How to Increase Stability in HOI4

The most consistent way to increase Stability in HOI4 for any country is to do it through Decisions.

There are three ways you can increase Stability in HOI4 consistently as any country, without relying on the Focus Tree:

  • Improved Worker Conditions
  • Raid Political Parties
  • Increase Party Popularity

Improved Worker Conditions Decision

The best way to increase Base Stability in HOI4 is to use 100 Political Power to complete the Improved Worker Conditions decision.

For 180, you will gain 0.5% Stability every week, but your factory output will be lowered by 10%, and your consumer goods will increase by 5%.

Though this might sound bad for production, it is actually an incredible long-term investment in Stability.

The Stability you gain from this decision will remain with you for the whole game, while the debuffs will only last those 180 days.

Gaining 0.5% Stability every week for 180 days will result in a 12.5% increase in Base Stability.

This is a huge number, and you should use the decision as often as possible since it is worth the production debuffs and the 100 PP.

Use this decision the first chance you get, and then make sure you instantly use it when it pops back up.

Anti-Opposition Raids Decision

There are four parties in HOI4: Democrats, Fascists, Communists, and Non-Aligned. Depending on who you have as the ruling party of your country, you will have a decision to conduct Anti-Opposition Raids against the Democrats, Fascists, and Communists.

This decision will cost 50 PP, it will lower your Stability by 10%, but it will increase your Stability by 0.7% each week and lower the power of that party by 0.05 for 120 days.

Overall, if you take this decision, you will have an extra 1.9% Base Stability after those 120 days have passed.

However, this is just your Base Stability. Considering that you’ve weakened another political party in the country, you will also gain Stability since your ruling party is now more popular.

In general, though this decision can be a bit scary, it is extremely useful, and you should spam it as often as possible. The 1.9% Stability bonus might seem insignificant, but you can keep doing it for all of the radical parties.

If you are playing as a country with a Non-Aligned party in power, you can get around 6% Base Stability by raiding all three factions. The only problem is that you will also lose a lot of PP.

Promote Party

How popular your party is in the country is extremely important to Stability in HOI4. A huge problem that many players stumble into is that when they go to war, they gain a -20% Stability modifier.

It doesn’t matter if you’ve done all of the stuff from above since that changes the Base Stability.

Having 100% Base Stability will still result in 80% Stability if you go to war. However, your party’s popularity can combat the war modifier.

Ranging from 0 to 15%, you can gain a lot of Stability from your ruling party’s popularity. You get 15% Stability if your party has 100% popularity.

This is why raids are extremely important, as they will lower the popularity of opposing parties while increasing the ruling party’s popularity.

If you are playing as one of the major ideologies, you will also often have a Political Advisor that can increase the party’s popularity. Always get them, as they will indirectly increase Stability in HOI4.

There is a special advisor in HOI4 that will increase Stability by 15% and keep it that way throughout the whole game unless you fire them.

This Political Advisor is known as the Popular Figurehead and they are extremely overpowered.

Unfortunately, not all countries get the Popular Figurehead Political Advisor, making him a special bonus to some countries.

Since this isn’t a bonus all countries get, we decided they weren’t worth mentioning in the previous part.

However, it is good to know if your country has this advisor before choosing them, so here is a list of all the countries that have the Popular Figurehead Political Advisor in HOI4, or something similar, that will increase Stability:

  • Albania
  • Austria
  • Bhutan
  • Bolivia
  • Brazil
  • British Raj
  • Bulgaria (Women’s Rights Activist – +0.5% Weekly Base Stability)
  • Canada
  • China
