Interbank Market

The base for currency transactions between large privately held banks

What is the Interbank Market?

As the name suggests, the interbank market is a market where foreign currency is traded between large privately held banks. The interbank market is what people refer to when talking about the currency market. It is built of large currency trades above $1 million, e.g., CAD/USD or USD/JPY. However, the transactions are often much larger, upwards of $100 million and beyond, and occur in just seconds.

 

Interbank Market

 

Each trade comes with a previously agreed-upon amount and rate for both parties. Some of the exchanges taking place are banks working on behalf of their clients. Many of the other transactions are proprietary, meaning the trades are for the banks’ own accounts. It helps regulate the bank’s interest rate and exchange rate risks.

The interbank market follows a floating rate system, meaning the exchange rate “floats” or adjusts on its own time based on the supply and demand of currency trades. It is also an unregulated and decentralized system, meaning there is no specific location where these transactions occur, unlike trading securities that have exchanges like the New York Stock Exchange (NYSE).

 

Settlements and Trade Agreements

Trades in the interbank market are often referred to as taking place in the spot market or cash market. For the most part, the currency transactions settle in two business days; one of the major exceptions is the US dollar to Canadian dollar transactions that settle in one business day.

As a result of the delay in settlement, financial institutions need to acquire credit with their trade partners to facilitate the trades. The settlement delays increase the risk of the transaction, which are then countered by netting agreements between the banks.

When the currencies are traded, there are two different prices: the bid price and the ask price. The bid price is the value you would pay to buy the currency. The ask price is the value you like to receive if you are selling the currency. The practice is extremely similar to the way securities are traded on the market.

The difference between the bid and ask price is called the “bid to ask spread.” The spread is the transaction cost, minus any commissions or broker fees associated with the trade.

Market makers set the bid-ask spread. The market makers consist of the largest banks in the world. The banks constantly trade currency between each other for themselves or on behalf of their customers. The trades form the fundamental base for the currency exchange rates/market. As a result of the banks’ competitiveness, the market ensures a fair and close spread.

 

Regulation of the Interbank Market

As was previously stated, the interbank market is unregulated and decentralized. With that in mind, there is no specific location or exchange that the currency is traded on; instead, it is composed of thousands of interbank exchanges of currency at agreed-upon prices and quantities. The prices come from market makers, usually the largest banks in the world.

Central banks in many countries release spot-close prices that reflect the previously stated market makers’ prices at the end of each day. In some countries, there are national or local banking regulations in which currency traders must follow.

For example, many national authorities or central banks regulate foreign currency options; however, only a small part of the trades takes place on exchanges such as the Chicago Mercantile Exchange or the International Securities Exchange.

The interbank market is an essential aspect of the foreign exchange market. It is where the majority of large-scale currency transactions take place and is predominantly used for trades among bankers and their large clients.

The interbank market consist of four main components:

  • The spot market, which entails transactions made for the currency price at the exact time of the trade.
  • The forward market, which is an agreement to exchange currency at an agreed-upon future date and price.
  • swap trade, which is a combination of both spot and forward. The banker buys the currency at the spot market current price and then sells the equivalent amount in the forward market at a future date and price.
  • Some banks also participate in the SWIFT (Society for Worldwide Interbank Financial Telecommunications) market. SWIFT enables institutions to send and receive information regarding financial transactions in a safe, proven, and reliable way.

 

Summary

In summary, the interbank market is made up of large-scale currency transactions between banks around the world. The transactions can be proprietary, taking place on behalf of the bank’s accounts or on behalf of the bank’s customers.

The interbank market is the predominant influence on the exchange rates around the world in the short term. Most transactions take two business days to settle, with a few exceptions. As a result of the settlement delay, a credit between the companies/banks is established to help bring the trades to fruition.

The interbank market is non-regulated, with minor exceptions on the national and local levels in some places.
