Zcash extended the gains yesterday as renewed hopes for a US–Iran deal helped improve risk sentiment across crypto markets. Reports that Iran's security chief met with Supreme Leader Khamenei raised hopes of a potential agreement. However, a sustained recovery in ZEC will likely require more concrete progress, as setbacks or renewed tensions could quickly reverse recent gains.There might also be some pre-positioning ahead of the upcoming NU7 network upgrade, targeted for early November. The upgrade is expected to reduce block times from 75 seconds to 25 seconds and introduce changes to the network's fee mechanism, potentially improving transaction speed and long-term sustainability. Although, Zcash-specific catalysts can provide support for the cryptocurrency in the short-term, the macro fundamentals will still dictate the general trend.The focus today will also be on the FOMC decision, with the Fed widely expected to leave interest rates unchanged. With no new projections or dot plot expected, the attention will be on Fed Chair Warsh's comments and the statement's language. A hawkish surprise could strengthen growth concerns and weigh on ZEC amid general risk aversion. A neutral hold that avoids signalling imminent tightening, on the other hand, could support a relief rally in the cryptocurrency.
