USDHUF before 7.3% decline...

OANDA:USDHUF   U.S. Dollar / Hungarian Forint
I expect the exchange rate to decline in the medium term. The decline may last up to 260HUF against the US dollar . This is a drop of almost 7.3% from the current level. Why is it so big? I assume that the strengthening of the Hungarian forint and the weakening of the US dollar will be present at the same time, as a result of these two movements, a larger decline will be seen.
