Banks and their AI-driven trading systems are highly sophisticated, but there are certain situations where they cannot manipulate the market and have to follow or “obey” market conditions due to the sheer scale and external forces involved. Here are a few such situations:
### 1. **Major Geopolitical Events**
Geopolitical events like wars, natural disasters, or major political upheavals (e.g., Brexit or US-China trade tensions) create volatility that is too unpredictable and widespread for banks to control. In these instances, the sheer volume of market participants reacting in real time overwhelms any manipulation attempts. The AI-driven algorithms would instead focus on reacting to and adjusting strategies based on market movements rather than trying to steer them.
**Example**: During the Brexit vote, the pound’s price plummeted in ways that were beyond any institution's ability to control or manipulate because of the enormity and unpredictability of the event.
### 2. **Central Bank Interventions**
When central banks intervene in the market (through **interest rate changes**, **quantitative easing**, or direct currency interventions), these actions influence the forex market in a manner that cannot be counteracted or manipulated by individual banks. AI systems at banks must adapt to these moves, not fight against them.
**Example**: In 2015, the Swiss National Bank (SNB) removed its currency peg with the euro, causing a massive and sudden appreciation of the Swiss franc. This type of central bank intervention was too large and abrupt for banks to manipulate, forcing them to react rather than control.
### 3. **Market Sentiment and Mass Retail Activity**
At times, overwhelming retail trader sentiment or institutional investor movements can be too large to manipulate. For example, during times of **mass retail trading frenzy** (e.g., social media-driven movements like the GameStop/Reddit trading events in 2021), markets can move in unpredictable directions, and banks are forced to adapt rather than try to steer the entire market.
**Example**: A large-scale retail sentiment shift might occur if retail traders flood into the market during a specific news event, changing price action faster than banks can anticipate or manipulate.
### 4. **High-Liquidity Markets and Major Currency Pairs**
In **highly liquid markets**, such as the USD/EUR or USD/JPY pairs, it becomes difficult for any single entity, even large banks, to manipulate price movements. The volume of transactions and diversity of participants means that the market is too large to influence significantly.
**Example**: Even the biggest players cannot easily manipulate currency pairs like the EUR/USD because of the volume of trade and the number of participants from around the world, from retail traders to hedge funds and governments.
### 5. **Global Financial Crises**
During systemic financial crises, such as the 2008 financial meltdown, the market becomes so volatile and driven by fear that no single entity can control the market's direction. Banks, along with other institutions, are forced to adapt to chaotic conditions rather than exert influence.
**Example**: In 2008, the collapse of Lehman Brothers and the ensuing financial crisis caused massive, uncontrollable swings in currencies and other assets. The AI systems in banks would have focused on damage control and mitigating losses rather than manipulating the market.
### 6. **Regulatory and Legal Constraints**
Banks operate under **regulatory frameworks** that prevent certain types of market manipulation. Governments and regulatory bodies monitor large-scale trading activities, and if banks are found to engage in illegal practices like market manipulation or collusion, they face significant fines or legal action. AI systems must work within these constraints, meaning they cannot manipulate markets in ways that violate regulations.
**Example**: Many banks have faced lawsuits and regulatory penalties for attempting to manipulate currency benchmarks like LIBOR or forex rates. These fines and legal actions discourage future attempts at direct manipulation.
### 7. **Liquidity Crises or Lack of Counterparties**
In certain situations, especially during liquidity crunches, there may not be enough counterparties to execute trades. In these cases, even large banks have to wait for suitable liquidity or market conditions to execute their strategies. Trying to manipulate prices during a liquidity crisis could backfire, as thin markets can lead to outsized price moves that even the banks cannot control.
**Example**: During sudden liquidity shortages, price gaps can occur, and banks may have to hold off trading or be forced to take trades at suboptimal prices. In these situations, manipulation becomes impractical or risky.
---
### Conclusion:
Banks and their AI systems, while powerful, cannot always manipulate the market. They must respect certain conditions, including macroeconomic forces, central bank actions, high liquidity markets, and regulatory environments. In these scenarios, even the most sophisticated trading algorithms have to adapt to the market rather than trying to control it.
