Similarly, in 1907 Morgan again collaborated with Roosevelt to create a gentlemen`s agreement that would allow US Steel to acquire its greatest competitor, Tennessee Coal and Iron, in a tacit and unspoken rule that violated the Sherman Act. In 1890, the U.S. government imposed a ban on gentlemen`s agreements in trade and trade relations between nations. A gentlemen`s agreement is an informal agreement or transaction, often unwritten, which is supported only by the integrity of the other party to effectively comply with its terms. Such an agreement is generally informal, oral and not legally binding. In the worst case scenario, a gentlemen`s agreement can be entered into to practice anti-competitive practices such as pricing or trade quotas. Since a gentlemen`s agreement is tacit – which is not subject to the document as a binding legal treaty – it can be used to create and enforce illegal rules. A gentlemen`s agreement is easy to conclude and costs nothing. If you enter into an agreement that contains no significant value, a gentlemen`s agreement is preferable, as there is no reason to invest time and money in contract formation. Gentlemen`s agreements are often used in situations where it is considered shady or cowardly to hide behind contractual clauses.
Gentlemen`s agreements, because they are informal and often not written, do not have the same legal and regulatory protection as a formal treaty and are therefore more difficult to enforce. Gentlemen`s agreements have come to regulate international activities as the coordination of monetary or trade policies.  According to Edmund Osmasczyk in the United Nations Encyclopedia and International Agreements, it is also defined as “an international term for an oral and unwritten but fully valid agreement.”  This type of agreement may allow a nation to circumvent national legal requirements to enter into a formal contract or it may be useful for a government to want to enter into a secret agreement that does not engage the next government.  According to another author, all international agreements are gentlemen`s agreements because, just before the war, they are all unenforceable.  Osmaczyk noted that there was a difference between gentlemen`s open agreements and secret diplomatic agreements.  In the United States, in 1890, the prohibition of gentlemen`s agreements was introduced in interstate trade relations because the secrecy of these agreements was beyond anyone`s control.  A gentleman`s agreement, which is rather a point of honour and a label, is based on the indulgence of two or more parties for the performance of pronounced or tacit undertakings. Unlike a binding contract or a legal agreement, there is no legal remedy for violation of a gentlemen`s agreement.
For example, it is possible to conclude an oral gentlemen`s agreement on a loan. A regular loan agreement has provisions and legal consequences that determine what will happen if the loan is not repaid or compensated. Rather, a gentlemen`s agreement depends on the honour of the parties, which means that it is not a legally binding agreement.
