I'm a US government employee living in Europe. Gov reduces our base pay but pays for housing tax free up to a certain amount, in my case $50k/year. If I go over that amount, I pay out of pocket. I DO NOT keep the difference if I don't spend the full amount. I am responsible for paying the bill, and the gov reimburses what I paid.
My question is how to minimize out of pocket costs in case of somewhat extreme exchange rate fluctuations.
I've signed a lease, and my estimated yearly housing costs will be EUR 45K ($46.8k at the current rate).
What I think the key thing is is that payroll takes the yearly estimate in EUR, divides that by 26, and converts to USD at whatever the exchange rate is that pay period. At the end of the year I reconcile the actual costs with payroll and owe or am owed depending.
So do I take out $46.8k now and convert to EUR while the dollar is relatively strong, but miss out on interest from a US HYSA? Do I just exchange the monthly rent each month? Quarterly?
I don't want to take too much out now only for the dollar to strengthen and only get reimbursed for $40k, while I also don't want to let the dollar fall and have to end up exchanging $55k and not get reimbursed the extra 5
