Managed float regimes, otherwise known as dirty floats, are where exchange rates fluctuate from day to day and central banks attempt to influence their countries' exchange rates by buying and selling currencies. Almost all currencies are managed since central banks or governments intervene to influence the value of their currencies. So when a country claims to have a floating currency, it most likely exists as a managed float.
How a Managed Float Exchange Rate Works
Generally, the central bank will set a range which its currency's value may freely float between. If the currency drops below the range's floor or grows beyond the range's ceiling, the central bank takes action to bring the currency's value back within range .
India
India has a managed float exchange regime. The rupee is allowed to fluctuate with the market within a set range before the central bank will intervene.
Management by the central bank generally takes the form of buying or selling large lots of its currency in order to provide price support or resistance. For example, if a currency is valued above its range, the central bank will sell some of its currency it has in reserve. By putting more of its currency in circulation, the central bank will decrease the currency's value.
Why Do Countries Choose a Managed Float
Some economists believe that in most circumstances floating exchange rates are preferable to fixed exchange rates. Floating exchange rates automatically adjust to economic circumstances and allow a country to dampen the impact of shocks and foreign business cycles. This ultimately preempts the possibility of having a balance of payments crisis. A floating exchange rate also allows the country's monetary policy to be freed up to pursue other goals, such as stabilizing the country's employment or prices.
However, pure floating exchange rates pose some threats. A floating exchange rate is not as stable as a fixed exchange rate. If a currency floats, there could be rapid appreciation or depreciation of value. This could harm the country's imports and exports. If the currency's value increases too drastically, the country's exports could become too costly which would harm the country's employment rates. If the currency's value decreases too drastically, the country may not be able to afford crucial imports.
This is why a managed float is so appealing. A country can obtain the benefits of a free floating system but still has the option to intervene and minimize the risks associated with a free floating currency. If a currency's value increases or decreases too rapidly, the central bank can intervene and minimize any harmful effects that might result from the radical fluctuation.
