In addition to the suddenly escalating global trade war, overnight traders had one more thing to worry about: another central bank unwinding its QE program. This happened shortly after midnight ET, when BOJ Governor Kuroda unexpectedly announced that the Bank of Japan will start thinking about how to exit its massive monetary stimulus program around the fiscal year starting in April 2019, and that there could be policy change before the 2% inflation target is achieved, marking the first time he’s provided any clear guidance on timing for normalizing policy.

“Right now, the members of the policy board and I think that prices will move to reach 2 percent in around fiscal 2019. So it’s logical that we would be thinking about and debating exit at that time too,” he said. “I’m not saying that the negative rate of 0.1 percent and the around 0 percent aim for 10-year bond yields will never change, but it is possible. We will be discussing that at each policy meeting.”

In immediate reaction, Japanese shares fell sharply, the Nikkei sliding as much as 2.9% as the Yen surged as much as 0.5%, with the USDJPY tumbling below 106, a 15 month low, while JGB yields jumped across the curve.

“Kuroda’s comments are important because he officially acknowledged a change in policy was likely before the end of fiscal year 2019,” said Rodrigo Catril, a currency strategist at National Australia Bank Ltd. in Sydney. “A move sub-105 yen over the coming days wouldn’t be surprising under the current risk off/trade war concern environment”

In testimony that lasted about three hours, Kuroda seemed to try mitigating the negative market impact by saying that this doesn’t affect his “overshooting commitment,” which pledges the BOJ to continue expanding the monetary base until inflation exceeds 2 percent in a stable manner.
