If you have read the site’s Silk and Silver overview, you already know the shape of the expansion: a new trade system, roughly 900 duchy markets, playable Republics, and Merchants as the landless side of the commercial coin. This guide goes one level deeper, into the Merchant playstyle specifically. It is built from the two dev diaries that have focused on merchants, Dev Diary #3, Profit Above All: Merchants Vision, and the direct follow-up that iterated on it, and everything here is confirmed design rather than live content. Silk and Silver still has no release date, and it remains deep in development, so treat each detail below as the current confirmed picture rather than locked-in final mechanics.

One clarification so nothing gets tangled: this is not By God Alone. That expansion is the religion overhaul. Silk and Silver is the trade one, and everything in this guide belongs to the trade side of the Chapter V equation.

The confirmed Merchant systems

Merchants come with a bundle of named systems that the developers established in the first merchant diary and reference directly in the follow-up: Merchant Monopolies, Trade Expertise, Trade Contracts, Company Domicile, and the Merchant’s relationship to their Patron. Those are all confirmed real parts of the playstyle, and the honest state of the research is that beyond the names, no further mechanical detail has been shared publicly yet. A preview article can get a lot of words out of guessing what these systems do, and this one will not do that. What the developers have confirmed is written below, nothing more.

Trade routes, commission routes, and rival families

Merchants make their living on trade routes. Their own regular trade routes are profit-motivated, the merchant’s core business of moving goods between markets. Sitting alongside them are Commission Routes: offers that landed rulers regularly send to merchants in order to meet trade needs between markets. The merchant takes the job, and the ruler pays for it.

The rivalries are just as important as the routes. The follow-up dev diary dives specifically into the interplay between competing Merchant Families, confirming that rival merchant dynasties are a designed source of tension rather than background flavor. Two merchant houses serving the same cities are not simply coexisting, they are competing for the same contracts, the same routes, and the same favor. For the full mechanics of routes and their costs, the site’s Silk and Silver overview covers them in detail; this guide focuses on the systems the overview deliberately left shallow.

The Silk Road Participant Group

Merchants operating within the Silk Road region belong to a new Participant Group. The group grants bonuses to three things: the maximum Route Length a merchant can run, Route Capacity, and Expertise decay, which is how quickly a merchant’s trade expertise erodes over time. How large those bonuses are depends on the active Phase in the merchant’s geographical sub-region. No specific figures for these bonuses were given in the dev diary, and this guide will not invent any. The confirmed shape is that the Silk Road is not a flat bonus field: it is a set of sub-regions, each in its own phase that changes how much the group helps a merchant there.

There is an important ownership clarification here, because this is the detail most likely to confuse a player who does not own the other expansion. The Silk Road Participant Group works for anyone who owns Silk and Silver. It does not require the separate All Under Heaven DLC to function at all. What is gated behind owning both expansions is only the group’s interaction with the Dynastic Cycle mechanic, since Dynastic Cycle is a system that belongs to All Under Heaven, not to Silk and Silver. Own only Silk and Silver and the group works and its bonuses apply. Own both, and the Dynastic Cycle interaction comes into play on top of them.

Usury, loans, and the Creditor focus

Lending is where the merchant playstyle gets openly flavorful. A new Usury Doctrine has been added, which gives each faith its own distinct stance on lending money and profiting from it. Some faiths will treat moneylending as everyday commerce, and others as a sin, and the doctrine shapes how the realm around you reacts to the practice.

The crucial mechanical line is that any Merchant can Loan Gold, regardless of their doctrine. Doctrine changes the moral and social framing, not the availability. A merchant who wants to make lending their whole identity can take the Creditor focus, which turns moneylending from an occasional side activity into the character’s primary business.

When a merchant loans gold, the offer is not pocket change. It is a substantial sum scaled to the landed ruler’s income, because the whole point is leverage. In exchange for the gold, the merchant receives a Strong Hook over the ruler, and that relationship lasts for exactly as long as the debt remains outstanding. Picture the gameplay and the design intent is obvious: a merchant can put a kingdom into debt and hold a firm lever of influence over its throne until that debt is paid. Players coming from EU4 will recognize the strategic theme, and the site’s EU4 trade power, merchants, and steering guide covers the same commercial-leverage ideas in EU4’s own mechanics.

What to watch next

Two specific things are worth tracking in the next Silk and Silver dev diaries. First, how the Silk Road Participant Group’s Phases are determined: by geography, trade flows, era, or something else entirely. That single decision decides how central the region is to the merchant experience. Second, how the Usury Doctrine plays out across faiths with different stances, since a merchant operating in a realm whose faith condemns lending is a very different strategic animal from one working where lending is blessed.

The follow-up dev diary is clear that the developers are still iterating on all of this, so this guide, like the overview, is a living document that will be refreshed as new diaries publish. The shape already on the table is concrete enough to plan around, though. The Silk Road group decides how much geography matters, the Usury doctrine decides how much faith matters, and the Strong Hook decides how much debt matters. That is a merchant playstyle with real texture, and it will only get sharper as the developers finish iterating on it.
