5W E S T B A N C O R P O R AT I O N I N C . A N D S U B S I D I A R I E S bank today is deemed successful by the outcomes it achieves, but that’s only part of the story. True success is more than results—it’s about the journey: the vision, values, and leadership that shape the path toward those outcomes. It’s been said that the road to success is always under construction, and to be on that road requires constant decision-making to navigate detours created by outside influences, unknown variables, new competition, and most recently, governmental decisions. During March 2022, the Federal Reserve began rapidly raising interest rates to combat inflation. Over the course of the next year-and-a-half, the Fed implemented a series of aggressive increases raising the target range from 0.25% to an astonishing 5.25-5.50%. The result of this rapid acceleration in rates had a negative effect on the entire banking industry as increased borrowing costs created strains on liquidity, and thus an inverted yield curve. West Bank navigated this period and charted a course toward success on a journey that was unplanned but demanded decisive action. While many banks faced harsh outcomes, West Bank’s compass remained steady, pointing in the right direction. Consistent, sound decisions placed the Bank on solid ground and created a stronger foundation for the future. As West Bank continues its journey on the road back to great, it maps its course by weathering change, navigating detours, and charting a course forward toward long-term success. It continues its mission to build strong relationships, build strong communities, and build upon its strong reputation ensuring its clients and the communities it serves receive exceptional care and support. West Bank has been on this journey for 133 years—a journey that has shaped its very essence by taking the road to great one step at a time. Because West Bank has stayed the course, even when the road was challenging, it is emerging stronger than ever. A
