Modeling the global economy in Victoria 3

How does the Victoria 3 market actually work?

The Victoria 3 market sits at the center of everything your nation does. Goods never move directly from producer to consumer; instead, every transaction flows through an abstracted market where buy and sell orders determine prices in real time. Each country operates within its own national market by default, with a Market Capital (typically the same state as the Government Capital) anchoring the whole system. Get the market right and your pops thrive, your buildings profit, and your nation grows. Get it wrong and shortages cascade through your entire industrial base.

What determines market prices?

Every good has a base price, which represents the equilibrium cost when buy orders equal sell orders exactly. From there, actual prices shift based on the ratio of buy to sell orders across the entire market. According to the Victoria 3 Wiki, prices can range from 25% to 175% of the base price, meaning they can drop as low as 75% below base or rise as high as 75% above it.

The formula the game uses is:

  • Price = Base Price × [1 + 0.75 × clamp((BUY − SELL) / min(BUY, SELL), ±1)]

To make that concrete: wood has a base price of 20. With 100 buy orders and 120 sell orders, the price works out to 17 (15% below base) because supply exceeds demand. That 15% discount is good for buyers but squeezes the margins of every lumber operation feeding that market.

One thing most players miss: the amounts bought and sold do not have to match. The game creates or destroys the difference in monetary value. When sell orders exceed buy orders, extra value enters the economy. When buy orders exceed sell orders, value is destroyed. This matters for understanding why oversupplied goods can actually be healthy for pop wealth even while they hurt producer profits.

How does market access affect your states?

Market access runs from 0% to 100% and represents how well a given state connects to your national market. The calculation starts simple: infrastructure divided by infrastructure usage. A state with 45 infrastructure but 90 usage sits at 50% market access at best.

Overseas states have an additional requirement. They need working Ports and Convoys through a shipping lane. Without enough convoys to support your supply network, overseas market access drops regardless of how much infrastructure you have built. Isolated states sit at 0% market access with no exceptions.

Low market access hurts in two directions simultaneously. First, it reduces how many of a state's buy and sell orders reach the national market. Second, it reduces the Market Access Price Impact (MAPI), which controls how much the local price in that state tracks the national market price versus a purely local price.

What is MAPI and why does it matter?

MAPI determines the blend between national market price and the state's own local supply-and-demand price. The formula is:

Local Price = MAPI × Market Price + (1 − MAPI) × State Price

With a base MAPI of 75%, a state producing iron but consuming none will see its local iron price pulled down toward the state price (low, because it is producing surplus iron) rather than tracking the national market. At 85% MAPI, the local price ends up at 35.5 when the national market price is 40 and the state price is 10, an 11% reduction from market price according to the Victoria 3 Wiki. That loss is real money leaving your iron mines.

Researching Stock Exchange and eventually Macroeconomics is one of the highest-value economic tech paths precisely because of this MAPI bonus. A well-connected, incorporated state under modern economic laws will have local prices that closely mirror national prices, keeping your producers competitive.

What happens during a shortage?

A shortage triggers when buy orders for a good exceed sell orders by at least double (a 2:1 ratio or worse). The shortage icon appears next to the affected good and the effects hit immediately and escalate fast.

According to the Victoria 3 Wiki, a shortage reduces the throughput of every building that uses the good as an input by −5% on activation, then increases by −1% per day up to a maximum of −75%. Recovery is slow: once the shortage resolves, the modifier only decreases by 1% per day back to zero.

The cascade problem is the real danger. A shortage of iron reduces throughput in steel mills. Lower steel throughput reduces steel supply. Lower steel supply can trigger a steel shortage. That steel shortage then hits every construction sector, tool manufacturer, and military production line that depends on it. The whole chain can unravel faster than you expect.

Fixes to prioritize:

  1. Build more production of the shorted good immediately.
  2. Import the good from another market via trade routes.
  3. Reduce consumption by switching production methods in buildings that use it as input.

How does trade between markets work?

Trade between separate national markets runs through the world market, which sits conceptually in the sea. To access it, your market area needs at least one Port, or a treaty with another country that includes Transit Rights while that country has a port-connected adjacent market area.

Trade is handled by Trade Centers, which can be built nationally or by private investors. Each Trade Center produces 10 trade capacity and consumes Merchant Marine as an input. The production methods on Trade Centers determine how many goods can be traded per unit of trade capacity, at the cost of more Merchant Marine consumption.

What is trade advantage and does it matter?

Trade advantage measures how dominant your country is in trading a specific good. At 100% trade advantage, you get a 25% better price on that good. The catch: trade advantage is zero-sum. Your gain is another country's loss. The world market price also has a monopoly bonus built in: if one market controls 100% of exports for a good, the world market price rises by 20%. Control 50% and the price is 10% higher.

Trade advantage components include:

  • Base: 100
  • +2 per percentage of global production within your market area
  • +0.5 per percentage of production controlled by a company with trade rights
  • +1 per percentage of prestige goods production (export advantage only)
  • +2 per percentage of trade going to a country in your treaty port

How do tariffs and trade laws interact?

Your Trade Policy law sets both the ceiling for tariffs and whether trade is possible at all. Tariff percentages apply to a good's base price, not its market price, which is an important distinction when goods are trading well above base.

Free Trade removes tariffs entirely but grants a flat +25% trade advantage, making your traders more competitive globally. Mercantilism gives you +25% trade advantage for exports but −25% for imports, pushing you toward an export-focused economy. Isolationism disables Trade Centers entirely, cutting you off from the world market (though you can still trade via Goods Transfer Articles in treaties).

Customs unions and power blocs

Customs unions merge multiple national markets under a single Market Capital owned by the market owner. They form in three ways according to the Victoria 3 Wiki:

  1. All subjects automatically join their overlord's market.
  2. Trade League power blocs are always customs unions, with the bloc leader as market owner.
  3. Other power blocs can become customs unions with the Market Unification III principle, again with the bloc leader as owner.

The Market Unification II and Internal Trade II power bloc principles each add a flat +20% tariff on all trade routes with non-bloc members, applying even to bloc members that have enacted Free Trade. This makes large, unified blocs economically self-reinforcing over time.

Members of a customs union share a single market, which means their goods all compete and balance within the same price system. A large, well-developed customs union can stabilize prices across all members, but it also means one member's shortage becomes everyone's problem.

Blockades, embargoes, and wartime trade disruption

War hits your economy through two direct mechanisms. Blockades let enemy fleets disrupt your shipping lanes and world market access. At 100% blockade strength, a blockaded sea node suffers:

  • −50% migration attraction
  • −75% shipping lane efficiency
  • −75% world market access
  • −75% throughput for Fishing Wharves and Ports

Capital ships carry roughly 10 times the blockade strength of equivalent light ships, so a single enemy capital ship squadron can lock down a port region fast. Use the Escort Convoys naval order to reduce the damage from enemy convoy raids.

Embargoes cost 100 Influence to impose and reduce trade advantage by 1% for both parties for each percentage of a bought good coming from the other market. War automatically triggers embargoes at no cost, and those drop when peace is signed. Members of a customs union or a power bloc with Market Unification I cannot embargo each other, though the automatic war embargo still applies.
