The BOJ sets policy later in the session. The Nikkei newspaper reported, without citing sources, that policymakers will discuss tweaking the yield control policy to allow 10-year government bond yields above a 0.5% cap in some circumstances. The yield leapt to 0.505% in early trade.
The yen had earlier jumped about 0.5% on the report, gaining even as the dollar rose elsewhere after strong U.S. economic data and a toned down outlook from the European Central Bank. The yen was holding about 0.5% higher at 138.83 per dollar in early trade, helped by Tokyo consumer prices rising slightly more than expected and as the risk of a policy surprise spooked short sellers.
«I wouldn't be running short into the BOJ,» said Westpac strategist Imre Speizer. «I think the idea is even a tiny tweak is a big deal for the BOJ. We'll probably get a reaction either way.» MSCI's broadest index of Asia-Pacific shares outside Japan fell 0.4%.
Japan's Nikkei opened 1.4% lower though bank shares surged to an eight-year high on the prospect of rising interest income at lenders. «If the BOJ adjusts its yield curve control program, financial markets will likely take it as the start of a policy tightening cycle regardless of the BOJ's rationale,» said Commonwealth Bank of Australia strategist Kristina Clifton. «Under such scenario, we consider dollar/yen… can lose about two to four yen on the day.» A tweak would also cap what may prove a landmark week for central banks, with markets pricing a better-than-even chance that the Federal Reserve and ECB have made their final hikes of the cycle.
