The Hungarian forint is facing renewed pressure as the market rally driven by Middle East peace hopes and falling oil prices has given way to caution.
Earlier in the week, the euro had dipped below 350 forints, supported by improving geopolitical sentiment and softer energy costs.
However, the trend reversed in the second half of the week as the Federal Reserve issued unexpectedly strict forward guidance, strengthening the US dollar and weighing on emerging market currencies.
Global investors are now turning their attention to critical US economic data, which is likely to dominate market sentiment in the coming sessions.
The shift in focus from geopolitical de-escalation to monetary policy divergence has eroded the forint's recent gains.
The currency had reached multi-year highs earlier in the period, but the stronger dollar has quickly unwound much of that progress.
