What Is the Interbank Market?

Let me explain the interbank market directly to you: it's a global network that financial institutions use to trade currencies and other currency derivatives straight between themselves. Some of this trading happens on behalf of big customers, but most of it is proprietary, meaning it's done for the banks' own accounts.

You see, banks worldwide rely on the interbank market to handle their exchange rate and interest rate risks, and they also use it to take speculative positions based on their research. This market is part of the larger interdealer market, which is an over-the-counter venue where institutions trade various asset classes among each other and for clients, often through interdealer brokers.

Key Takeaways

  • The interbank market is a global network used by financial institutions to trade currencies and other currency derivatives directly between themselves.
  • Banks use the interbank market to manage their own exchange rate and interest rate risk.
  • They can also use the market to take speculative positions based on research.
  • Most transactions within the interbank network are for a short duration, anywhere from overnight to six months.

Understanding the Interbank Market

When you look at the interbank market for foreign exchange, or forex, it handles commercial currency investments along with a lot of speculative, short-term trading. Transactions here typically mature overnight or up to six months.

This forex interdealer market features large transaction sizes and tight bid-ask spreads. You can have speculative trades aimed purely at profiting from currency movements, or trades for hedging exposure. Some are proprietary, but to a lesser extent, they're driven by corporate clients like exporters and importers.

History of the Interbank Forex Market

The interbank forex market came about after the Bretton Woods agreement collapsed and President Richard Nixon took the U.S. off the gold standard in 1971.

At that point, currency rates for most major industrialized nations started floating freely, with occasional government intervention. There's no central location for this market; trading happens simultaneously worldwide and only pauses for weekends and holidays.

This floating rate system emerged alongside low-cost computers that enabled fast global trading. In the early days, voice brokers matched buyers and sellers over phones, but computerized systems replaced them, scanning traders for the best prices.

Important Fact on Trading Systems

You should note that trading systems from Reuters and Bloomberg let banks trade billions of dollars at once, with daily volumes exceeding $6 trillion on the busiest days.

Participants in the Interbank Market

To be an interbank market maker, a bank has to be willing to make prices to others and ask for prices. Deals here can exceed $1 billion in one go.

In the U.S., big players include Citicorp and JP Morgan Chase. Globally, Deutsche Bank in Germany and HSBC in Asia are major ones. Other participants like trading firms and hedge funds influence exchange rates through their operations, but large banks have the biggest impact.

Credit and Settlement Within the Interbank Market

Most spot transactions settle two business days after execution, known as T+2, except for U.S. dollar versus Canadian dollar, which settles the next day. Banks need credit lines with counterparts even for spot trades.

Many banks use netting agreements to offset transactions in the same currency pair settling on the same date with the same counterpart. This cuts down settlement risk by reducing the actual money transferred and the overall risk.

What Is a Bid-Ask Spread?

Let me clarify for you: the bid-ask spread is the difference between the bid price and the ask price, where the bid is usually lower.

What Is a Market Maker?

Market makers handle stock transactions at any time on a continuous basis, providing bid/ask spreads to keep the market liquid.

What Is a Spot Transaction?

A spot transaction involves selling or buying a commodity or currency for immediate delivery, typically within two business days, though the exact timing can vary by market.

The Bottom Line

The interbank market is decentralized and unregulated, but central banks gather data from participants to check for economic impacts. It's crucial to monitor this market because issues here can directly affect overall economic stability.

Over time, brokers connecting banks for trades have become a key part of the interbank ecosystem.
