How Did STP Come About?

STP emerged in the 1990s within the financial sector, where increasingly higher volumes of trades demanded efficiency.

Before STP, each trade involved multiple manual handoffs, leading to delays, errors, and increased costs.

STP revolutionized this process by introducing automated workflows, reducing reliance on human input.


Why Does STP Matter?

STP is important for various operations, including:

Trade Execution

STP allows near-instantaneous trade processing, which helps with market liquidity.


It automates the clearing and settlement process, reducing counterparty risk.

Regulatory Compliance

STP helps financial institutions adhere to stringent reporting requirements.

STP Beyond Finance

Beyond finance, STP extends to other industries like healthcare (claims processing) and insurance (policy management).

Its core principles of automation and efficiency are valuable wherever data-driven processes exist.


STP Key Facts & Statistics

STP has become increasingly prevalent in securities trading for automated and seamless transactions without manual intervention. 

Here are some key points and statistics about STP in securities trading:

  • Nearly all secondary market securities trading today involves electronic processing and STP for trade settlements.
  • Financial service companies have dedicated back-office staff responsible for managing the high volume of trade settlements facilitated by STP.
  • The Nasdaq, launched in 1971, was the first fully electronic stock exchange enabling STP.
  • STP has significantly reduced settlement times.
    • In 2017, the SEC mandated a T+2 (trade date plus 2 days) settlement cycle for securities trades, which STP makes possible.
    • This shifted to T+1 on May 28, 2024.
  • Efficient STP processes can lead to higher securities lending utilization rates.
    • Fidelity Agency Lending’s program “consistently ranks in the top quartile for the market value of automated US equity trades” due to its STP capabilities.
  • Fidelity’s securities lending cash collateral holdings grew 108% from 2019 to 2022, attributed partly to its investments in STP and post-trade efficiency for client revenue generation.
  • 44% of agent lenders cited STP and post-trade as immediate technology objectives to reduce costs and support revenue.


Components of STP

Data Standardization

STP requires standardized formats for data (like trade details, customer information, etc.) across all systems involved.

System Integration

Different systems need to integrate with each other seamlessly.

This means integrating trading platforms, risk management systems, clearinghouses, and more.

It’s like connecting all the pipes in a plumbing system – everything needs to flow smoothly.

Automated Workflows

The real magic of STP is automation.

We define specific rules and triggers that automatically move transactions through each step of the process, from order entry to settlement.

This eliminates manual handoffs and speeds things up significantly.

Exception Management

Not everything can be automated.

There will be errors or unusual situations.

STP systems need built-in mechanisms to flag these exceptions for human review and resolution.

Think of it like a quality control checkpoint in a factory.

Technology Infrastructure

The backbone of STP is technology.

This includes:

  • high-performance networks
  • secure databases, and
  • reliable processing power

These make sure that the STP engine runs smoothly, even during peak trading volumes.

Real-Time Processing

STP works best when transactions are processed in real-time or near real-time.

This means minimal lag time between steps, which is important for fast-paced markets like stocks or foreign exchange.

These components work together, transforming complex financial transactions into smooth, efficient processes.


Benefits of Implementing STP

Speed and Efficiency

This is the big one. STP drastically reduces transaction times.

We’re talking about completing processes in minutes or even seconds, compared to hours or days with manual methods.

This faster turnaround means improved customer service, increased market responsiveness, and better utilization of resources.

Reduced Risk

Manual processes are prone to errors – typos, miscalculations, missed steps.

STP takes the human element out of the equation for these tasks that are straightforward and automatable, minimizing the chance of these costly mistakes.

It also helps enforce compliance with regulations, as automated systems follow pre-defined rules consistently.

Cost Savings

STP isn’t just about speed but saving money.

By automating tasks, it reduces the need for manual labor, freeing up staff for more creative, strategic, and higher value-add activities.

Fewer errors also mean lower costs associated with fixing mistakes and dealing with unhappy customers.

Plus, streamlined processes often lead to better use of capital and improved cash flow.

Enhanced Transparency

STP creates a clear audit trail for every transaction.

This means we know exactly who did what and when, making it easier to track down issues, resolve disputes, and demonstrate compliance.

It’s like having a built-in surveillance system for your data.


As your business grows, STP can easily handle increased volumes without a proportional increase in costs.

This makes it a cost-effective solution for both small and large organizations.


Overall, STP isn’t just a nice-to-have, it’s a competitive advantage.

It allows businesses to operate faster, smarter, and with less risk. 


Challenges & Considerations of STP

Integration Headaches

Getting different systems to work together isn’t always easy.

We often encounter legacy systems that weren’t designed with STP in mind.

These may use outdated technology or proprietary formats, making integration a complex and time-consuming process.

Data Quality Nightmares

Garbage in, garbage out. STP relies on accurate, consistent data.

If the source data is messy or incomplete, it can throw a wrench in the entire process, leading to errors and delays.

There needs to be robust data validation and cleaning mechanisms for a smooth STP flow.

Regulatory Maze

Financial regulations are constantly evolving, and STP systems need to keep up.

This means regular updates and modifications to ensure compliance with reporting requirements, risk management rules, and other legal obligations.

It’s like navigating a constantly changing obstacle course.

Operational Risks

While STP reduces many operational risks, it introduces new ones.

System failures, cyberattacks, or even simple software bugs can disrupt the entire process.

Backup plans, redundancy measures, and disaster recovery procedures are necessary to reduce these risks.

Cost and Complexity

Implementing STP requires a significant investment in technology, infrastructure, and expertise.

It’s not a small undertaking, especially for smaller organizations.

The costs and benefits have to be weighed to be sure that STP makes financial sense for the business.
