Fixed exchange rate system in the context of "Silver standard"

Monetary policy is the policy adopted by the monetary authority of a nation to affect monetary and other financial conditions to accomplish broader objectives like high employment and price stability (normally interpreted as a low and stable rate of inflation). Further purposes of a monetary policy may be to contribute to economic stability or to maintain predictable exchange rates with other currencies. Today most central banks in developed countries conduct their monetary policy within an inflation targeting framework, whereas the monetary policies of most developing countries' central banks target some kind of a fixed exchange rate system. A third monetary policy strategy, targeting the money supply, was widely followed during the 1980s, but has diminished in popularity since then, though it is still the official strategy in a number of emerging economies.

The tools of monetary policy vary from central bank to central bank, depending on the country's stage of development, institutional structure, tradition and political system. Interest-rate targeting is generally the primary tool, being obtained either directly via administratively changing the central bank's own interest rates or indirectly via open market operations. Interest rates affect general economic activity and consequently employment and inflation via a number of different channels, known collectively as the monetary transmission mechanism, and are also an important determinant of the exchange rate. Other policy tools include communication strategies like forward guidance and in some countries the setting of reserve requirements. Monetary policy is often referred to as being either expansionary (lowering rates, stimulating economic activity and consequently employment and inflation) or contractionary (dampening economic activity, hence decreasing employment and inflation).

The Eastern Caribbean dollar (symbol: EC$; code: XCD) is the currency of all seven full members and one associate member of the Organisation of Eastern Caribbean States (OECS). The successor to the British West Indies dollar, it has existed since 1965, and it is normally abbreviated with the dollar sign $ or, alternatively, EC$ to distinguish it from other dollar-denominated currencies. The EC$ is subdivided into 100 cents. It has been pegged to the United States dollar since 7 July 1976, at the exchange rate of US$1 = EC$2.70.

In macroeconomics, an open market operation (OMO) is an activity by a central bank to exchange liquidity in its currency with a bank or a group of banks. The central bank can either transact government bonds and other financial assets in the open market or enter into a repurchase agreement or secured lending transaction with a commercial bank. The latter option, often preferred by central banks, involves them making fixed period deposits at commercial banks with the security of eligible assets as collateral.

Central banks regularly use OMOs as one of their tools for implementing monetary policy. A frequent aim of open market operations is — aside from supplying commercial banks with liquidity and sometimes taking surplus liquidity from commercial banks — to influence the short-term interest rate. Open market operations have become less prominent in this respect since the 2008 financial crisis, however, as many central banks have changed their monetary policy implementation to a so-called floor system (or system of ample reserves), in which there is abundant liquidity in the payments system. In that situation central banks no longer need to fine tune the supply of reserves to meet demand, implying that they may conduct OMOs less frequently. For countries operating under an exchange rate anchor, direct intervention in the foreign exchange market, which is a specific type of open market operations, may be an important tool to maintain the desired exchange rate.

In public finance, a currency board is a mechanism by which a monetary authority is required to maintain a fixed exchange rate with a foreign currency by fully backing the commitment with foreign holdings, or reserves. This policy objective requires the conventional objectives of a central bank to be subordinated to the exchange rate target.

Although a currency board is a common (and simple) way of maintaining a fixed exchange rate, it is not the only way. Countries often keep exchange rates within a narrow band by regulating balance of payments through various capital controls, or though international agreements, among other methods. Thus, a rough peg may be maintained without a currency board.

A currency band is a range of values for the exchange rate for a country’s currency which the country’s central bank acts to keep the exchange rate within.

The central bank selects a range, or "band", of values at which to set their currency, and will intervene in the market or return to a fixed exchange rate if the value of their currency shifts outside this band. This allows for some revaluation, but tends to stabilize the currency's value within the band. In this sense, it is a compromise between a fixed (or "pegged") exchange rate and a floating exchange rate.
