United Kingdom stocks and country-specific exchange traded fund investors may be too complacent about the impending volatility ahead as the country braces for its general elections.

The iShares MSCI United Kingdom ETF (NYSEArca: EWU) has dipped 0.1% year-to-date.

In the weeks ahead, BlackRock argues that investors could see greater volatility in the sterling currency and other U.K. assets on the prospects of an unstable minority government and a potential EU membership referendum after May 7, reports Aliya Ram for the Financial Times.

Others are also voicing concern over the possible political risk. For example, the Royal Bank of Scotland argued that “political risks look under-priced,” pointing out that markets can move swiftly, such as what occurred during last year’s Scottish independence referendum.

Last year, the sterling dipped to a 10-month low at the end of September after a poll suggested a Scottish independence was likely to pass. The British sterling has already been weakening against the U.S. dollar this year, with the CurrencyShares British Pound Sterling Trust (NYSEArca: FXB) has fallen 4.9% so far this year.

If the GBP continues to depreciate, ETF investors may find that currency hedged U.K. ETF options, like the Deutsche X-Trackers MSCI United Kingdom Hedged Equity ETF (NYSEArca: DBUK) and the WisdomTree United Kingdom Hedged Equity Fund (NasdaqGM: DXPS), could both outperform EWU. Year-to-date, DBUK is up 5.6% and DXPS is 5.0% higher.

Looking a the U.K.’s political landscape, observers believe that the Scottish National party could increase its representation in Westminster and tip the balance of power.
