美元/日元本周开局的平静不太可能持续，由于本周日本众议院选举结果难料，欧洲和美国的交易员将倾向于做空日元。事实上，此次选举可能会导致石破茂政府被削弱和不稳定，这也将成为日本央行推迟加息的又一个理由。

　　近期的盘中高点，如美元/日元升破150，都出现在亚洲交易时段之外。这表明外汇交易员偏向于看涨美元的策略，触发因素最初来自美国大选。现在，日本选举将进一步强化这种叙事。

　　虽然日元套利交易不太可能全面回归，但两次选举发出的信号，凸显出美联储降息慢于市场预期，而日本央行加息更慢的风险。美元/日元走高将是自然而然的结果。

　　如果美元本周获得上行动能，那么期权市场的上行通道比下行通道更清晰。此外，覆盖日本和美国选举的日元隐含波动率已回落至10%区域，这对美元多头构不成障碍。
