How do central banks control exchange rates?
To strengthen the exchange rate, the central bank simply raises its policy interest rate. As investors in search of higher returns increase their demand for the currency, the exchange rate appreciates. By lowering interest rates, the central bank can weaken the exchange rate.

Central banks, especially those in developing countries, intervene in the foreign exchange market in order to build reserves for themselves or provide them to the country's banks. Their aim is often to stabilize the exchange rate.
Central banks conduct monetary policy by adjusting the supply of money, usually through buying or selling securities in the open market. Open market operations affect short-term interest rates, which in turn influence longer-term rates and economic activity.
The exchange rate is market-determined, with any official foreign exchange market intervention aimed at moderating the rate of change and preventing undue fluctuations in the exchange rate, rather than at establishing a level for it.
Typically, central banks intervene to avoid substantial and quick changes in the value of their currencies. This guarantees that they are neither undervalued nor overpriced for an inordinately long length of time.
The central bank must intervene in the foreign exchange market to hold the exchange rate fixed in the face of this excess supply: the bank sells foreign assets and buys money until the excess supply of money has been eliminated.
The Fed's network of standing swap lines with major central banks has been in place since 2013. It permits any of the six central banks to borrow any of the currencies of the other central banks in exchange for its own currency as collateral (dollars/euros/yen/Swiss francs/pounds sterling/Canadian dollars).
In a managed-floating system, the central monetary authority of countries influences the movement of the exchange rate through active intervention in the forex market with no preannounced path for the exchange rate. Examples include China, India, Russia, and Singapore.
Over a few weeks in the spring of 2023, multiple high-profile regional banks suddenly collapsed: Silicon Valley Bank (SVB), Signature Bank, and First Republic Bank. These banks weren't limited to one geographic area, and there wasn't one single reason behind their failures.
Why does the Fed attempt to influence the exchange rate?
Central banks may buy or sell foreign exchange for a number of reasons. They may “lean against the wind” of short-run fluctuations in exchange rates in order to promote “orderly market conditions,” or lean against the wind of longer-term movements in attempts to influence trendlike appreciations or depreciations.

In order to make a profit, banks and other money changers use different rates for buying and selling currency. The online rates you see are probably mid-rates - half-way between the buying and selling rates. Of course, just to be on the safe side, banks also charge commission on the transaction...
Interbank rates, also commonly referred to as market rates, are the official live conversion rates for a given currency pair. The interbank rate is the constantly fluctuating price at which banks trade currencies with each other.
In most cases they do so not out of any inherent preference for one interest rate level versus another, but as a means to influence dimensions of macroeconomic activity like prices and inflation, output and employment, or sometimes designated monetary aggregates.
The Fed, like all central banks, uses interest rates to manage the macroeconomy. Raising rates makes borrowing more expensive and slows down economic growth while cutting rates encourages borrowing and investment on cheaper credit.
Extreme short-term moves can result in intervention by central banks, even in a floating rate environment. Because of this, while most major global currencies are considered floating, central banks and governments may step in if a nation's currency becomes too high or too low.
A fixed exchange rate helps to ensure the smooth flow of money from one country to another. It helps smaller and less developed countries to attract foreign investment.
The disadvantages of a fixed exchange rate include:
Preventing adjustments for currencies that become under- or over-valued. Limiting the extent to which central banks can adjust interest rates for economic growth. Requiring a large pool of reserves to support the currency if it comes under pressure.
What happens when central bank buys its own currency?
If the central bank purchases domestic currency by selling foreign assets, the money supply shrinks because it has removed domestic currency from the market. This is an example of a sterilized policy.
