为什么央行以微小幅度调整利率

Central banks rarely change interest rates by more than 0.25 percentage points at once.
Small adjustments help avoid sudden shocks to borrowing costs for households and businesses.
Markets expect gradual moves, so abrupt changes could trigger volatility in bond and stock prices.
Policymakers use tiny increments to test how the economy responds before committing further.
Even a 0.10% shift affects billions in mortgage and corporate loan payments nationwide.
Gradualism also allows time for data collection, since economic trends take months to confirm.
It reflects humility: central banks acknowledge uncertainty in forecasting inflation or growth.
Sudden large cuts might spark inflation fears, while steep hikes could stall employment gains.
This cautionary rhythm balances speed of response with stability of expectations.
Thus, monetary policy works less like a switch and more like a finely tuned dial.
