Asian stocks fell as investors were reluctant to add big positions ahead of key events looming in Europe and the U.S. The yen erased losses on a Bank of Japan report, while oil nudged higher.

The Japanese currency strengthened, weighing on the Topix index, on a report that the BOJ is re-calibrating its communications over how to handle a future exit from monetary stimulus. Oil recovered a small portion of the more than 5 percent plunge triggered by a report showing a rise in U.S. crude stockpiles. The MSCI Asia Pacific Index fell before the European Central Bank’s policy decision, the U.K. election and former FBI Director James Comey’s testimony. Hong Kong shares held gains as data showed an acceleration in Chinese exports.

A pivotal day for capital markets on Thursday comes as renowned bond investor Bill Gross said levels of risk in markets are at the highest since before the 2008 financial crisis. Equity investors have been prepared to place their faith in an expanding global recovery, while fixed-income money managers have dialed back inflation expectations in the U.S.
