'''Financial engineering''' is a multidisciplinary field involving [[financial theory]], methods of [[engineering]], tools of [[mathematics]] and the practice of [[Mathematical programming|programming]].<ref name="IEOR">{{cite web|url=http://ieor.columbia.edu/ms-financial-engineering|title=MS in Financial Engineering|publisher=Columbia University Department of Industrial Engineering and Operations Research|access-date=2017-01-18|archive-url=https://web.archive.org/web/20170119053357/http://ieor.columbia.edu/ms-financial-engineering|archive-date=2017-01-19|url-status=live}}</ref> It has also been defined as the application of technical methods, especially from [[mathematical finance]] and [[computational finance]], in the practice of [[finance]].<ref name=Beder>Tanya S. Beder and Cara M. Marshall, ''Financial Engineering: The Evolution of a Profession'', Wiley (June 7, 2011) 978-0470455814</ref>

Financial engineering plays a key role in a bank's [[Investment banking#Sales and trading|customer-driven derivatives business]]<ref>Qu, Dong (2016). ''[https://www.amazon.com/gp/product/1118632621?keywords=dong%20qu&qid=1444725736&ref_=sr_1_2&sr=8-2 Manufacturing and Managing Customer-Driven Derivatives]''.

— delivering bespoke [[Over-the-counter (finance)#Contracts|OTC-contracts]] and [[exotic derivative|"exotics"]], and implementing various [[structured products]] — 
which encompasses quantitative modelling, quantitative programming and [[risk management|risk managing]] financial products in compliance with the regulations and [[Basel Accords|Basel]] capital/liquidity requirements.

An older use of the term "financial engineering" that is less common today is aggressive restructuring of corporate [[balance sheet]]s.{{citation needed|date=June 2023}} 
Mathematical finance is the application of [[mathematics]] to finance.<ref name="Dubil" /> Computational finance and mathematical finance are both subfields of financial engineering.{{citation needed|date=October 2019}} Computational finance is a field in computer science and deals with the data and algorithms that arise in financial modeling.

==Discipline==
Financial engineering draws on tools from [[applied mathematics]], [[computer science]], [[statistics]] and [[economic theory]].<ref name=IAFE>{{cite web|url=http://www.iafeguide.org/financial-engineer.php|title=What is Financial Engineering?|publisher=International Association of Financial Engineers|access-date=2012-07-22|archive-url=https://web.archive.org/web/20120630202827/http://www.iafeguide.org/financial-engineer.php|archive-date=2012-06-30|url-status=dead}}</ref>
In the broadest sense, anyone who uses technical tools in finance could be called a financial engineer, for example any [[computer programmer]] in a [[bank]] or any [[statistician]] in a government economic bureau.<ref>Ali N. Akansu and Mustafa U. Torun. (2015), A Primer for Financial Engineering: Financial Signal Processing and Electronic Trading, Boston, MA: Academic Press, {{ISBN|978-0-12-801561-2}}</ref> However, most practitioners restrict the term to someone educated in the full range of tools of modern finance and whose work is informed by financial theory.<ref name=Neftci>Salih N. Neftci, ''Principles of Financial Engineering'', Academic Press (December 15, 2008) 978-0123735744</ref> It is sometimes restricted even further, to cover only those originating new financial products and strategies.<ref name=Dubil>Robert Dubil, ''Financial Engineering and Arbitrage in the Financial Markets'', Wiley (October 11, 2011) 978-0470746011</ref>

Despite its name, financial engineering does not belong to any of the [[Fields of engineering|fields]] in traditional professional engineering even though many financial engineers have studied engineering beforehand and many universities offering a postgraduate degree in this field require applicants to have a background in engineering as well.<ref>Entry requirements | Imperial College Business School. 2016.

[[Quantitative analyst]] ("Quant") is a broad term that covers any person who uses math for practical purposes, including financial engineers. Quant is often taken to mean "financial quant", in which case it is similar to financial engineer.<ref name="Haug">Espen Gaarder Haug, ''Derivatives Models on Models'', Wiley (July 24, 2007) 978-0470013229</ref> The difference is that it is possible to be a theoretical quant, or a quant in only one specialized niche in finance, while "financial engineer" usually implies a practitioner with broad expertise.<ref name="Lindsey">Richard R. Lindsey and Barry Schachter (editors), ''How I Became a Quant: Insights from 25 of Wall Street's Elite'', Wiley (August 3, 2009) 978-0470452578</ref>

"[[Rocket scientist]]" ([[aerospace engineer]]) is an older term, first coined in the development of rockets in WWII ([[Wernher von Braun]]), and later, the [[NASA]] space program; it was adapted by the first generation of financial quants who arrived on [[Wall Street]] in the late 1970s and early 1980s.<ref name="Derman">Emanuel Derman, ''My Life as a Quant: Reflections on Physics and Finance'', Wiley (September 16, 2004) 978-0471394204</ref> While basically synonymous with financial engineer, it implies adventurousness and fondness for [[disruptive innovation]].<ref name="Brown">Aaron Brown, ''Red-Blooded Risk: The Secret History of Wall Street'', Wiley (October 11, 2011) 978-1118043868</ref> Financial "rocket scientists" were usually trained in applied mathematics, [[statistics]] or finance and spent their entire careers in risk-taking.<ref name="Brown1">Aaron Brown, ''The Poker Face of Wall Street'', Wiley (March 31, 2006) 978-0470127315</ref> They were not hired for their mathematical talents, they either worked for themselves or applied mathematical techniques to traditional financial jobs.<ref name="Neftci" /><ref name="Brown" /> The later generation of financial engineers were more likely to have PhDs in mathematics, [[physics]], electrical and computer engineering, and often started their careers in academics or non-financial fields.<ref name="Stefanica">Dan Stefanica, ''A Primer for the Mathematics of Financial Engineering'', FE Press (April 4, 2008) 978-0979757600</ref><ref>Akansu, Ali N.; Kulkarni, Sanjeev R.; Malioutov, Dmitry M., Eds.

==Criticisms==
{{See also|Financial mathematics#Criticism|Financial economics#Challenges and criticism}}

One of the prominent critics of financial engineering is [[Nassim Taleb]], a professor of financial engineering at [[Polytechnic Institute of New York University]]<ref name=Taleb>Nassim Nicholas Taleb, ''The Black Swan: The Impact of the Highly Improbable'', Random House (April 17, 2007) 978-1400063512</ref> who argues that it replaces common sense and leads to disaster.  A series of economic collapses has led many governments to argue a return to "real" [[engineering]] from financial engineering.
A gentler criticism came from [[Emanuel Derman]]<ref name=Derman1>Emanuel Derman, ''Models.Behaving.Badly.: Why Confusing Illusion with Reality Can Lead to Disaster, on Wall Street and in Life'', Free Press (July 24, 2012) 978-1439164990</ref> who heads a financial engineering degree program at Columbia University. He blames over-reliance on models for financial problems; see [[Financial Modelers' Manifesto]].

Many other authors have identified specific problems in financial engineering that caused catastrophes:

Retrieved May 16, 2011</ref> posits that the "key assumptions" underpinning [[financial risk management]] are flawed.

The [[financial innovation]] often associated with financial engineers was mocked by former chairman of the Federal Reserve [[Paul Volcker]] in 2009 when he said it was a code word for risky securities, that brought no benefits to society. For most people, he said, the advent of the [[Automated teller machine|ATM]] was more crucial than any [[asset-backed security|asset-backed bond]].<ref>{{cite news |url=http://uk.reuters.com/article/usa-economy-volcker-idUKN2029103720090220 |title=Crisis may be worse than Depression, Volcker says |date=Feb 20, 2009 |publisher=Reuters |access-date=2013-09-05 |archive-url=https://web.archive.org/web/20130928083853/http://uk.reuters.com/article/2009/02/20/usa-economy-volcker-idUKN2029103720090220 |archive-date=2013-09-28 |url-status=dead }}</ref>

==Education==
{{Further |Outline of finance #Education|Quantitative analysis (finance) #Education}}
The first [[Master of Financial Engineering]] degree programs were set up in the early 1990s. 
The number and size of programs has grown rapidly, to the extent that some now use the term "financial engineer" to refer to a graduate in the field.<ref name="IAFE" /> 
The financial engineering program at [[Polytechnic Institute of New York University|New York University Polytechnic School of Engineering]] was the first curriculum to be certified by the [[International Association of Financial Engineers]].<ref>{{Cite web |url=http://www.poly.edu/academics/departments/finance |title={title} |access-date=2013-04-25 |archive-url=https://web.archive.org/web/20130410150319/http://www.poly.edu/academics/departments/finance |archive-date=2013-04-10 |url-status=live }}</ref><ref>{{cite web| url = http://archive.poly.edu/fe/people/faculty/adjunct/index.php| title = The Department of Finance and Risk Engineering| publisher = Polytechnic Institute of NYU| access-date = 2012-05-09| archive-url = https://web.archive.org/web/20140104064953/http://engineering.nyu.edu/academics/departments/finance?old=fe%2Fpeople%2Ffaculty%2Fadjunct%2Findex.php| archive-date = 2014-01-04| url-status = live}}</ref>
The number, and variation, of these programs has grown over the decades subsequent (see {{section link|Master of Quantitative_Finance#History}}); and lately includes undergraduate study, as well as [[Professional certification in financial services|designations]] such as the [[Certificate in Quantitative Finance]].
