reduce the circulation of hot money in the market, so that most people can choose to buy bonds or save as a whole and reduce speculation. Reduce inflation by controlling domestic demand.

So when interest rates rise, bonds will fall and supply will be greater than.

If the interest rate falls, the bonds will be all. This is the shortage of supply.

Of course, the rise and fall of interest rates depends on many aspects and factors.
