yes, thank you. I am interested in the long-term consequences (10years+)

<p>The US Fed is increasing its interest rate targets. These rates will eventually affect most other interest rates in the US economy. In particular, interest rates on US government bonds will also increase, which should increase the US government debt servicing costs. Moreover, the government has over 10 trillion dollars in debt, so, the effect on its costs could even force it to increase tax rates. So, is the interest rate increase by the Fed eventually going to lead to an increase in federal tax rates? Thanks!</p>

It has been a bit since looking into it, but I think the fiscal theory of the price level argues that a government can cover such new debt issuance with seignorage (inflating the debt away) so that it is not necessary to raise taxes. I am leaving this as a comment and not an answer because I am not positive that this is entirely correct. Anyway - may be worth doing a bit of reading.

I think this is correct. Alas, inflating debt, means inflating the future debt service also...

The Fed may increase the rates. But will that make the government debt unsustainable?

  As projected revenue is growing slower than debt, ["Rising interest costs would force reductions in government programs"](https://en.wikipedia.org/wiki/National_debt_of_the_United_States#Risks_and_debates).

So, there could be either reductions, either change changes in tax laws.  
But the economic growth could also be stronger than projected.
