The current account budget deficit for 2008 is 3.4% and potentially lower. For 2009, it will be 2.9%. External debt is around 60% of GDP, which is very high, but should be manageable and will certainly be assisted by predicted GDP gains from 2010 onwards. The main concerns are high FX borrowing, which journalists exaggerate the importance of and low reserves, which could be a potential problem, if the ECB or IMF refuse to assist if they were ever required to do so. This is highly unlikely. Furthermore, local banks are in absolutely no trouble whatsoever and make record profits every year. Locals can afford the small FX mortgages they already have.
Aside from the externally-influenced currency issue, the Hungarian economy hasn't been more stable in recent history than it is at the moment. The 3% central bank interest rate increase should have an effect over the coming weeks. It is mainly a tool to prevent further speculation from outside interests. Nobody predicted an immediate response, although it has caused the HUF to increase from 282 HUF - 1 EUR this morning to 275.5 HUF at the moment. Of course, the HUF continues to be in a very vulnerable state.
Hungary is on a difficult journey and has very clear problems, which it is dealing with effectively, but there is no fundamental reason for the HUF to be so weak at the moment. It is a notorious country as it has had a very media-friendly economic shift/political scandal in 2006, which certain journalists still cling on to, as the facts of the situation are not as sensationalist as they would perhaps like them to be. I've read very little in the past few weeks about other much more vulnerable countries in the region such as Latvia, with much greater problems of 16% inflation and an out-of-control current budget deficit.
