Constancio, the outgoing vice president of the ECB is scheduled to speak. The politics of the replacement process is probably more interesting than any comments on policy – although how much Constancio echoes ECB President Draghi's dovishness may be interesting. Nowotny of the ECB is also speaking.
Harker of the Fed is speaking in Japan, and Bank of Japan Governor Kuroda is speaking in Zurich. The Fed's policy path is pretty clearly priced into markets, at least for this year, and the composition of the Fed is too uncertain in 2018 to allow one speech to influence longer-term expectations.
UK politics linger on, weakening sterling a little in Asia. There are reports of an internal challenge to the prime minister. The EU-UK UK-EU divorce proceedings are also generating contrasting signals (over jobs, and over the risks of a no-deal exit).
