The Thai government, as any other government in the world, needs mre revenues in this time of crisis. More revenues to feed the US$ 41 stimulus package they just approved.

And one way to get more revenues is to raise the taxes on alcoholic beverages and this is exactly what they did 2 weeks ago.

For beer, excise tax went from baht 55 to baht 60 per litre, from baht 110 to baht 120 for white liquor, and from baht 280 to baht 300 for blended liquor.

So how much more are you going to pay?

Let's take the example of the beer. Beer is usually sold in 66 cl bottles in Thailand, so an increase of baht 5 per liter means you're going to pay baht 3.5 more per liter, right?  Wrong...

A bottle of Heineken in a supemarket was sold before the hike at baht 59. Today, it is baht 66, i.e. an increase of baht 7, double than the one coming from the rise in excise tax. Supermarket mathematics, I guess...

Not sure how much it increased in the pubs, they probably have different mathematical formulas also.

As for the stronger alcoholic beverages, I'm not sure how they calculated the new prices but considering they're far more expensive in the first place, the impact is little.

Here are today prices, picture taken in Carrefour Rama 4 in Bangkok, white alcohol (supposed to have increased by baht 10)

The price did not seem to have changed much but I'm not sure, I never buy any.
